Hi All,
I'm absolutely stumped what is causing this. I've just put a Turbo on my LS, wrote the 2 Bar OS and built the VE Tables. When I put it under moderate load the ignition timing drops right out! I initially thought it was burst knock retard but it is pretty much on 0. Could you please have a look at my tune and log and see if you can make out what is doing this? You can see it around 10:26:00.
your torque dosnt like to go over 500nm so it could be torque management u still have alot of that still in use and with the boost it will easily go over its limits, max out all the gear tables and see if it helps and the [ecm 12820] also max all out, make maf fail high 2 and low 1 also and the 3 maf dtc's mil on first error
