ProCharger Tune

Well, the tune was perfect on the Ignite Ethanol he tuned the car on.

But once I went to Speedway pump E85, it started leaning out.

Part throttle driving like grandpa with a toe on the go-pedal and if it got about 2k to about 3200, I could hear the exhaust breaking up.

As more E85 went in, I eventually heard the lean pop once in a while and got KR of almost 2 degrees.

So we're working on the alky tune again.

Just changed this to 5 across the board:

It's better because when I accelerate aggressively PE kicks in sooner helping it not go lean under boost, but it's not a fix for the part throttle slow acceleration problem.

It's that real light throttle acceleration that is going lean. :shrug:
