View Full Version : *** S14a stage 1 chips now available ***
As the title says, S14a stage 1 chip are now ready for sale.
Please see my web site for details: www.h-dev.co.uk :)
Think you should have @wheels BIGGER, or more easily spotted.
If your going to be using my graph I'll take it to work next week and scan it instead of taking a Digi-Cam picture of it.

Good point.
I meant to ask you if it was OK to use your graph - sorry :smash: hope its OK :) Got carried away with me pictures :wack:
Whooooo! :D After xmas tho :cry:
No probs Jez, of course you can use my graph, but I'll get you one that looks better.
Congrats :notworthy: and thanks, pity the mid-range pickup improvements cant be shown ... unless we can get some 45-100mph times sorted. This is the big winner with the chip.
Cool - cheers - a proper graph would be superb.
I'm going to do a "testimonials" section for all the chips, but the fecking search is broken. The S14a ones wouldn't be so bad as its all recent but the others are lost in the SXOC database...

Jez, the site looks :thumbs:
Am really looking forwards to being able to write a testimonial! Like I have said before, what I am after is a det proof system, but sounds as tho the remap is going to be much more than 'just' that.
Cheers

right so the first set of results were with std wmic.. and you say theres a 18bhp increase with the chip.. but the car isnt 200bhp at the wheels thought is it?
thought those std stats were from the fly? or am i again wrong? (more than likley)
also whats the tunability with the chip in place?
i mean i see you just added a fmic on there and the chip worked very well with it, does it work if your to add other stuff as well of does it upset the mapping
i guess it should be ok as on the std ecu we all mod our cars and they work fine, the chip will just impove the settings to what we have to make it all run as safely as the std ecu with no mods.
also prices?
it says in the price list, £175
how hard is it to fit the chips?
jez
have you or can you adjust the vvt settings with the chip so that it doesnt rattle like bitch on start up. I thought i had seen on another thread that this could be done.
cheers

Hi Jez :wave:
Would it be worth me waiting for the Stage 2 chip ?
I will have the folowing on the car
Standard turbo
Front mount
15psi Boost (AVCR)
Walbro fuel pump
Blitz BOV
Blitz NUR-Spec R exhaust
Blitz Sonic Power Induction Kit
Decat pipe
Front pipe
IK24 Plugs
Nick
OK
The 1st graph on my web site is from what consider to be a fairly conservative set of rollers. They measure 217bhp at the wheels - std car is 200bhp at the flywheel.
The second graph is from a car with the stage 1 chip, but with a little more boost (1.1bar) and an FMIC.
Theres a fitting guide on my web site: www.h-dev.co.uk/site/s14a-fitting.htm - fitting can be tricky, although any experienced tv/audio repair shop could fit it no probs. If you have any doubt about fitting the chip, I can do it: pop round or send your ECU to me, guaranteed next day delivery.
The vvt rattle at start up is not something my chips will fix.
Vidal Babboon :wack: : the stage 1 chip will suit your car very well. If you want to increase the boost pressure above 1 - 1.1 bar and fit 550cc injectors the stage 2 will be good, when it's available :)
Upgrades from the stage 1 chip to stage 2 and 3 will be available in the near future. The expensive bit is the daughter baord, so upgrades won't be too expensive.
Nice one, Jez :thumbs:
I know it's been a long hard slog to get to this stage :) Will await future developments with interest :) :thumbs:

