I'm trying to get the tune dialed well enough to venture outside the garage to take some logs and start working the MAF in forced open loop, but at this point, I don't dare to do that, as the engine does not want to start after it is up to temp (starts great when cold though). I was able to keep it from stalling, which was progress. And yes, I am very new to this wonderful world of tuning via laptop. - This is my first go at it actually.
If I could indulge your generosity and patience, I'd be most grateful for some input / help. I have been studying till my head hurts and can navigate HPT well enough now, I believe. (finally figured out how to get the histograms to work, which now I feel foolish for asking earlier).
08 Z06 - ported heads, cam has 18 deg overlap (235/255 113 646/670)
I have been playing with start up air flow (raised it in increments up to 40%), and wasn't making much progress, so copied the start up air from an LPE 660 tune in the repository to see if that might help, as the cam / heads are similar to what I have, but it did not. I suspect I need to work base idle timing a bit now after comparing a few different tunes to what I have now. I am starting out with a base tune that not stock as I bought the car with mild cam installed.
I also suspect I have a miss. I installed new plugs (TR6 @ .038") and new wires (MSD). The wires seam to be locked well, but I'm terribly impressed with them....
