I had to guess as to what wideband is installed in the car, I used the innovate wb, if that is not the WB you have in the car it wont take long to redo the fuel table.

Can you supply me with tune points used please, for whatever reason it's not logging the afr input but I can see the voltage on the port.

I tried that tune it started and idle good, but as it warms up it leans out a little. when the fans kick in it gets a surge. what is the best way to fix that?
THANK YOU FOR YOUR TIME YOU ARE THE MAN!!!!!!

Sounds like you need someone to really give a hand. A91what is easy to deal with and good at what he does...if you haven't PMd him ready.

There are a lot if things that need to be done to get the car to operate correctly. He's been a huge help to me and many others. This thread is for quick advise. I recommend anyone new to tuning to actually let him take over your laptop and do what he does best. There are others here that can give advise and point you in the right direction...but honestly...the time involved through a thread can be overwhelming. He got me running in a few sessions.
