That was it. All good now. Thank you!

Ah, so all of them... Ha.
Ok, I'll give it a shot.

Which torque limit specifically?

Got a 2015 Z06 with a 2650 and Nick Williams TB.
The system commands the throttle to close to around 70% as it approaches redline. I've zero'd the accel threshold, and increased the driver demand...

Bump to see if anyone has an ideas...

Customer states that his oil already smells like fuel. It's definitely pumping it into the engine. The question is why...

I have not seen this. The injectors are going to max during startup. I don't see why...

Any thoughts?
The car did not do this when it was on the rollers. Only when the customer...

There was a TSB or recall related to cars shutting off from bumping the keys, or something of that nature. Maybe worn key cylinder?

MAP sensor was still wrong. This should fix that, and a few other things.

Control module voltage drops to zero. It's like the key is being turned off.

Those high minimum timing values are not helping it stabilize. But it's also a poorly scaled tune. Well, not even scaled, just lower injector flow numbers. Lots to fix for it to be right.

Raise the VE Maximum table under dynamic airflow. It's 20+% lower than you're GMVE values.

Looks like a possible ground issue with the O2 sensor.

Injector data is a mess, but I curious if something else is going on...
Do you have a log with injector pulse width? That would help see if it's following commanded.

Hitting minimum injector pulse. Not sure why it's set to 1.555 at 2000rpm....

I'm seeing 800Hz from the MAF at various times. It's only under decel, which is why you have a difficult time transitioning into idle. A larger MAF will shift the whole frequency chart downward, as...

It keeps tripping the Low MAF fail frequency. Lower this value to start.

Very lean. Or has a massive exhaust leak before the o2's

Talked someone into letting me test their ECU on this car.
Problem disappeared. Definitely a bad original ECU in the car.

Issues pretty much solved.
Now I just need to get a permanent ECU for...

Voltage across the ground wire of the PCM to the ground of the battery showed a max of 0.1v. No spike when the ECU commands different airmass values than those in the MAF table.
I took a video of...

Meaning that it is not a ground problem?
The ground is solid?

Checked voltage to positive, and to ground. Positive voltage was 14.5-14.6v the whole run. To the ground showed 0.02 to 0.1v over the run.

I checked resistance in the wire to its connection points. All between 0.1 and 0.2 ohms.

The ground is solid. Just checked.

To further illustrate my point...
Look at the airmass and inlet temp changes in these two screenshots from Dyno 05.
