Drive by wire lag????

[Dennisn]

Anybody experience any lag in response. I'm talking about getting on it wot then letting off but the car doesn't for a few milliseconds. It's happened to me more than once. I've talked to a few others that have had the issue.

It definitely doesn't feel as responsive to me as a cable driven throttle like I'm used to from the terminator, but I notice more of a lag getting on it than letting off. I don't know if it's a true processing lag in the system or if it has more to do with making sure all the variable cam timing stuff is where it needs be to do what I'm commanding.

I almost put the car in the wall the other night. Scared the shit out of me. It blew the tires off at the hit. I let off but there was few milliseconds lag which felt like forever.

if there is any lag in a drive by wire setup it is microscopic, you wouldnt even notice it.. if you let off and you notice a delay its either in your head or you have issues with your car. On the WOT you can notice a tad of a lag especially untuned where the car is calculating and commanding timing depending on the speed in which you slam the throttle.

Dude what makes you so sure. I've talked with a local tuner that's witnessed the same thing. I honestly think it's just the nature of the dbw but believe you me it is real. i can see on the log the desired and actual and there is a difference. Now looking at the log, the difference I can't see how someone could feel it being we are talking milliseconds but what I've experienced is real and I would most certainly bet it is not something wrong with the car.

Mine will open the throttle blade gradually - I have NEVER spun the tires in my GT - the car simply will not do it, the throttle does not open fast enough.

ok your car keeps accelerating when let off. sorry for you luck.. mine does not

On early tunes, I have the decel hang. I had to blip the throttle to get the throttle to close. If you have a log, I'd be curious if the log would show pedal vs throttle position.

All in the tune, there are aspects of it to control how fast and slow the actual throttle moves, from stock it's pretty small but can be lessened even more
