Drive-By-Wire BOOSTER (Home Made)

Read the actual question (again).:tsk:

i do not think you understand what you are asking.

you want the perceived throttle response to be quicker. but the problem is its "perceived." you said it yourself, the response is fine in neutral. so if its fine in neutral, then that means the engine is just perfect.

the delay you feel, from when you stomp on the gas, to when the gigantic hunk of metal moves is the caused by the automatic transmission. they are slow. they require a small computer module to run them. you floor it, it thinks about it, it decides you want to go fast, then it has to tell the transmission to downshift 1, 2, 3, or however many gears it is. each downshift taking up a longer time, which is why when you really floor it, it takes even longer. then, the gears are in place and it has to send its power through the torque converter, taking up a bit more time too.

in the end, the majority of automatic transmissions in this world are very very slow to respond. thats why having a manual transmission is considered more "sporty."

read my first response about throttle response chips. they are complete bogus.

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.

What kind of public High School you've got expelled from ?

^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.

You have the exact same answer from these guys:

Dude.

Brake clean.

he is talking about an automatic chevy tahoe.

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

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.

[Kershaw]

no.

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

^ 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 ?

[raafhimself]

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

[Gesucht]

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.
