Throttle Response: DE/HR vs VHR

wstar found out that disabling electronic throttle control makes it a blast to drive the car because the response is very fast, but you lose the safety features like VDC, electronic rev limiter, and S-Mode. It caused his 7AT to shift funny.

If you want to experiment, you can completely disable Electronic Throttle Control. At the bottom of the list of editable stuff in the UpRev Rom Editor, there's an "ETC: On/Off" setting. I've set it to off before, and when you do that the car very literally maps 1:1 between the gas pedal and the "throttle" (although still, I imagine it's more VVEL than the manifold butterfly).

Throttle response with ETC Off is awesome, the problem is it kills a lot of other functionality on the car too. You'll lose cruise control (who cares), you probably lose the (safer) Throttle Rev Limit, having to just rely on the fuel cut rev limit, and most importantly you lose Synchro-Rev-Match.

On a track 6MT car, for someone who disables SRM to heel-toe anyways, ETC Off might actually be a viable option. On my 7AT it's a no-go though, the transmission can't execute downshifts properly without its own equivalent of SRM.

Yup... I miss kicking the tail when I tap the throttle in 1st as it quickly revs to 2k RPM. It happened when I test drove my friend's HR. Maybe that's too touchy of a tip in, but something close would be nice.
