E38 LS3 Camaro Single turbo SD mode timing issues.

[T0nydat1ger]

First off.

2014 Camaro SS LS3
78/75 turbo
229/235 comp cam
950cc injectors
stock fuel pump/ i have a ZL1 just havent installed it yet.

I know my tune is a lil jacked up. Im still learning. Cant seem to figure out why my spark is dipping randomly. I removed 5 degrees from both high and low octane tables and set high rpm and high g/sec in the tables to 10 deg.I checked for loose grounds as well (kinda lost on how to adjust timing advance with SD )I disabled spark smoothing and i even adjusted the idle tables bc i believed the car was using timing from those tables at WOT.

That's an odd tune.
You've disabled the MAF sensor (but forgot to zero the test delays.)
You've also disable the VVE tables by setting the dynamic airflow to be enabled above 100rpm.

The timing tables need some work for sure. You need to work on smoothing the timing from low boost to high boost.

Here's a tune that I did a few months ago on a similarly modified 2012 Camaro. Maybe it'll help give you some ideas for your timing table.

I never saw over 160 kPa on the datalog. That's only 8.7 psi boost. You can run a lot more than 10 degrees timing at that boost level.
