Hi, I would like to start by saying my knowledge of electronics is limited.
I have a jetski that has a speed limiter. The limiter works off a paddle wheel speed sensor. The water travelling past the paddle wheel sends two 4.9V pulses per revolution to the speedo and engine control unit(ECU). When the ski reaches a certain speed, the electronic throttle valve pulls back limiting rpm and speed.
I tried disconnecting the speed sensor and unfortunately, the ECU sees this as a fault and scary red light comes on on the dash.
Ideally, I would like to put a module between speed sensor and ECU that limits the pulse frequency so the ECU dosen't know how fast the ski is going. As long as the ECU sees a pulse, it won't go into fault mode.
How do I go about this?
Thanks in advance from electronic toddler.
