Shiv,
Is the Timing advanced parameter the only determination of the gains to be had with respect to the big torque gains in the 2500-3500 rpm range?
Reason I ask is because I have knock events occur within those ranges and have pulled timing back to compensate for this.
This is a comparison of Stage 2 UEL modified vs Stage 2 UEL Stock:
Would the amount of timing pulled as shown in that image be detrimental to these gains or significant decrease?
I have also noticed that the Stage 1 Stock map vs Stage 2 UEL stock map indicates there is really only timing advanced in the 6400-7450RPM, is there a reason why there isn't more timing Advanced in regions prior to this, apart from the 4800 rpm range?
Thanks.
