Is camaro gas pedal drive-by-wire

[PsyDoc]

The system can be a bit buggy depending on the car. If you recall, Toyota had a recall in '07 (I believe) that involved the drive-by-wire system. The fix is typically to reprogram or reflash the ECM. I notice a lag-time is certain circumstances with my car. For example, if I drive at 45mph and take my foot off the gas and coast until mph hits about 38-40, then when I hit the gas again there is 1-2 second delay before the engine responds. There have also be a few of passing / getting out into traffic where the delay was really problematic.

More than a few Mustang owners have reported a "dead space" on the gas pedal where you may have to push the gas pedal down 3/4" or so to get any change in RPMs from idle.

I asked the same question, because I'm pretty unhappy with the DBW in my VW.

Nitpicky, but important: It's an accelerator pedal position sensor. The throttle position sensor still exists at the throttle body, at least on my VW.

It wasnt terrible but always annoyed me, it wasnt as responsive as my 98 z28, that has a cable. I havent driven any newer GM cars lately though to compare the mustang too.

1/2 second isn't so bad. I get up to 3 seconds of rev hang -- I take my foot off the gas and it holds the RPM exactly where I left it. My choices are to shove it into gear, dump the clutch, and feel like an elephant just kicked the car...or ease the clutch out very slowly, letting it burn off a bunch of clutch material. This is reported by others with the same model; some have tried to get it fixed by VW, but VW insists that it's by design. Who did they design it for?

The system on my corvette (08) works flawlessly. I'm sure whats going to be on the camaro will be the same setup. You wont even notice it.

negative, it does not nor would it ever do that, that would make it impossible to double clutch downshift while braking.

And yes I did that I my drive-by-wire 00 Vette all the time. The gas pedal does not shut off, and IMO in that car it felt as natural as any cable based pedal I ever had, so I'm sure 9 years later it still does.

You caught me. Guess I need a sexetary to proof-read my posts

gm drive by wire is great

VW drive by wire is very bad, i work on them and several times i found myself on test drives and pushed the gas pedal down and counted to 3 in my head before the car actually started to move

Any idea why they would program it that way? It's not due to technical or cost purposes, as far as I can tell. It seems to be entirely intended as a feature.

I can't imagine VW programming them that way. I drove a turbo beetle that had lots of turbo lag that almost got me t-boned! Were they turbo cars?

There's an easy way to prove it. Use an OBDII device to log accelerator position and throttle position. When they don't match, blame the programming by those smartass German engineers.

the vw's is a software issue, if the computer see's the brake switch on the brake pedal not fully released and the gas pedal pushed the computer freaks and it takes several seconds for the computer to catch up,, happens mostly if you drive 2 footed, and i do and so do a lot of people,, it can also happed if you drive 1 footed and are real fast to release the brake and push the gas pedal

it happens on the turbo and non turbo cars

also the if you are driving a vw and you touch the brake pedal just enough so the brake switch will engage, the engine will close the throttle and the engine will just idle

Driven lots of GM cars (LS2 & 3) and their throttle response map is a little slow and on Toe and heal changes the throttle is too slow.

BUT just get it remapped by a good tuner and then it is very nice to drive

Mine is flawless.

In my G8 GT I've had some delayed response issues, but I took it to the dealer for a TCM update and the lag is gone.

In fact I prefer it. Went from a Trans Am to a GTO and throttle response is much better with the drive by wire. GM knows what they are doing with this one.
