LHU Standalone won't rev over 4,000

[kiwiracer]

Im running a LHU Ecotec (2011 Regal Harness, E39 ECU) in my race car. (It's a Miata). It's a new build, and we race next weekend. I have the car running great, but it won't rev over 4,000. I am not getting any DTC's.

I have read in the forums here about MAF ranges, also possibly that GM limited the first gear to 4,000rpm (or also when there's a Limp Mode), which I have been playing with.

Any ideas ?

Anyone out there with an LHU Standalone Tune that I could compare against mine?. Everything else is working as expected.

Thanks !!

Hey Guys, found the issue.. the PARK/1st Gear setting was set to 4,000 RPM. Changed that, and im good.
