To remap the ECU of the BMW S1000RR we have to remove the original map completely and send it to our software suppliers in Germany. We’ve found over the years that every one of these bikes is completely different, and you get a load of problems if you rush in like a bull in a china shop…

We do also makes some physical changes, like switching the exhaust valve off, lambda and SAI.

In Germany they switch off everything in the map that we want switched off. The map then comes back to us, we upload it and run the bike to make sure everything’s OK. At that point we can start mapping the fuelling and ignition. The owner of this bike had fitted an Akrapovic can and K&N filter, and generally in these cases the lack of bottom end becomes obvious and once the engine’s hunting for fuel the fly-by-wire throttle starts feeling very snatchy.

Top-end power is all well and good (and a good one makes 196bhp!) but most riders notice a horrible bottom-end more.
