: : you will have to ship your computer in to JimC to have him upgrade it. Insure it well my son :) (for the trip through the delivery service)
: : JimC - More Aggressively tuned.
: : Dinan - BMW warranty safe, can do it at a BMW dealership.
JimC does a lot more than just redline, speed limiter & timing. it also adjusts the fuel/air ratio that allows a richer mixture - therby a more advanced timing (no detonation) throughout the entire rev range. not sure about this one but it probably also alters the cam timing.
i've just had teh JimC reprogramming done on my MZ3 (taking into account the cold-air intake) and the thing screams. definitely money well spent.
