Just wondering if i need to retune my Autronic ecu if i put on a fmic? Or will it pick it up and tune itself

Need a retune to get full benefits of a FMIC (and minimise lag)

The autotune feature *if set up* on the autronic - is well.. basic and still requires fine tuning.

Definitely worth getting a retune. Anything up to two hours on a dyno should be expected.

put simply, anything which will affect the way the car breaths, the speed of the air, exhaust or restrictions will require a retune. no ifs buts or maybes.
