Got a minor problem with the 1ggte which is now running a stock ecu, timming is right but it has just decided that it wants to lean out the fuel mixtures and i have nfi why it is doing it, has any1 else had the same isssue and if you did how did you fix it?
Cheers Adam

First thing I'd look for is air leaks, specifically between the AFM and turbos.

Tis all sealed fairly tight, one line that goes to the stepper motor and one to the crankcase venting the rest is just a metal pipe.

Adam, check your fuel pump delivery pressure. If you dont have access to a guage, a quick test,is to clamp off your fuel return line, and check AFR.

I tried making it richer doesnt work, though i did change afms and it did run better but i wasnt allowed to asjust the afm so chances are the spring on mine might be fuggered but it did make a differecne to it when adjustmted though. What does AFR mean?
