tuning problem sr20det with 520cc STI injector

[nickauger]

Hi! I'm from Quebec city, Canada so my english is not perfect. I have some problem to tune subaru injector (520cc yellow top, side feed), I have a power fc l-jetro and I try different lag time but my car never run good. I try .76ms, .72ms and 1.05ms. My air fuel is good with .076 ans .072 but my car run very bad when it was cold ... My air fuel drop at 17-18 when I try to start in first gear.

My setting is + 0.13 ms and 71% of correction 370cc/520

thanks for your help !

I'll be adding the same injectors soon also with a power FC. I'll try and search around for some info.

I just find that they are more like 500cc and this 7.66, 2.69, 1.37, 1.05, 0.75ms so 0.75ms at 14volt , 1.05 at 12v etc.

If you send me your map and paypal me 48 USD I will see if I can fix it.

should just be cold start adj and inj setting

include all your settings


either way look into your cold correction settings if the inj lag time .7 is working
