"Reduced engine power"

[mikel]

the 93 tune in advanced is diablo tune.

CAGS should be disabled in the tune, can't hurt to remove the slp device.

If possible, try loading it with no changes, no tire or speed limit adjustment, to see if we can narrow this down.

Might be on to something, no reduced power message after Easy 93 tune with no adjustment for tires or removing speed limiter. Gave it a couple seconds then took a spin around the parking lot at work, no message, seems to be running fine, got up to about 4k rpm in 1st, will have to see what it does on the drive home later. I can try doing the tire and speed limiter independently to further isolate. I'm really not worried about the speed limiter anyway, if there is one its probably higher than I'll go anyway. The tire sizing is a small issue for now with speedometer correction and I'm planning to go a little bigger again next time, so I would like to figure that out. Obviously also want the tuner I paid for to work properly, appreciate the help.
Tune files below if you can figure out anything from this.
Thanks

Thanks for clarifying, we'll dig into this.

Well it ran fine on the drive home, will see if I can isolate the tire vs speed limiter issue when I get a chance.

We looked Friday and found which param it was, and its being fixed

yeah, if you disable the speed limiter setting, it puts it into limp mode.. have ran across this on all chevy SS vehicles I've done tunes for people for.. happens for intune and trinity.. if the speed limiter setting is set to disabled, it triggers reduced power mode..

[Brad02ss]

Yep, haven't had a chance to check in here in a couple days but got an Email and was coming to post back here- after adjusting both independently the tire size wasn't the problem, the speed limiter was.
Thanks

Could this be the same problem with a 2016 C7/Z06? Load the easy tune and all is OK. Load the advanced tune and throttle is in reduced power mode!
What does the speed limiter function do? Speed limiter is 203 mph in the OEM calibration.

what are you adjusting in the advanced tune?
Entirely different issue as this is a 16 SS with LS3 and E38 PCM, as opposed to LT1 and E92

Cooling fan.

I have a 2014 Silverado and I get the same message when I put the 91 diablo flex tune in the truck after a little driving the truck goes says limited power mode or something along those lines and I have to install the 87 flex tune or the stock tune. It happened once before when I turned off the DOD mode, but after reading this I will try it again but with the top speed limiter on and see if that works.
