The installation is a little tight, and one of the connectors is a pig to disassemble, but you just need a little patience.
The instructions are a little poor, so I posted my thoughts and how I did it:
forum link here.
Having the Coober is so much better than without, but it's not the cheapest.
I managed to get a discount just by asking.
The Booster Plug is cheaper, and it doesn't appear to hook into the wiring in as many places as the Coober.
The Coober controls:
- Crankshaft Sensor
- Ignition
- Throttle
- Fuel Injection
I worked on the premise: buy cheap, buy twice.
I have no regrets spending a little more on the Coober.
Oh, and apparently Coober worked with KTM to produce their piggy-back ECU; go figure.
