If as LWJ says, the ignition timing is adjusted for cyl 1&2 due to the inlet valves opening 10 Deg late, will having the ECU flashed by ghul overwrite these settings?
I'm just wondering out loud.... any ideas?
I figure the ignition is retarded on 1&2 on the std set up. Actually I'm sure the ignition is retarded on all the cyl. Between some revs in the first 3 gears for emissions. Ghul Motors remove this when the ecu is flashed. I wonder if that overwrites the delay on 1&2. If it does then that could be bad...
Thoughts?

Did this project actually happen? I'd be curious how much smoother the motor would be with stock, but symmetrical timing.

The thing is that valves are opened by the cams, not the ECM.

if I could afford to do things like this I absolutely would !
