This is the factory tune with the EWS immobiliser turned off.
7000rpm rev limiter.
Improved fueling and timing (designed to run 98 octane only) gives much better pickup down low as well as top end power.
Common M52 'rev hang' removed.
Vehicle Speed Sensor requirement removed.
Performance Tune for M50 manifold:
Same as above performance tune but mapped to suit larger M50 manifold.
