ok so i have a cb500 twin that i use for a stunt bike and wish to change to injection i can use cbr 600 throttle bodys i think but what would be the best ecu to use to controle it? also it only has a single wire temp sendor for the gauges at the moment. i just need a cheap setup i dont want to run the ignition with it. also i dont have a fuel return to the tank is there a way round this? 02 sensor is no probs i can easily fit this. many thanks josh

A Microsquirt would probably be the *best* choice here in terms of size and tuning options, while the minimum that could do a fuel only setup would be an MS1 V2.2. It depends on whether you want a system that can grow with you or a basic system that meets your needs right now.

With the single wire sensor, I'd add a second one for the ECU. It's easier to add a second sensor than trying to share a single wire sensor between the gauge and the ECU.

It would be better to add a return line, even if you have to plumb it to the bottom of the tank.

You say you use this CB500 as a stunt bike? You mean for various types of wheelies and other motorcycle gymnastics? From what I've seen bikes used for that purpose have short lifespans and end up in pieces on Ebay.
