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.

Good job Bill, Chris and all the software engineers involved. :worship: I am going to have quite a few people showing up for retunes now I think.

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:

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

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

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.

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

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

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.

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.
