2004 BMW R1200GS Power Commander PC V set up after exhaust pipe fitment – smoother, and nicer!

Posted July 1st, 2015 in BMW, Power Commander.

Generally, we would have preferred to remap the ECU of this GS rather than fit a Power Commander – but the owner didn’t want the ECU interfered with. Fair enough! But strangely enough 2 days after leaving our workshop he was in a massive thunder storm and thought there were problems with his Power Commander; his bike was coughing and missing, and wouldn’t re-start…

…we enquired if he had ‘EWS’ coming up on his dash and he said yes, so it was his built-in antennae that was causing the problems (a well-known and common issue with this era of Beemer). Anyway, we set up the PC V individually for each cylinder (and for his exhaust) and to be fair the bike ran well – a crisp throttle response, with the standard-issue harshness and bottom-end snatch elegantly removed.

This is an early 1200GS, and nowhere near as refined as the later models – and one thing the PC V does is actually bring them up somewhere near the performance of a more modern example.

A PC V and some Dyno time polishes up an early GS nicely...
