Currently tuning and running into something weird. If I go like 90% throttle it revs up just fine. But if I go all the way to 100% then it feels like fuel cuts for a second and then comes back on. Is there a setting somewhere that would do this or do I just need to work on my tune?

Matt,
I have an ms3+ms3x and can't find the acceleration wizard that is mentioned in your documents. Is it only on certain firmwares? I have tunerstudio beta.

I seemed to have fixed my problem, definitely running better. Here was my original TPS accel "curve":

And after some messing around:

It is working way better, and no more lag when accelerating.
Attached my new log file.

42% threshold? that can be dropped to like 5%.
actually it can be zero and you just tune the curve correctly.
I'm assuming right now your tip-in is twitchy/rough as hell.
although, is that plot while you are idling? that's some noisey-*** TPSdot.

I'm actually basing the tune off a map you posted in another MS3 build thread combined with Westfield's map. Do you have a current tune I could pull some settings off of?

This is what I came up with that works best for me. I had to ramp it up higher to get rid of some lean conditions. And then blend in the MAP accel settings to get it to add fuel when letting off the clutch without the gas. Any suggestions for fine tuning this.
