OBSOLETE: M84 is no longer for sale

The M84 is a versatile, race-bred ECU that is suitable for a broad range of high performance applications, including engines with up to 8 cylinders. It also suits rotary engines with twin, triple or quad rotors.

This new, entry level ECU is based on the advanced technology in MoTeC's benchmark M800, with a package of features to suit more moderate system requirements. It now includes on-board Wideband Lambda plus 1MB of data logging memory as standard.

Now with Nitrous Injection and 100 Hz max logging rate.

Install it as a stand-alone ECU or as part of a complete motorsport-ready engine management and data acquisition solution.
