I've got this tune about 95% there. Running very strong and driving like stock. I'm seeing a bit of a weird spark reduction under half throttle that I can't figure out. Can feel a little kick in the pants when it returns to commanded advance around 4k rpm. It's up to 8 degrees below commanded at times with no KR and I can't find any modifiers that are contributing. Is there any way to log what modifiers are active? Anybody have any other ideas on this?

It’s tq MANagnent advance!! Log it and confirm and I’ll tell ya where it’s coming from
Ben you nailed it. Torque management advance is the culprit. It's actually fairly difficult to get to happen, very specific set of parameters to trigger it so not that big of a deal for overall drivability but I'd still love to get taken care of. I don't see any table labeled for that. Would you mind sharing the fix?

I’ll tell you how to fix it without exactly telling you ;)... gen 5 is Big business for me, and you’re somewhat local to me and these “shops” most likely read everything I write ha and use it for self gain ha..
But it’s my nature to help people..
You’re tune is telling the ECU to pull power through Tq management advance, notice what throttle angle it’s doing so and commands more Tq, this will fix the problem
Ben, there are few throttle channels, which one should we pay attention to and should it be reading 100 at wot??
Accelerator Pedal Position and Throttle Position (non SAE for each).Quote:
