The problem is the whole scale moves a bit. So if I need 18 to produce 3% accelerator at a fresh flash, that 18 I put in the tables won't consistently produce 3%.

Unfortunately, the values are not fixed. They tend to wander off the more miles you drive. So if zero is e.g. 15 on a fresh flash, it might be e.g. 13 after driving the car for a while.

If they check if you have the original tune, then hex editing defeats the point as the tune will appear to be modified.

Better would be to flash back to (old) stock, unmarry the OFT and let your...

What's problematic? It retards 0.69 deg - that's next to nothing. If you want to tune your car to have no FBKC and no FLKC you are going to de-tune it immensely.

I don't think there is a reason to use the stock tables. I will almost guarantee that all you have to do is lower the cam to 38 or 39. But not just where the problem is. Use it as a max in the whole...

Try lowering the intake cam to 38 deg as a max all over. It's speculation, but maybe it tries to drive the cam to 40, but as it can't, it reaches some kind of physical stop and "give up". I don't...

Do both cams otherwise reach the values in the AVCS low detonation tables (except where it VVT if off)? E.g. are you asking the intake cam for 40 deg but it only reaches 38.xx?

Load is not "boost".

Load = g/rev = (g/s*60)/rpm

g/s = MAF

Hence:

Load = (MAF*60)/rpm
