I have a safc 2 hooked up to my car right now they guy I bought it from installed it. I'm going to get dsmlink in the near future but for now I have the safc /ubbthreads/images/graemlins/frown.gif my problem is when I have it set to the correct starting point which I figured was 0%I have a 2g maf and 550 injectors. Everything else is pretty stock. My afr gauge doesnt show anything at idle meaning its way to lean where the gauge doesnt even go that high. I richen it up on the safc to where its around 14.7 on the afr and its around 19+ on the safc I can drive it for about a day and it dies and won't start up until I go alot lower on the tune. Has anyone else had this problem and if so is there anyway you were able to fix it. If there is a similar post please direct me there. Thanks

I've had bad WB and O2 sensors do this. What are you using to measure the fuel and what are you logging with?

I have a aem wb i had it in my lancer and it seemed to work fine. It also dies a lot if I just let it idle with no throtle but after it warms up for about ten minutes its ok. Think it might be related?
