Just a small point like ;)
When you advertise your chips it might be worth listing the mods they work with?
Just an idea? ;)
Good point - it's all on my web site so I wrongly assume people know. I'll edit the post above :)

are these chips on the same board as the stage 1 chips? if so would you sell the chips on their own?
Yes, they're on the same board. If you've got a stage 1 chip its really easy to upgrade to stage 2 or 3 - no soldering required and it takes about 10 mins :)

It does get a little confusing when comparing stage one to stage two and likewise with what mods you need for the chip hence why pointed it out.
I didnt realise your website listed the mods though..
:thumbs:
If only I had a FMIC and nismo 555 injectors.... :cry:
So how much is the upgrade for those of us with the stage 1 already?
If only I had a FMIC and nismo 555 injectors.... :cry:
I have :p , but my injectors are spraying fuel everywhere :cry: :censored: . As soon as that is sorted, Jez will be getting an order (sometime around Monday I hope :) )
Is that 289bhp@ wheels or fly?

Not sure yet - I'll put the prices up on my web site: www.h-dev.co.uk/site/prices.htm shortly :)

Its an estimated flywheel figure :)
Jez,
What's the lead-time like at the moment on these chips? For example, if I paid by paypal, how quickly could you get one to me?
I'm getting the injectors sorted out on Wednesday (thanks to the chairman whoring himself out :D ), and would like to get the chip shortly after that. The SAFC-II has already been set to drop by 33%, but obviously this is not ideal.
Thanks and well done for all the hard work sorting out us 14a chaps :thumbs:
I'm afraid they're selling very well - I'm having some more baords made up at the moment but they won't be ready for a couple of weeks.
I have lots of S14 boards, but run out of the S14a ones :rolleyes:
Is that the corrected figure mate?
A not insignificant ammount of tourque your making there, very nice :nod:
I have ..... run out of the S14a ones :rolleyes:
:cry:
How much of a problem do you think it will be to run with the SAFC-II marked down by 33% for a couple of weeks :confused:
Can you definitely put me down for one on the new batch, and I'll stick a cheque in the post, since there's no hurry ;)
I'm not 100% about the SAFC 33% thing - might be ok, although I've not mapped an SAFC with 555cc injectors so I can't be sure.
If you send me a cheque I'll send the chip as soon as they are ready :)
Hi Jez
I asked this before but didnt get an answer. Im interested in getting the stage 2 chip but looking at your graphs it shows the injector duty of the 555s at 80%. I thought (rightly or wrongly) from the calculations that 555s were good for nigh on 400bhp at 85% duty, whereas your graph shows 80% duty for under 300bhp. Surely with 5% duty cycle to play with, it wont get you another 100bhp. Im probably missing something but I'd rather get larger injectors than them running out of steam for what I want them for in the end as they arent cheap.
Thanks
Thats a very good question, and one I can't really answer. The 555s ar 85% should theoretically flow 377bhp, but with only 5% spare thats just not going to happen.
Either the injectors are flowing less than 550cc (although I don't think this is the case because the engine wouldn't run correctly as I've assumed a 370/555cc injector ratio, over standard) or the consult logging software isn't doing its sums correctly.
Either way, if the engine is running at the correct mixture I shouldn't worry too much about what consult reckons. I've never heard of an injector failing through an excessive duty cycle - probably because they would be at a high duty for such a short amount of time.
Jez, can i use other injectors or do they really have to be nismo's. as i can get some sard ones cheaper. or if i want optimumn power do i need the same ones that uv mapped with ?
I've not tried any other than Nismo 555s, so I can't say if other will work or not.
i tried to get my uk spec s14 1995 chipped and was told that it has to be uni chipped because it has a odd ecu will your chip be ok and will it use loads of fuel
I can chip your ECU.
What mods do you have? I'll be able to recommend which chip you should go for :)

Jez, I am interested in one of your Stage 2 chips for my S14a, and I would like to know a couple of things:
1. How soon can I get one?
2. Can I fit it myself, or do you need to fit it? (I live in Wokingham, but after I've fitted the injectors, it could get a bit complicated without a chip!)
3. How much will it cost me?
Thanks, Steve.
Hi Steve
1. I've got them in stock
2. If you're good at soldering you can fit the chip. See here for a guide: www.h-dev.co.uk/site/s14a-fitting.htm - it is a bit fiddly. I'm working on a dual map chip so you can easily switch from standard to stage 2 - this way I could fit the chip and then when you have the injectors fitted you could just switch over to the stage 2 map. This isn't finished yet though, should be ready next week sometime.
3. The stage 2 chip is £225, fitting is £25 if required.
Cheers :)
Jez
Iv been told that i should change my turbo for a pulsar gtir turbo! as i would get 1.2 bar to redline and more power/torque.
Wat r ur thoughts on this ?
Will ur stage 2 chip work ok with a gtir turbo ?

I think I can manage to fit it myself. Another question. Your guide says:
"Be sure to set the ignition timing so the engine does not detonate when on full load."
Can you recommend any guides on this or give any advice?
Thanks, Steve.

