Drive-By-Wire BOOSTER (Home Made)

[Gesucht]

The tahoe is stock and only 2 years old, with barely 20k miles on it. Its like not there... when it suppose to be. It gets pretty lame for a moment when you drive up hill, or when you make a quick left turn ( yield on green).

Really. SO you step on the gas and then there is a lag? Hmmm.... This is a Tahoe you said?

Yes, but i'm not trying to get this tahoe as quick as e30 or other fast car. Just a good reasonable throttle response, not more HP or Torque.

That's more than likely the automatic transmission being lame, not the DBW.

^ OP read this again. it takes a few moments for the AT to take your throttle command and respond with the appropriate gear change.

That makes sense, consider if the throttle response is fine on neutral or park.
Is there a less expensive way to dial that sensor ?

[Kershaw]

no.

and it is not a sensor. it is the transmission.

[george graves]

^shut up. It's the sensor. I'm 100% sure of it. I think you should soak it in water and see if it improves it.

Brake clean.

Honey.

[Mossman]

you have to figure out if it's a carbon based or some other kind of sensor. One of them will operate faster in intense heat, the other in intense cold. Just try both, first douse your gas pedal with liquid nitrogen (sneak into local high school science lab and steal it they won't mind), If that doesn't work try the old propane torch. Report back.

DBW on my brothers 540i/6 is a bitch, laggy as hell when trying to rev match quickly. its the same on my uncles e46m3 when not in sport mode.

bmw likely made it that way to make the driving experience smoother and more comfortable, like they did with the clutch valve.

he is talking about an automatic chevy tahoe.

WHY he thinks his AUTOMATIC CHEVY TAHOE is a sports car is beyond me.

Read the actual question (again).:tsk:

You have the exact same answer from these guys:
