| Having had experience with both, I'd say there isn't much in it performance wise. Both will need setting up properly on a good dyno operator to get the best from. The off-the-shelf maps are an approximation at best. I found that it's quite a bit easier to find a good dyno centre. FIM mapping support is harder to find. The FIM ECU's on the new bike allow you turn off immobiliser thingy and is good when you're racing as it also allows you to raise the rev limit. It requires no additional wires, etc. On the other hand, the PC is dead simple to install but is an additional box. Two other key points with the USB PC's is that you can plug in a quickshifter which you get for a 100 quid as opposed to getting yet another box. It also allows you to wire in a map selector switch. For these reasons I am using a PC, but it is for my race bike. |
