Hi everyone,
after I have bought me a second hand engine for my sierra I was curious about how to set my ignition timing on the standard ecu? The engine will run on lpg and a bolt-on turbo kit. My plan was to run the car as a daily due to the daily distance I make everyday.
I have heard that setting the ignition timing on the standard ecu is not possible but I am not really sure about that.
Can anybody help please?

Thanks in advance

Cheers
