ACR-X ECU

[ACRucrazy]

Does anyone know anything about the ACR-X ECU?
Does it differ from the standard Viper ECU? How does it differ from the MPP?

I recall reading a blurb how its different, but I can't find any specifics.

I'm sure it's not the same as a street Viper including ACR. For off-road use only, non-emission compliant, no cats, maybe higher rev limiter, they probably program it for BALLS OUT - FULL BLAST - TRACK MONSTER.

The ACRX computer is a track specific calibration that runs open loop and requires high octane fuel. Calibrations are often changed by SRT for differing tracks and elevations. Best computer for the club racer or bolt on performance Gen 4 would be the MPP controller. Be aware the the MPP controller needs 93 octane fuel or better.
