Electronic throttle control sucks!

[chrisj6]

Ok, going from my '99 Silverado to '04 Avalanche, I noticed one major thing. The throttle response on this thing sucks! I know that it is a bit heavier than my Z71, but the response just isnt there. It seems like when I jab the throttle, it takes about a full second or so to start responding. I have removed all TM except the injector disable when traction control kicks in. The ETC max throttle percentage table is maxed out, so I know that is not limiting it. Does anyone know of anything i can change in the tune to work this out? My part throttle timing I know for a fact is maxed out, and the AFR is perfect. Anyone!?

to me it seems too jumpy with the e throttle control. i think u can FEEL the throttle better with the cable. idk how to fix ur prob, just thought id concur with u on this issue.

I dont know what all allen did but he made my truck feel awesome.

Yeah the power is definately there, these things were pigs from the factory. But its only really part throttle I am feeling. The torque is there I can feel that, but its just the initial response when I tap the throttle.

i like it. although i am lighter, lol...

I personally don't like it. But I think the lack of balls from a dead stop maybe the torque management.

Mine seems fine to me. But I also went from a bigass Z71 with 4.8L cable to the SS with electronic. The only thing that I notice is its touchy. When I let friends drive my truck, they always have to get use to it, like when they hit bumps and stuff.

I have taken every bit of TM out of the tune. Transmission and engine. There is no TM at all limiting this thing. Maybe its just a heavier vehicle and I am having to get used to physics! Damn Science!

I got it figured out. The throttle is still a bit jumpy, but I raised the converter lock and unlock by 10%, then modified the verter unlock and trans downshift speeds a hair. The trans is much more consistant and the hesitation is all but gone. I'm gonna have to chalk this one up to the converter, I also set the converter maximum to 98% and min to 90% to eliminate slippage. Truck is much much more responsive!

I accually do not mind the electronic throttle at all.Send me your currrent tune man.
