anyone got any experience with motec ecu m4 pro
are they any good ?????

Motec is about the best there is. Not sure the system is entierly necessary for a 7 though. Emerald and the like are probably good enough and much cheaper. A mate of mine deals with Motec and swears by them but he is an RX7 tuner!

Yep Motec is an awesome ECU. Dependent on model (M$ pro etc) you can have anti lag, launch control, traction control... the works! As said above maybe a bit overkill for a 7 though

Mate had a Motec ECU on his Mitsi Evo powered grasser a few seasons back but his engine was worth twice what my whole car has cost!! They are the nuts but you would probably only notice a real difference if using in motorsport.