The GTiR turbo is an small upgrade, but probably not worth the hassle. The stage 2 chip should work fairly well with it though. I'd recommend sticking with the standard turbo on stage 2 and if you want more power go for a GT28RS and a stage 3 setup.

Theres a link in my sig which outlines detonation and adjusting the ignition timing :)
Let me know if you have any other questions.

Doh! Rightyo, I want a chip - do I just order it direct from your web-site?

No, just email me and we can sort out the details :)
Are you still willing to try with my blitz 550's?

Could do if you like - email me and we can sort something out.
I've just got back from a trip up to Anfield/Liverpool ( :cry: ) and back, via Rugby - a nice total of 460 miles and the chip has made such a difference to the car it's scary :nod:
1. Cruising at various speeds (obviously 70mph and below - I didn't cruise at 80 or 90mph, because that would have been illegal ;) ) for most of that journey has netted me 30mpg :eek: . I haven't had that economy since I put the air induction kit on 3 years ago!
2. In gear acceleration is fapping fantastic. The car picks up speed instantly from anything over 3000 revs in any gear.
Jez, may all S14a owners :notworthy to your godliness :D
Oh, and to put it another way, BUY THIS CHIP NOW
Cool :)
Glad you like it.
I like it, my wallet likes it, my car likes it, Shell garages hate it :D
289bhp dosnt seem like that much considering lots of people on here are getting 280bhp on stage 1 with a standard ECU!!!

Yeah - on the face of it it seems poor. However, the rollers I use are fairly pessimistic. For example, my car got 419bhp at the hubs at Thor, and on these rollers I got 409bhp at the fly. Many other people using these rollers get similar flywheel figures to Thors hub figures.
So, if I'd gone to Thor to get a figure the car would be around 290bhp at the hubs - which isn't bad at all :)
I'd agree with that Jez, seeing figures from both.
I'm considering the stage 2 too, mainly so I'm not stupidly pushing my injectors as I find it too slow to turn the boost down to about 12psi :ghey: to not push the injectors .... but thats just a AFM and turbo off Stage 3 :wack:
I might have to take my car to surrey RR then because I think the rollers i used were very very optimistic. They gave 343bhp@ fly and 286bhp@hubs, which at the time I thought :D but now i think these must be the most un-calibrated rollers in England :nod: Im only on stage 1 with a FMIC! I was peaking at 16psi but still........Im interested in one of these chips as i only need to buy the injectors. But id like to run my car before, to get a sensible figure! Then run it after fitting the chip to see just how much i have gained.
Jez im really interested in the stage 2 chip but the power ratings results are putting me off with all the free flow bits, 555 injectors, FMIC and the chip to producing 289bhp is really not what i was hopin for after spending so much money. What could be done apart rom the obvious to achieve the 325-350bhp mark with the this???? (Surely its pos with all the above mods)

I take it you didnt read this ;)

Bigger turbo will be essential to realistically (and 'reliably') get 320+ bhp IMHO. Jez's Stage 3 chip is nearly finished just for this setup (with uprated AFM)

As Andy said - read my earlier post :)
If you're after a real 350bhp you will need to upgrade the turbo and lower the compression ratio.
My stage 3 chip should be finished soon, which will produce around 320bhp at the fly / hubs (depending on which dyno you use) - you'll need the stage 2 setup plus a GT28RS turbo and a Z32 AFM.
Jez, could I run the stage 2 using a bren device to control the boost? I guess as long as it doesnt spike over 1.2bar it should be ok!
Yeah you can do, but you'll probably find that you'd struggle to get anything other than a 1.2 bar spike, tailing off a lot at high revs.
AFR on Stage 2 chips.
Hi Jez,
Been running 1.05 Bar on the stage 1 chip recently (used to be 0.9 apart from special occasions) and the EGT's have gone from 900max to 950max, so I'll have to turn the adj. actuator down for Castle Coombe :(
Question is, I was hoping to run 1.2Bar once the 555's arrive (should have left Oz today) and its a bit difficult to drop the boost up/down with just the actuator. Have you mapped it a lot richer to deal with the EGT issue on the stage 2 chip? Having recently checked my AFR on the same boost it is under 12 past 5000 revs anyway.
This is fine for the road but 40 min track sessions is another issue, would you advise saving for WI if I want to run over 1.0bar at trackdays or ... ????
Other thread (EGT's)
http://www.sxoc.com/vbb/showthread.php?t=149660
The stage 2 chip does run a bit richer, but the ignition is a little more retarded too.
My car (CA engine) runs up to around 950 deg C on trackdays with no probs - got to just over 1000deg C at TOTB on the top speed run :eek: The SR has sodium filled exhuast valves so it should be more resilient to higher EGTs.
I don't have any data on EGTs with my chips I'm afraid, other than what you have discovered.
At 0.9 bar
3rd gear to redline, then 4th to redline produces 900oC EGTs
trackdays ~925oC
At 1.05 bar
3rd gear to redline, then 4th to redline produces 950oC EGTs
trackday unknown, but I'm guessing 980, but may not actually want to find out :eek:
Remember my trackday car is also my daily drive .... I'll either have to go back to the bren device to adjust the boost, or save for WI. I suppose a 50:50 water/Methanol injection will also help AFR as MeOH is high octane fuel.
