Learn Down Question
I have a '09 with a GMS1 kit and was curious if that completely removes the learn down from the computer? If not, is going with a tune such as Trifecta really worth the difference?
they say it does, but im not sure, but trifecta or hpt are quite a bit different power wise, is it worth it, yes, the power difference is worth it. I believe gms1 gives u 280hp and 340ish trq, trifecta and hpt, gives u something like 300-320 whp and closer to 400wtq I believe. so big difference. that 280hp on gms1 isn't wheel hp either. idk what guys dyno though may be close to that.

There really isn't forsay, a 'learn-down' feature.
The LNF ECM is torque based, & tries to meet the 'torque-curve' that is programmed, by whoever does the programming, be it GM , Trifecta , or your HPTuner programmer.
When the ECM is 1st run, after any reset, or programing change, the ECM will learn, be it up,or down, until it 'settles' into its normal operating mode. This happens rather quickly, as all the internal tables, are getting normal 'set' points, to follow the requested 'torque-curve', of the ECM program.
That being said, if your drag racing, try reseting your ECM, before a run down the track, it will probaby be your best run of the day, as the ECM is 'wide-open', trying to settle it's tables, into a normal 'set-state', of calibrations, for the 'torque-curve', that's programmed.
That's, why HPTuning is the best way to go, as the skys the limit, for programming, so that you can program, the best 'torque-curve', for you.
HPTuner software is a powerful tool, & dangerous, at the same time, with aggressive programming.
With just a few parts, a K&N air system, a TurboTech engine mount, a modified 2nd cat, lighter wheel/rotors, & slicks,
with a super E47.5 HPTune, I got a best of 12.39 at the track, with an automatic HHR SS.
It's a super DD, with this tune, even in the winter…
