One will plug straight in, the other won't... Simple as that.

And as Apexi never made an S14a d-jetro you have to buy the S15 one if you want it to plug straight in.

I have a SR swapped S13 which runs an Apexi PFC. The device is not tuned yet and the car is running a base map.
What kind of map is it?
Can I do a weekend of drifting without changing the map...?

Not really, base map is okay to get you to the tuners imo. Doing a whole day if drifting is a bad idea.

Don't do it

map is no good for hard driving and definitely no good for drifting.

hi, i got a problem, i have a s13 (200sx-eu version) with a s14a sr20det engine
i have installed my apexi but it doesnt work

so i have do following pins:

Fuel Pump Relay:
106 no pin
104 no pin

i dont find the pin for my fuel pump relay

i try 18 (like s14 pin) but i dont work

so i dont know where is my fuel pump? but my engine my car is running before and is running with the original ecu

Camshaft Position Sensor:
22 -> 31 i do it
30 -> 40 i do it
31 -> 22 i do it
40 was no pin so 30 is free (no pin now)

thanks for your help

It's far easier to swap the signal wires at the cas unit.

**reshizzo** · 15-06-2012, 17:46

???

**VIDAL BABBOON** · 15-06-2012, 18:13

What ECU did you have before installing the Power FC ECU ?

Was it a UK spec S14-A ECU ?

Only reason i ask is the S14 ECU does not have a pin 40

Also the S14 ECU does not need any wiring swapping to work on the PFC.

**reshizzo** · 15-06-2012, 18:50

yes its a s14a uk ecu!

yes but the s14 has the fuel pump on 18 or? but i take the 18 to 104 and it doesnt work same
and when i fit the genuine ecu than he run without the pin 18 so i think thats not the fuel pump

i was told its a s14a .. and i know its a s14a .. but the wiring harness its a horror

**Actual_Ben_Taylor** · 18-06-2012, 13:58

What's the part number on the Nissan ECU?

What's the part number on the PowerFC?

**reshizzo** · 21-06-2012, 07:28

sr20det ecu part number:
23710 74F00
A18-CO3 G72 4414

apexi pfc ecu part number:
PFC SR201 9902- 0006

is that ok?

**reshizzo** · 21-06-2012, 07:52

its a s14 ecu

**reshizzo** · 21-06-2012, 12:14

and i think my apexi pfc its for an s14a engine

**VIDAL BABBOON** · 21-06-2012, 22:00

If you have an S14 ECU originally and the PFC plugs directly into the loom then you dont need to swap any wiring

As i posted earlier S14 ECU does not have a pin 40, so it does sound like you have an S14 loom and ECU.

If this is the case then you do not need to swap any wiring around on the loom and it's a direct plug and play.

ALSO an S14-A PFC will not fit the S14 Loom
