C6 Zo6 with HPR 468 N/A_light throttle Knock_Help

[N/A Zo6]

Any experts have any suggestions as to why I would be pulling 6-9 degrees timing around 5000rpms while shifting through the gears? The log attached is running through the gears as I was getting on the highway. I could hear pinging coming from the engine. Running 93 octane with 11.8 compression. Motor is a new HPR built 468 NA with Brodix 273 heads and MSD intake and NW 102 TB and 2" AR headers. Another note motor made 650HP and 562TQ on Dynojet, I think the torque should have been around 600-625 based upon others with this combination. Car drives OK has some surging in the 2000-3000 rpms range. I attached the latest tune for review. I also attached a 40-130 pull to verify AFR looks to be steady around 12-2-12.6.......

Hi there - I've had a look at the log. Fuel trims look ok, did you check with wideband at that point? If you heard it as well and AFR is ok, just pull a little spark in that region.

Even though your're part throttle the big engine is still pulling a decent amount of load at that point. Looking at inj pulse width i dont think you are commanding any enrichment (PE), maybe consider that.

Interested as I`m about to assemble my HPR 468!

it has too much timing or you have it too lean for the amount of timing you have in those areas. pretty straight forward.
