You probably need to swap over the CAS wires on the ECU plug and move the fuel pump relay wire. The PFC has a different pin-out to the stock ECU in these areas. Car won't start unless they're put right.

I don't have the info to hand to tell you exactly which pins to change but you should find it if you do a search. Let me know if you get stuck.

sorry i haven't understand well...btw my car is a s14a,so do you think i have only to swap some wire?thanks!

[Roo]

Yes, that's right. You need to swap 4 wires for the CAS (crank angle sensor) and move one wire which goes to the fuel pump relay. I had to do this on my car which is also an S14a. The details of the wires to change can be found if you search on here - I know I posted them to someone else on here a little while ago and think I have also seen them in other threads.

thanks!some hint for keyword to search?

Fuel pump relay:

Move the wire from 106 (standard ECU) to 104 (PowerFC)

Camshaft Position Sensor:

Swap the following wires around

22 -> 31
30 -> 40
31 -> 22
40 -> 30

last thing,for not have mistake when i do everything.....i found thi ecm able on s14 manual,buit the s14a is different,but i need only number position isn't it?or i have to find proper a s14a table?thanks!

[cervus]

[Actual_Ben_Taylor]

Check the 'Useful Threads' sticky at the top of this section (or use the search )

[water-ninja]

here is what i found this was for my s14a

[cervus]

thanks to you too,ninja!i download the s14a manual and do the swap,now everything work well!


now other question,is there a way to rich all the map?because when turbo start to load i have some knock and i think it's lean....thanks a lo!

[luca_200sx]

no manuel you have to change point by point

[Actual_Ben_Taylor]

The map is very rich anyway, try taking some timing out instead

[cervus]

ok,today i try to take away 1 degree of tuiming,now is at standard 15°

[Actual_Ben_Taylor]

Don't adjust the Camshaft Position Sensor, change the timing with the commander.

Use the 'test mode' on the commander its under Settings - Ign/Inj. Keep reducing the timing by a degree at a time untill the knock goes away. Then you'll know how much timing you need to take out of the map.

Use the Map Tracer (Monitor - Map Tracer) to see where in the map knock is occuring and reduce the timing accordingly.


On a side note, if you don't know what you're doing with the commander then don't mess with it. Just turn the boost down and take it somewhere that can set it up for you.

[cervus]

i'll try with the commander like you say ben,but i don't know what to do and i prefer don't touch the map,i'm only searching a configuration that work well for a few time because before set it up i have other mods to do and don't want to set it up 2 times.....today i try,if it won't work well i reduce some timing on the cas for the moment....thanks ben

[luca_200sx]

manuel search the fc commander manual on the web!
you can find the fd3s one

hi, is there any difference between the s14 and the s14a on the ecu wiring? have a japaneese ecu from force from a s14 and want to mount on an s14 but the connection doesent seem to be the same. thanks.
