Speed limiter on a 2007 Suburban

[zkeller]

A friend of mine has a 2007 Suburban. The speed limiter is set to 97MPH. He had me bump it up to 125MPH. I made the change and it still shuts down at 97MPH. The only field I changed was Speed Limiter #1 and #2. I left the source set to "GMLAN" and the third speed limiter setting I left at 186 in the limit and resume blocks.

Is there another setting in the PCM that works in tandem with the Speed Limiter setting? This truck is a 5.3 Liter with traction control.

Thanks, Zach

you need to set the source to calibration, otherwise it uses the speedlimit rx'd from the BCM.

Here's the stock file. Thanks for the info. I'll change it to calibration.
