ECT cold spark on supercharged 5.7

[Shooter_tech]

My 17 Ram 1500 has a whipple supercharger. Runs great but when the engine is cold I get a fair bit of knock retard under normal driving, up to about 6-8degrees. Once the engine is at operating temp I get no spark knock. I was looking at the tune file and noticed the ECT cold spark table is zeroed out. The factory tune file shows it adds timing on the cold spark table. Anyone have any experience with the ECT cold spark on supercharged hemis? The reference shows -64 to 64, but not sure if thats C or F. As well the hot spark table shows the same reference, So I am not even sure if that is actually the reference. Any ideas?

On my 15 Challenger 5.7 the cold spark is same as stock along with ref temps and I have no knock issues. BTW my stock and original SC tune are posted in the repository (2015 Challenger 5.7 manual...under Casper).
