Trackhawk VVA LIMP-IN
Hi guys,
Having an issue with a 2018 Trackhawk, 2.85 pulley, 180 tstat, demon injectors (MOPAR 5038838AA).
Using the hp security cable.
Once I installed the new unlocked ECM and the upgrades, the car instantly had code p0600 serial communication.
I used the demon injector and fuel rail psi settings.
I must have adjusted something that has corrupted the tune.
See below for update, issues resolved.
Disabled code as per tech support and found a factory hardware issue with spark plugs.
However i want to know what vva-limp in PID for fuel cut source means.

I set spark to 0 degrees and played around. STFT on both banks when boost kicks in is within 5% now, 11-11.5 aft when it faults, however the engine still feels like its cutting out. I think its just spark plug gap, small detail overlooked.

Found the problem with inconsistent spark plug gap and 1 of them was actually 0 gap.
