Smooth Throttle for UpRev

I only tried it for a quick trip down my side street and back, and the 7AT was not very happy about it. It didn't rev-match at all, so every shift was clunky and horrible. At the time I didn't even think about trying to manually rev-match with the gas pedal on the 7AT heh. It didn't try to stall though, it just engaged really rough, like someone dumping the clutch without rev-matching at all on an MT.

Argghhh... I want to play with it, but I'm worried it could cause damage somehow... I'm trying to think logically here...

What damage could possibly be done without the additional throttle control to mitigate shifts? Nothing?

If it just shifts hard, but runs correct line pressure (possibly defaults to max?) then I should think it's safe to play with, no?

Beats me, you're on your own there

After trying some of the suggested maps in this thread, I pretty much just turned ETC off and couldn't be happier... It feels sooo much better.

I don't miss SRM or Cruise Control (don't have the buttons to use either anymore) and the boost in response would be totally worth it as a non-DD car.

Dang it... I'm just going to have try this now.

That is the benefit to owning the tuner version

You can tinker and test and try stuff out until you've got the perfect combination that works for YOU.. and DON'T have to shell out $150/hr for dyno time

Great thread man! when I do some more data logging and what not with upRev I will take screen shots

I'm with kennys370 on this. Keeping the engine cool makes the most diff. The fan mod works, with an aftermarket (proper if you will) oil cooler, it is gonna b perfect

Finally tried it.

Honestly, felt no different to me than my tuned map, and in regular Drive, a bit less responsive.

Down shifts were a bit clunkier, not enough to be unlivable, but enough to make me think it's not an improvement.

Anyone who likes ETC off, try my throttle map instead -- feels snappier to my foot anyway.

Using ETC off with an Auto is a bad idea.

ETC off with a manual, is heavenly.

You definitely shouldn't use ETC off with an auto, it could put a lot more stress on your transmission, those clunky downshifts aren't good for it.

Also - Flashing wipes learned fuel data, so you really have to drive it for a bit before making the call on whether or not it's more responsive. The engine will definitely be sluggish and soft until it gets some trim data saved.

D'oh -- well only one downshift was clunky and under very low load, so hopefully its fine

If it follows TPS, it should be a linear function, and feel similar to the "smooth throttle" map. In theory the "driving force" value should enable you to tune it so it can be more responsive and peak faster, although it won't be linear anymore.

Oh well, guess it's all up to the individual driver.

^ That is, of course, definitely true.

It's not really about the throttle following the pedal in a linear fashion.. I mean yes that's good and what you want, but really it's the reduction in "processing time". There isn't that split second delay while the ECU calculates throttle position based upon user input, load and RPM. It just goes where it's supposed to be.

Also, it means VDC can't close the throttle. All it can do is apply brakes to prevent spins. I actually did a run by accident at my last AutoX with VDC still on and it was faster than the run before it...

wstar · 08-22-2012, 01:11 PM

You still want VDC off though, otherwise it's patching over stuff you should be feeling and correcting for yourself (and there are some corner cases where it could really upset the car and spin you out of a corner by tapping the rear brakes at a really bad time).

Sh0velMan · 08-22-2012, 01:33 PM

Oh definitely. Was just interesting that it was hands off enough without ETC that I didn't notice until well over half way through my run.

Hi, this is all too confusing to me. Firstly, I can paste the 2300 curve data from your first post into my throttle table? I have K&N intake, stillen headers, sport cats and akropovitch full system. Secondl, after pasting this in what will change about my car. Please, explain in lamen terms.
