Ok, so new to this LNF engine, and I read through all the how to blogs...still having issues, just wondering if anyone else has seen this stuff.
1st, the car is an Auto, and it seems no way to keep it in any set gear. I can't control it like some through the logger on/off functions, and inside the tuner the trans tab is completely blank. So about the only way I'm really able to make some comparisons is by doing a full WOT pull through all the gears then graphing it vs speed? Not sure if this is going to give me the comparison I want, it seems to be a bit all over the place.
2. This thing knocks like none other! Even with the completely stock tune on it, it's pulling 3-6* pretty much through the whole power band. I can't tell if this is phantom knock or if the car was for some reason tuned by Chevy this way? Anything I do tuning wise, seems to make it worse though. I've tried pulling a bit of timing, didn't help. I added fuel, didn't help. I copy/pasted the GMPP map, made it worse! From what the dyno is reading (not that I'm doing a very accurate comparison) the boost is going up, and the power is going down!
I'll jump to my other computers and upload the Logs/Dyno.
