I need some help please. I've been working on my tune, its a 2 bar SD, plan on running 14 lbs of boost on my 5.3L. The problem I'm having is my timing table is not matching the log and I can't figure out what is adding timing?

Any help would be greatly appreciated.

Thanks!

Not sure if this is it, but check your Map sensor offset. I did a quick search and found different recommended numbers than what you have inserted. The map sensor offset is found in engine diagnostics/airflow/map sensor. Hope this helps.

Other than this, I don't see anything else out of place with a quick look at your tune.

There's a whole raft of timing advance and retard adders,
you should try and log them all one time so you can see
who's being busy. Then you won't have to guess.

Anyone know the data for the old school brick 2 bar map. I have an accel but no data and although tuned, I feel its one of the reasons I have had trouble tuning it.
