Ignition cut in 3rd gear
Just a little context for this issue,
I just completed manual swapping my car. I have verified everything is wired correctly, and I have applied a tune. A copy of it is attached to this post if anyone is willing to take a peek.
The issue: Around 37mph/3rd gear/1,950rpms, the throttle suddenly cuts out.
Looking at the logs, the throttle position goes from 22% -> 5.9%.
The timing also drops, but I think this is caused by the throttle cut 48* -> 25.5*
Absolutely no codes on the dtc or scanner.
The two times Ive caught this in a log have been at 34mph/1,950rpms and at 37mph, 2,100rpms.
I'm thinking this is most likely the tune issue, but it could be a lot of other issues, seeing as I've just replaced the back half of the car entirely.
Does anyone know what might cause it to do this? Any ideas are helpful.
I think Ill try to get more logs with more channels set up.
I'm also going to reach out to a tuner to see if they can help.
p.s. the car ran perfectly before the swap, so I don't think its anything to do with the engine like knock.
Update, just in case someone comes across this:
The issue ended up being the torque management. I turned it off on the transmission side, but missed the engine section.
