Hi guys, has anyone come accross any tables/maps availabe to control the reaction speed of the electronic throttle i.e. the speed the blade responds to your foot. I'm in the middle of a tune that is going ok i.e. good timing, no KR or burst knock and it feels good in the upper rpms but feels a bit flat off the line and with respect to throttle response compared to a cable operated throttle body.
thanks
Further to my problem above here is a log and the tune, if anyone is interested.
Basically feels a bit flat on take off compared to other manual ls1's
I am also interested in this.... I'm currently running a cable throttle body in my ~2500 pound autocross / track car. I'm having trouble modulating the throttle just off idle... The weight of the car, the short gears, aluminum flywheel and solid motor mounts make it way too "snappy" I'm tinkering with making a new cam profile for the throttle body to open the throttle slower just off idle... but it sure would be easier to convert to drive by wire and program the opening profile to my liking.
Is there a table somewhere that I'm missing that relates gas pedal position to throttle blade % open?
Under torque management I always put 100 in all the cell of ETC TPS MAX. That should help, also try lowering or zero out Spark retard vs. torque reduction. I always zero out traction control System Retard vs. RPM.
DBW Throttle control is either through the TAC module (not adjustable) or on LS2's directly in the PCM on a separate controller (not adjusable).
If the car feels flat, check fuel & timing. Much can be accomplished by adjusting those. And use a wideband if you aren't already.

I have done an L92 conversion on a 6.0L in a Jeep, I am using the harness from the Escalade 6.0 and have wired it up to the Corvette 90MM throttle body. I can wire it to control the idle perfectly but then the pedal doesn't work. I then switch a couple wires and then the gas pedal works perfect but then it idles at 200rpm, I try reprogramming and it makes no difference.
Might take a different TAC module to control the 90 MM. There's a post over on performancetrucks.net about the parts necessary for a 90mm conversion on a truck. Check for West Coast Cylinder head 90mm conversion.

You need to buy the conversion harness part # 1X327100 for $69.95 This will allow you to go from the 6.0 76mm to the 90mm throttle body. You can purchase it from GMCOPO.com Good Luck!

I've got to try and return all the favors you guys have done for me!

What year model pcm are you trying to use? I think it has to be and 03 or newer for the TB conversion. The older PCM's had a seperate TAC module that wasn't associated with the PCM like the newer ones. You have to have the correct TAC module for it to work right and the 6.0 is different. EC_Tune is right.

Sorry EC, you asked this question already...............

sorry it has taken a little while to get back on here but I finally have more info, I have an 02 denali 6.0 computer. I did find that it is programed to only allow 350 lb of torque, and that is what it felt like, I would get to that torque and the throttle would back way down. I increased it to 640 lb ft of torque and now I get on the trans brake and raise the rpm and it gets to around 4,000 and then shuts right down and the gas pedal no longer works but now the idle works and idles perfect again. I kill all the power and then turn it back on and the gas pedal works until I give it some load again. I put the old program back in and then it works but not much power and idle sucks again.
So do you think the 03 computer will fix this and do I need a matching throttle contol module for this year too?
Thanks a lot.
Probably a P1514 code. Max the P1514 table and all's well. (you can tune that table later...)
