derp. missed this comment. not sure if this was also directed towards me, but I have only stuck by VT because I have put a solid amount of effort into helping them bring the software to this platform that I would be an *** to just bail after all their efforts. I also like their interface, but that's the developer in me lol.

I'm basically just trying to dial in the MAF calibration before messing with open loop fueling tables. For now, I've decided to just scale everything above 100g/s by a fixed amount, set the open loop AFR to 12.67 in all tables/cells and go see what happens.
The car is a stock series 2 (stock intake) with a mid-pipe fitted for track weekends.
Ultimately I want to end up with a tune for the track (w/ mid-pipe) and a tune for the street that optimizes AFR while keeping the cat safe.

In 2nd gear my car switches to open loop at around 150g/s. I don't have many closed loop samples from my logs over 100g/s though, so it may be that my results are being affected by latency of the readings or throttle tip in/out.

Some of the things you guys are doing with the maf table really make me scratch my head . I've tuned multiple rx8s and it's rare that I even touch the maf table . Only when LTFT is out of whack and I know it is unlikely that some fault is causing it.
I guess there are several ways to achieve the same result - the way you are doing it is the hard way . IMHO
, starting to give up hope. I sent an email at the end of last week for an update... no response yet.

There is a type in the notes - these were 4th gear pulls.

I'm aware of a couple flat out hard crashes with ME during flash that were all recoverable by restarting the flash.
One of which involved a lightning strike, fried hard drive, and power outage.

My logs show some very small gains in acceleration (1-2mph but at higher air temps) at the end of a straight. I also have new coils and lowered the car between those runs so this is not all from the midpipe which I have to conclude is not making a big difference. My main reason for running the midpipe is to avoid burning up the expensive catalyst on the track. Actually, I have put the cat back in for daily driving.
I will try and get a dyno run at some point, but making a back to back comparison is unlikely to happen. I do have an earlier dyno, but that is also before changing coils.
btw, your dyno looks very smooth and healthy - good to see, mine was not like that at the top end.
