i just finished upgrading my friends fuel system with 850cc and 1600cc injectors with kg rails fpr and resistors. now i just need some info on setting them on the pfc so i can get the car to idle better. it idle rough and the wideband reads 10.5:1

ony info would be great just need to get it running a lil better so we can head to a dyno shop... thanks


this is a single turbo fd.

Hit up the PFC forum, 850 primaries has been covered ad infinitum. Also, if you don't have Chuck Westbrook's tuning notes, you need to get those as well.

you won't be able to adjust injector staging without a Datalogit.

 

i also think 1300cc is the max you can go on secondaries without a datalogit.

 

so i got som pim volts reading from some one on here with similar setup and now my car runs reall good.

but now my crank sensors dont read they stay stuck on 5 degrees and 10 degrees and sounds like car is misfiring my a/f idle was 11.1:1 now its at 13.8:1 and idles at 600rpms and sounds like its misfiring....