Cheers :)
Its been very tricky, but got there in the end. And from what people say, it's been worth it :)
whats the max boost you can run on the stage 1 chip, you mention 1.1 bar for the second dyno graph
in the how to part you say at the end you need to adjust the ignition timing. How do you do it ? or would i have to go to a garage to get it done?
You can run around 1 bar with a WMIC and about 1.1bar with an FMIC. Obviously this will depending on your car and the components you've chosen. I've tested on a few cars now and these are fairly conservative settings so should be fine on most cars.
To adjust the ignition timing you need a timing gun (you can pick them up at halfords for about £30) and then adjust the cam angle sensor to get the idle ignition to 15 deg BTDC. Most garages can do it or I can do it. If you look at page EC5 in the S14 service manual (http://bagpuss.swan.ac.uk/horsham-developments/manuals) (not the S14a supplement) shows the position of the "Camshaft position sensor" and the timing adjustment is described on page EC33/34. 15 deg is the recommended setting anyway, so in most cases it shouldn't need adjusting much.
ok thanks i'll be after one very soon :D
I assume you can fit theseplus, set up an avcr and fit my injectors?
I don't live too far from you and assume a stage 2 is what I would be after with the following mods:
Full zorst
Fuel Pump
Induction
Tubular manifold
Colder Plugs
FMIC
550 Injectors
z32 AFM
AVCR
The stage 2 chip will be for a car with 550s and the standard turbo
The stage 3 will be for a car with 550s, Z32 AFM and a bigger turbo.
I hope to get the stage 2 chip done early next year, and the stage 3 shortly after :)
I've just written a quick guide on how to adjust the ignition timing - its on my web site in the links section. :)
Stage 2 it is then, unless I have my new tubby by release date :)
I assume you will be happy to take my cash to help with fitting other bits to do it all in one go? :nod:
Hoo-ahhh :whip:
Well I deffo want one and will have the cash, so if you can put me on a pre-order list or sommat and let me know when you are ready :thumbs:
Does the chip remove fuel cut?
If a standard car was to be modified to run this chip, what equipment is optimum for it?
If a standard car was to be modified to run this chip, what equipment is optimum for it?
The stage 1 chip is designed to optimise the fuelling and ignition for an S14 with the following modifications:
Free flow air filter
Free flow exhaust
Uprated fuel pump
15psi boost pressure
Translates to full de-catted turbo-back exhaust.
K&N Panel and airbox mod OR Induction kit
Walbro fuel pump
Boost controller.
Thanks, I did see that but wasn't sure if the chip was done with specific makes in mind or not. :)
Cheers SM :)
taser, SM is right. The chip is optimised for the mods he mentions. There's more info on my web site.
Lennie, yes the chip removes the fuel cut.
Does the chip correct the fuelling for atmospheric dump valves? ie.stop the popping? Or is there still a few explosions?
Atoms dump valves will still mess up the fuelling on gear changes and if/when they leak. Can't do much about it I'm afraid :(
theres nothing wrong with that :)

can i still fit the chip without turning the boost up?
Nice work Jez :)
Will the car pass an MOT with the main cat re-fitted with one of your chips?
nice work jez :thumbs:
Will be looking at getting one after xmas :nod:
Cant wait :D
can i still fit the chip without turning the boost up?
Yes, but you won't see a massive gain.
Will the car pass an MOT with the main cat re-fitted with one of your chips?
If it passed before the chip, it will pass with the chip.
Will be looking at getting one after xmas
Cool :)
I'll be getting one in January too. Is it a case of putting one in a box and posting it down?
Yup - the stage 1 chips are in stock :)
do you need to know the number on the ecu?
yes, it'll be something like 23710 xxFxx :)
yes, it'll be something like 23710 xxFxx :)
i'll go look now, has the money cleared yet?
23710 82F04
Hi mate
Thats cool - the money cleared today. I'll get the chip in the post asap :)
Thanks for the order
Cheers

on your site it says that the stage one chip and a FMIC it produced 280bhp i am assuming that this is with out the stage 1 mods such as exhaust or is it with the stage one mods?
i have all stg 1 mods plus a FMIC and run 13psi, from searching the broad this is pretty much maxing the injecters. is the chip going to work well with this set up or should i get bigger injecters and wait for the stg2?
also woll your chip fit my ecu 23710 74F05?
The stage 1 chip is for a car with the usual stage 1 mods: exhaust, filter, fuel pump and 1 bar of boost. It will also work well on a car with an FMIC up to 1.1bar and the fuelling will be fine.
It'd suit your car quite well, and I can chip the 74F05 ECU. :)
it arrived today :D i'll be fitting it as soon as i get my soldering iron back of a work mate.
should the timing be set to 14 or 15?
It was mapped at 15, but 14 will be safer. All depends on your particular engine. Just be sure its not detting (which it shouldn't assuming you follow the guide lines :) )

Sounds to me like I might have to pay you a visit in the new year mate :)
There is no way in hell im going to do it DIY style lol
Will give Phill a day out at the same time lol
Cool - just let me know when you wanna pop over :)

may come too, turns out there is still the S14 chip in mine so i'll have one of them :)
I've just written a quick guide on how to adjust the ignition timing - its on my web site in the links section. :)
I guess we can use the DIY consult to monitor the ignition time at idle (instead of the ignition gun), and adjust it with the CAS like you explain in your WEB. Right?

