My first attempt at tuning.
One thing: i couldn't get my Airflowperrev down to 0.28, no matter how much i adjusted the sliders the lowest it got to was 0.31 so i left it there.
Feedback welcome

Looks like an idle log to me. What is the question?

Why is your fuel global so high? It should be more like -55% and your fuel trims are adding fuel which would make sense since you have told the ECU you have bigger injectors that you have.

The WB Data doesn't look to be switching at 14.7:1 which would also throw off your fuel trims. Are you sure that the logs match your gauge or that you have the right switch point for NB simulation?

My question is how does it look? Lol. I'm new to this.

I had a buddy tune my car the other week but I wasn't happy w how he did it so I attempted to put everything back to how it is suggested to be based on ecmlink videos and threads.

He may have adjusted my global fuel but I havnt touched it. I'll take it to -55%.

My logs do seem to match my gauge, but what is the right switch point for NB sim?

Also why won't my airflowperrev go down to 0.28? I've played with the MAF sliders and can't seem to get it down below 0.32

The switch point will vary depending on the wide-band you have.

i adjusted my WB switch point from 2.49 to 2.43. not much of a difference. i adjusted global fuel to -53%.

started driving it and everytime i wanted to boost the car would fall flat on it's face. im not sure if its a fuel setting or a boost leak. I did a quick boost leak, didnt find anything so im gonna do it again with soapy water.

Another thing is after rev the car would either die or drop down to 200-300 rpm. Threads suggests i take out my IAC and clean it up.

My question is, do these symptoms have anything to do with the tuning? or is it simply these minor issues of boost leak and cleaning the IAC?
