Sweet! Now I can use one tuner for both my cars, and don't have to rely on Trifecta.

THANK YOU SO MUCH BILL!

"Very EXCITE"

Chris have you found anything in the code relating to the throttle delay at wot? Im loosing precious seconds during autocross

Firstly, thank you for the surprise, HPTuners, you rock!

And yes, the throttle delay is a pain, I see up to a full second between commanded 100% and actual 100% throttle

please email your file to support with a description of the problem. Sounds like they have enabled pedal or torque ramp limits which i beleive weren't calibrated in the early solstices in 07.

Its just all lnfs that I know of, drivebywire delay.

Here's what im talking aboot, at the bottom the etc pdl gets pegged at 100% but the etc dsrd slowly ramps up between 50-100%, it takes a second for it for the throttle body to fully open.
I can send my file if you still want it, its from a 07 gmpp gxp.

This is awsome news. I can put my wg rod back to stock now (some lower rpm mid load surge can be seen) and still boost 24 psi. I am anxious to try tweaking the fuel pressure in my car as well. Stock pressure drops off up top that is the first thing I am going to fix. Good job Bill, Chris and all the software engineers involved. I am going to have quite a few people showing up for retunes now I think.

Me first... for E85 lol... I at least want to get a place in line or a ticket with a number on it or something lol... They just opened an E station 5 minutes from my house... it's on like mother effin' donkey kong

There's also a boost cut on my '09 HHR SS auto right before it shifts. I'm not sure if it affects any of the other cars, but I get this in addition to the throttle delay.

Here's a dyno graph that shows the boost cut:

[Jaxon]

Does the throttle close inbetween shifts at all? Im assuming its a way to keep the auto trans internals from becoming externals lol.

[quickboat]

Nice, apologys for the inpatients and skepticism....

[BackyardTurbo_FTW]

Some other members have removed that delay by changing the TB itself. I haven't personally tried this but Ive found that delay at WOT isn't hurting anything either.

Im going to post a how to soon on how to tune the DAL table and get predictable throttle changes and boost under mid loads.

[Jaxon]

Did they change to another stock LNF TB or a different one?

[Pandion]

LS III TB like the supercharged guys were doing maybe? Or was it an LS IV? I can't remember.

[gmtech16450yz]

2.4L LE5 throttle body bolts right on and plugs right in. Tuning is def required, and it's tuning like what Nick is talking about, not something a lot of guys know how to do.

Hey Nick, hold on before you post up your "how to", I have something I'm thinking about doing.

[Jaxon]

Can you even do the tuning required for swapping the tb? I didn't realize the le5 tb would be an upgrade. I know the ss/sc guys use the ls4 tb off the gp gxp/impalla ss.
