Stock ecu question (p13)

[Mishakol129]

P13 will work if you use obd1 H22 injectors and FPR to suit the ecu. Dont try running P13 with H23 injectors cause itll run lean

Yeah thanks for the heads up. Some dude I bought some H22 injectors from didn't come through and I never got the package, so I'm still in need of those.

BUT Ghost was saying something about how you could use your stock F22a/H23 injectors and just get a adj fpr and up the pressure so that the injectors spit out more fuel (more cc's). I'm wondering if this could actually work seeing that I already got a pressure gauge on my fuel rail. All I would need is a adjustable FPR and need to know what pressure to make them run at 345 cc (H22 stock injectors). Ghost, I need your ghostly guidance!! Ghostly and most perfect, for you are building a 2.4 liter ITB F22 motor, and know your shit.

To be completely honest with you! I would not suggest running an Adj. FPR and lower cc injectors with your current (planned) setup. You require a wideband O2 at the very least to do this properly.

Or you have to have access to a drag strip and be proficient at tuning fuel and ignition buy shooting a few 3rd gear WOT runs and reading spark plugs.

Best way for you to do this on the cheap, is to buy some OBD1 H22 injectors to go with your OBD1 P13.

^^What he said. Problem with adjustable FPR is you can get the idle and light load mixtures looking good but your WOT will be out. OR you can get your WOT mixtures tuned up but your idle and cruise might be out. Not really a viable solution for a street car.
