Hi all, i have been lurking and reading this site for awhile now. I just received my hp tuners and i am going to be diving into my 2015 ZL1 that i had professionally tuned. The car has 2.5 pulley, headers, highflow cats, catback, cold air intake, flex fuel sensor, and aux pump. I have and need to install an aem wideband.
So i pulled my tune out of my car and i have a few questions i was hoping someone would be able to help me with.
It looks like it was tuned maf only so i know i will have to sort that out.
On to the questions
1. Does it look like the tune is PE raped? eq ratio gas is all one number but it looks like eq ratio alcohol bounces around.
2. Does the PE setting make it always in PE? It shows no rpm delay and only 15kpa min map
3. It looks like the tuner copied my high octane table to the low octane table. Should i just pull 10 degrees out everywhere for the low table?
4. LTFT idle cells threshold he has enable vss 318mph disable vss 317. What exactly is that doing?
5. On Knock sensor threshold min he had 50 for all but cylinder 1 he has 150. I am assuming this is a fat finger accident?
6. It looks like he set my main timing table to be alcohol timing and subtracting timing from gas table instead of adding timing for alcohol. Should I change this around?
7. Any other glaring issues with my tune?
I am going to spend some time setting up my scanner parameters tomorrow so I will be looking around the site to see what I should be logging.
I know I am asking a lot of questions and i appreciate any feedback.