No - fraid not. The ECU will only tell you what it thinks the ignition timing should be - not what it actually is. You have to set the ignition timing to 14-15deg BTDC with a gun while the engine is at idle and warmed up.
Found this out after fitting the chips at the weekend :rolleyes:
First impressions of the the chips are great, although I am only running at 13.5psi with a uprated wing mount and the timing set just under 15BTDC.
The car feels a lot more alive on and off boost.
Hopefully this week I will be fitting a blitz FMIC and turning the boost up to just over 1 bar :nod:
I fitted a knocklink before I installed the chip, and there is no change in that :) , also tried the copper pipe method :wack:
Very pleased with the chips though :D :D nice work Jez :thumbs:
excellent - glad you like the chip :)
How was the fitting? Obviously you got it all in OK. It'd be good to compare the knocklink and copper pipe method - unfortunatly I don't have a knock link...
When you fit the FMIC and up the boost, remember to check for det again - it should be OK up to about 1-1.1 bar peak boost
Yeah fitting was good the board fitted like a treat :thumbs: , but the soldering may be a bit tricky for someone without soldering experience, as the pads are quite small and could be easily be fecked up :smash:
I did think about using some type of connector so I could remove it for any reason, don’t think the pads are going to like being reheated to many times.
The knocklink has five leds, green, green, amber, amber, red. The second green came up before and after the chip, at around 6500.
The first amber started to flash at 7000 but that was really ragging it (well teaching a Alfa GTV to back off :D ).
Cool :D
If you find any connectors that you think will work, please let me know. The ribbon cable is impossible to find too - its a weird pitch (1.78mm / 0.07") - if you find that anywhere I'd be very grateful :)
I fitted a knocklink before I installed the chip, and there is no change in that :) , also tried the copper pipe method :wack:
Hello, where did you get that knock gauge? Is it accurate? Easy to fit and set? Price? :wack:
Thx!
Yeah I bought it from a mate, who has only had it on his scooby for a few months because he had the ecu tek3'd. But now he is selling up :)
He got it from http://www.brdevelopments.com/link.html think there about £130 but I did not pay that ;)
As for accuracy, I know the scooby boys use them alot :nod:, and its just 0V & 12V then two cables to the sensor. Which I mounted near the cam angle sensor on the side, covered in plenty of tin foil because it was a bit near the manifold. But thats the best place I could find.

i assume that these chips are removable/reversable?
quite interested in one.
will give you ECU details then place order

You can remove them, yes.
Email me if you'd like to place an order :)
finally got round to fitting mine today.
feels like its made a hell of a difference. Its the first time i've spun the wheels in 2nd just by accelerating i know its a bit cold out there but then realised the boost controller was still turned off so was only 7.5 psi of boost.
would disconnecting the ecu for a time reset something? just feels so much faster now, and you said there wouldnt be much gain at low boost?
it seems to fly now though :D :thumbs:
Excellent - It should feel better :)
It'll go even quicker if you get the boost up around the recommended level :D
i have low boost set to 10.5psi and high at 13.5 psi it feels quick :D
i'm not sure what det sounds like but i get a weird rattle type noise at around 3k but no where else in the rev range
Hmmm.... rattles are bad.
Does it only do it with the boost turned up? What is your ignition timing set to?
no it was doing it with the boost controller turned off so about 7.5 psi i'll check the timing tomorrow gotta find the timing light its somewhere in the garage
yeah check it out - it'd have to be very advanced for the noise to be det at 7.5psi...
No - fraid not. The ECU will only tell you what it thinks the ignition timing should be - not what it actually is. You have to set the ignition timing to 14-15deg BTDC with a gun while the engine is at idle and warmed up.
:confused: Really? then the ECU invent or calculate Ign.T? :confused:
Well, not really a thread to develop this, but just to clarify. I'm confused because when I take Ign.T. front consult running the car, the car feel exactly like the Ign.T was, changing quickly his behavior according to it.
So, do you mean that if I change the CAS to change Ign.T front 15 to 14, the consult will keep showing 15? why?
Thanks.
So, do you mean that if I change the CAS to change Ign.T front 15 to 14, the consult will keep showing 15? why?
Yup - this is because at idle the ECU expects the ign timing to be at 15 deg BTDC. If its at 14 deg at idle then all the figures that the ECU reports will actually be 1 degree less.
Hi Jez, Does the chip run with this ECU : 23710-69F01 ? Thx.
Does the chip run with this ECU : 23710-69F01
I'm not sure. The ECUs in the UK are 82Fxx or 74Fxx - never used a 69F01 before. You may not want to do this, but if you send me your ECU I can fit a stage 1 chip to it no probs.
HI JEZ,how much do you charge to fit these and check the timing?
Also how many can you do in a day as myself and mart gti6 are interested,may convoy up with baboon aswell?
thanks. paul :thumbs:
It takes about 1/2-3/4 of an hour to fit the chip and check the timing. Fitting and timing check costs £25.
If all 3 of you want to come over, let me know - we will be able to sort something out :)
Thanks jez,have pm'd mart and baboon.will sort out something in new year :thumbs:
HAVE A HAPPY NEW YEAR
PAUL.
Will I still be able to get one of your chips if I've got 22's not 24's?
I'm assuming the answer is yes, though I might be advised to stick to a slightly lower amount of boost than 15psi?
The car doesn't often get really hot, and doesn't get any trackday use. However I do go drifting every month or two, and the car gets a right hammering then :)
Cheers
So long as it doesn't det it'll be fine :)
Guess I'll need to make a det detector then :) Cheers

