94 - MaxxECU internal error: Slave CPU error

Scroll Prev Top Next More

Somehow the main CPU cant communicate with the secondary (and slave) CPU on your RACE or PRO.


Note: Everything on connector 1 on your RACE/PRO will work as normal, but everything on RACE connector 2 (E-Throttle, EGT etc) will not work.

The unit must be reprogrammed, contact your MaxxECU dealer.
