I'm trying to wrap my head around why you'd want MHD linear, then add BMS pedal. (that sounds more confrontational than I intend it to).

Personally, I'd ditch the pedal tune. Making you think your car is faster because 30%->75%? No thanks.

MHD linear is really nice for me. With the stage 1 OTS power gain, I find that the throttle action isn't that much different than stock, just that the last 50% is still even faster. I love it.

I tried xHP tonight - doesn't work properly on my car. A lot of what's in the 2.0 map update (see all that mention of non-DEC cars?) I believe is because of me.

I flashed xHP and I can see their improved shift points (e.g. RPM vs. throttle angle) but every shift is now the slowest, smoothest, mushiest program. Same for D,S,M, and for stage 1/2/3. I *DID* notice that the TC action is much nicer. I did some neighbourhood four way stops on xHP Stage 2 and it "launches" way nicer. No pause-then-lurch etc...

Fortunately a flash back to stock map and I have better shifting again. I didn't have to uninstall xHP altogether. I've contacted them and we'll see what I get. Since it's just the map and not the code, I'm presuming it can get fixed.
