IAT Fuel Trim Table


Recommended Posts

Morning Guys. Just working on fine tuning my car, spend a lot of time and money replacing the whole fuel rail, injectors, intake manifold, throttle body, fuel lines, plugs, coils, the whole thing. I want to make sure the IAT trim table is set correctly? Thanks in advance for the advise and explanation if it is wrong. 2002 Subaru WRX STI. rotate mount turbo conversion, front mount intercooler, cold air induction, 1000 cc injectors, TGV delete. If you need more info, let me know!

Is it using traditional fuel equation or modelled?  The answer to your question is really another question: Is the air/fuel ratio close to target over the range of normal operating conditions?
