Hey there
have a 1990 sapphire cossie 4x4 and am in the buildup process (engine,suspension, brakes) and have finaly got to the big question, what mangement system should I use
for the moment I have based this on a stage 3 tune setup, but am undecided on whether I should get a chip for the current ecu or get a complete replacment ecu setup, the two I have in mind are the MoTec M400 or an autronic based setup.

cheers hadyn
