Make the ol fuel table say 0.3 or so richer (ie subtract 0.3) for all cells over 5000rpm loads over 1 if you want to keep the rescaled maf values assuming thats where you now getting knock.

nope all knock on this maf rescale are now around the 0.9-1.1 load/2500-2900rpm buckets.. so I've reduced base timing B table accordingly and we'll see how she runs

iris had some upper RPM knock before the rescale, but I went ahead and reduced base timing B by half and no knock in upper rpms anymore

I have seen the OFT 91 tunes pull AM as low as .2 on my friends car.

Damn 91 octane!

I'm currently troubleshooting as well, I think I'm gonna run some octane booster for this tank and start fresh the next one. My last tank from Chevron gave me insane amounts of knock, IAM as low as .50 no idea what the hell was up as I was getting .95-1.0 IAM the past 2weeks on chevron.

Switched to Shell but I still have some Chevron left in the tank, so gonna start fresh with Shell I guess.

Do you mean .2 IAM or pull .2 from the IAM?

Yeah down to .2 IAM. I told him that's not good lol. He had raised his rev limit to 8k with out changing the resolution in any of the other tables. So that very well could be why.

8k limit! He needs to go read the oil starvation thread.
