Different people with different requests – when it comes to an ECU remap no two are ever the same. The owner of this RC8R (we also did his SMT which he took to Spain with his wife and loved) spends a lot of time on the track with it, and brought it in for much the same again, with one request; “don’t lose too much of its liveliness, but get rid of the snatch…!”
All RC8Rs take time to remap, and there is no shortcut to getting a spot-on power delivery. We sorted the fuelling first relative to the bike’s exhaust – and an important note here is that if you’re fitting pipes to one of these the fuelling at the bottom end is changed dramatically, leaner by 18% – and gave it the extra fuel it needed.
Having done that we took a look at the ignition map and then the transfer map from the manifold air pressure (MAP) map to the main running table, and this is where we worked to take away the ‘switchiness’ while maintaining the engine’s urgency. A careful balance, but worth the effort.
This RC8R lives on the track – and now has the throttle response it deserves.
