We've used the "123" on the London2CapeTown and all our Peking2Paris builds, as well as our standard road cars - they're excellent.
- Programmable by USB connection
- Two curves can be programmed, with rev limits
- Switchable on-the-fly: ie one curve is set for poor quality fuel on the P2P cars
- Fits both the B18 & carburetted B20 motors
