Trying to learn HPtuners. The logs are showing the timing is off a few degrees from what I'm commanding in the tune.

Is there a table pulling timing that I'm missing? Anything else stand out?

Set up:
Stock LS1 short block
317 heads
LS6 cam and intake
80lb injectors
E85
TC76

Zero the burst knock retard vs rpm table.

Thanks Russ. I will look into that.

I assumed if there is burst knock, it would show up as KR on the log.

You need to log burst knock. Burst knock isn't spark knock, rather it is to PREVENT spark knock during quick throttle opening. Also on boosted cars burst knock can be set off when not needed. You could try and tune it by raising the threshold table.

Thanks for your help, Russ.

I think I have a better understanding of burst knock after doing some searching. I think I'm better off just zeroing out the table like you suggested. This little turbo lights up so quick, I think I would be fighting burst knock.

WHere were the 80lb injectors purchased from if you dont mind me asking? I dont remember seeing injector data in my box when i recieved my 80lb injectors. Is it a speed density tune?
