So couple of things, I've updated the map pack. IMPORTANT: note that there are two 1x8 maps which are marked "wot throttle bank 1" (and 2)

THESE control your WOT fueling, NOT the 1x11 map that I first suspected.

Second, because I'm feeling generous, I'm posting my finished tune if anyone wants to try it out. It's meant for catless downpipes, open exhaust and a true CAI at 3500 ft elevation.

Bear in mind that this is a narrowband setup, so you'll likely have to adjust your fueling a bit.

However, I have made it so that any throttle input more than 30 deg will command 12.5:1 IMMEDIATELY!!! This is great for transitory situations.

In any event, I may take my finished tune down sometime, but for now, In keeping with my "No sectrets" policy, I'lm going to post it and see if anyone wants to give me some feedback.

Not sure that there's much to change, pulls like a raped ape, timing's good and AFR's are spot on

AAANNNDDDD this is how you learn to tune an M5.2.2 Porsche pretty much completely on your own....

Lol, yeah I know that I'm breaking my arm patting myself on the back. But I think that given how little info there was on how to do it, that this was a pretty monumental achievement for me Smiley

How similar might this be to the BMW M5.2 DME?
