How many sensors do you need for this system ?

Throttle position sensor: fits to the throttle body and tells the ecu how much throttle you have open.
Engine temp: this is a temp sensor fitted in one of the engine sump plugs.
Air temp: this is the one in the airbox.
Lambda: this is the sensor in the exhaust which helps keep the mixture at "lambda" which is the optimum air/fuel ratio.

There is also a solenoid on the throttle body which opens up allowing air to bypass the throttle butterfly which increases tick over on warm up when its a cold start. Acting like a choke/fast idle.

And the injector its self.

Hi Nick ..... I think Ural are spying on you .... They've just announced the 2014 models will feature EFI instead of carburation ...... AND they're switching over to disc brakes all round! ...... ..... I hope the rest of your work goes smoothly ...... John

Thanks Nick. Doing away with the choke would be great. My main beefs are the crappy clutch and getting her to idel in cold weather. Interested to see how it pans out

Pic of the engine temp sensor (bmw r1200gs oil temp sensor) in the rear sump plug. Why are there two sump plugs on these bikes???
