Now that my 04 R has 4000 kms on it (I know, weird story for another post ) I finally floored it and expected to get about 280 kph (as per BSR's Stage 1 PPC), and definitely 250 kph. I didn't, so I figured I too have the 210 kph (130 mph) limiter, as that is the top speed I managed. A couple of quick questions on it:<p>a. Is it software number 8645433 that solves the problem? There were two s/w # mentioned in the older threads.<p>b. Has anyone else experienced the same problem, having had the ECU upgraded on their car? I mean, I would think that since BSR's PPC lifts the stock limiter from 250 to 280 kph, it should also lift it from 210 anyway, right?
