Power fc trouble shooting

[RB20LagWagon]

Hey guys i just got a power fc for my rb20 which is r32 spec but in a r31.

I plugged it in etc

Have power to the ecu when i turn key it primes (for shorter then old ecu) and it will crank but it wont turn over. The tune in the ecu is for a similar spec car but is tuned for 550 injectors not the standard ones that i have. i dont want to drive the car or anything i just want it to turn over and see how it works.

Any ideas, i dont really want to reset the tune because its probably useful.

Cheers

Sean

The injector pulse timing for the 550cc injectors will be completely different to the standard injectors which is probably the start of your problems.

Are you sure you've got the right pfc....I understood they didnt make it for the 20DET

Just go to the setting menu, then injector and change the the Injector Data from 100% to (old injectors cc/min)/(new injectors cc/min)*100. This will get you in the "ballpark" of where you want to be.

You can also go into the Ign/Inj menu and screw around with the Ing settings till you find a setting that runs nicely (keeping an eye on AF of course) and you should be fine. Then once you work that out, apply the fudge factor that worked well to the Injector Data and Bob's your father's brother...

Ok thanks guys for the info so far i will give it a burl. AP engineering do a special pfc specially for rb20

Just out if curiosity what are your current settings for the Injector Data?

[RB20LagWagon]

For five fifty injectors they are at 68% and .30 ms i think the 6th injector is 68.5%

I still cant get it turning over tried everything that has been said, i spose its off to hyperdrive
