Has anyone tried relearning the ECU ?There was always a lot of talk about adaptive driving and how you can reteach the ECU after a reset. Back in the Day with the AMG’s we used to put in sport mode and paddle shift to 1st gear and hold the paddle and keep at a high rpm to try and have the ECU adapt to the higher rpms . Also the fastest we noticed were runs in sport mode and launch in first and let the car shift itself .

How do you figure? They still haven't provided any proof. No screenshots, videos, anything.

What they're doing is essentially making an internal piggyback inside the ECU instead of outside, and it's still not fully functional.

Who knows what they really can or can't do.

I don't think this is entirely accurate. I've spoken to them several times, what they told me about cams is it's not that they "can't tune it", it's because of the new neural network stuff (anybody that's tuned an E90 truck would know about this), getting the VE calculations correct with a cam is going to be very challenging if not impossible since some of that stuff is done by AI internally at GM now. Given their priority on supporting emissions compliant parts, cams are about the lowest priority for them since none of that stuff can get emissions certification anyway.

They claim to have full calibration access, but of course without seeing their stuff we have to take that claim at face value. But at the very least, publicly, they're involved with ProCharger and Whipple, and in the latter case, they're distributing Whipple's CARB EO calibration, so at the very least they've managed to figure out how to stuff all the parameters in there that Whipple specified on their EO application...

I still have my Procharged C7 and after my Florida tuner stated hell NO for adding a Procharger to my incoming C8 … something is going on.
Trifecta … ???!??? What are they doing well ??
^^^ still biggest question …. HP is not equal to time slips or MPH on the C8’s at the track. It’s NOT street tires vs drag radials that would have or should have made it happen. Something is wrong
