2015 ECS supercharged C7 high and low octane spark tables look the same

[ThunderDan74]

I can’t imagine this is a good thing. I had someone (a forum member on here) do a tune with EFI Live that was supposed to get rid of the throttle lag sometime ago. I should’ve monitored it but I didn’t I’m a noob. About a year and 20k mi later, I installed a supercharger and had it tuned thinking the tuner (using hptuners) would sort out anything wrong with the tune. Then I started monitoring for KR on a Torque app. it was knocking pretty good under heavy acceleration below 3000 RPM. I brought it back to the tuner but of course the car decided to behave like a good boy. That tuner ended up pulling a few degrees out. But later it started showing knock again of course. So I started looking at the tune and found the high octane and low octane spark tables are the same values. When I compared to the original tune I saved of course they are different.

The guy I let tune for throttle response changed it so they are identical and the guy who turned it on the dyno for the supercharger changed the high octane table but left the low octane table matched. What I’m thinking is the old adage if you want something done right do it yourself but you have to learn how to do it right yourself in the first place so I’m in a catch 22. And I’m losing trust and the guy who did the dino tuning.