Yay! :)
Just got back from Ali G's home-land, Berkshire, but luckily Jez was there aswell.
45 mins after rolling up, and £200 later, a shiny new ECU chip and a newly timed engine left Jez's house, and First impressions are good :)
I had a bit of fun on the first r/bout (forgot TC was off... :rolleyes: ....afew fishtails later.... :thumbs: )...But after that, all good. Car feels alot more alive off boost, and 2nd gear now really feels potent ATM.... (could be just the cold weather though..... :D )
Ive yet to see the reality of a promised 0.5mpg gain though...... :whip: ...reports on that later.
Anyway, thanks again Jez....
Andrew
i'll drive east along m4 when the weather's warmer and you can fit one for me :)
Cool - just let me know when you're ready :)
Hi jez :wave:
took my car out for the first proper spin since having the chip fitted and it is a lot quicker :thumbs: had'nt noticed so much on journey home as it was almost door to door motorway,but boy coming off roundabouts etc it is awesome :Plug: i am :D :D :D :thumbs:
Cool - glad you like it :)
Bah.... i really want one of these for my S14, but i simply cannot afford one for a couple of months.
Will this chip completly eliminate pops and bangs? I know its a good thing to reduce them, but i do like the visceral (sp?) thrill they provide :)

I don't think it'll have much effect on the amount of pops and bangs - have to ask some of the people who are using the chip to get their opinion :)

Really? I always put it down to overfuelling at low revs which i assumed would not be the case post chip :confused:
Still, if this is the case then i am all the more eager :nod: :thumbs:
Thanks for your quick reply (again) :)
Still get as many pops as I used to.
Occasionally get a few on overrun/lifting off, but most come from blipping throttle on down changes....

Top news, i have no excuse not to get one as soon as funds allow :nod:
Thanks for confirming that J.. :thumbs:
I haven't noticed as many pops,engine has to be really hot.there again i'm still only hitting 13psi :thumbs:

No differance for me, but the LPG pops and bangs immensly :wack:
I would have thought low down pops and bangs would be BOV related, as are flames on lift-off.

Just thought i'd let you guys know, that after having the chip for around 1 month now, I'm happy with it still :)
Still finding the extra power useful, and the best bit, the fuel economys got better :)
I used to get about 220 from a full tank, its now closer to 255 :)
Saving me £5 a week, the chip will have paid for itself by summer!
Not too sure if this is due to the Timing, or the chip, but ether way, its all good...cheers
GET ONE! :nod:

hi jez what chip would you recomend with my spec i guess the next step for me would be injectors and a turbo but i would still run around 1.1 bar boost. would the stage one chip be ok i have a safc2 so could this be adjusted to compensate if i were to get bigger injectors and does your chip rase the rev limit? :thumbs:

The stage1 chip would suit your car well as it is at the moment at 1 bar boost. In the future if you decide to go for bigger injectors you could upgrade to the stage 2, which is for Nismo 550cc injectors and 1.2bar boost. Then if you go for a bigger turbo you could go for the stage 3 which will be mapped for 550cc injectors, Z32 AFM and GT28RS turbo.
Along the way you could fine tune the setup with your SAFC.
The rev limit is at the standard 7000rpm on all my chips. Power usually drops off before 7krpm anyway, so there is little point in raising it.
At the moment the stage 2 and 3 chips are in development, but should be ready soon.
Hope that helps :)

No probs :)
There will be an upgrade price list out soon - If you wanted to go from stage 1 to stage 2 you won't need to completely replace a stage 1 chip with a stage 2. You just need to swap a couple of socketed chips - 10 min job :)

Would the 14a chip benefit a car with Apexi Safc fitted?
Cheers :thumbs:
James
Maybe - the SAFC can alter the fuelling but a by product of that is that the ignition timing gets altered too - sometimes for the better but sometime for the worse.
quick question would you travel to do 4 or more of them? :)

Yeah, could do - I'd need somewhere to fit them though: somewhere dry, mains power and a table.

About the timming gun, shall we look for any feature / recommendation, or just buy the cheapest one front Ebay?
Thanks!
Cheap is fine, all you need is one that flashes when the no.1 plug sparks :)

that's interesting. i was thinking of fitting one of these fuel ecomomy chips.
any ideas what a mature sxoc'er who usually gets 330 to a tank would see with a stage 1 chip jez? particulalry at the 70mph light throttle cruise mode:nod:
I've never done any proper tests, but most people see an increase in fuel economy :)
heads over to s14 tech to create a poll......:D
