How to adjust fuel scaling

[Yourbuddysatan]

Does anyone know a link or can walk me thru adjusting fuel scaling? I’m not sure how to do it and I think it is what I need to fix my LTFT and STFT problem. I can’t find a vac leak on my car so I’m not sure why I keep setting a light for 29E0. Read on other threads about changing the fuel scalar to fix it.

Thanks

Increase fuel scalars for more fuel (if going lean), decrease for less fuel if going too rich.

I know that needs done. I don’t know how to get into the tables to change them. Like can I use tuner pro? How do I connect to the car to even change them?

What tune are you using? Or are you stock?

I have a custom tune from wedge performance. Ever since I have been on ethanol I have got this code and my fuel trims are all out of wak. It sets super fast now like 20-30miles.

Did you retune for ethanol? If so ask wedge to fix it. If not you need to tune for ethanol.

Yeah. I did his flex fuel tune. I’m sure if something has to be altered in his tune he would have done it already. I must have an underlying problem I cant seem to find.
