Wiring Question

Anywhere on the R3 Std I can pick up a 5VDC supply?

I know a items like the temperature sensor are 5V but I think they are parts of a loop off the ECU. I need a clean 5VD for a MAP sensor to hook into my PCV.

I have the MAP sensor but it requires a 5vdc supply and there doesn't seem to be one on the PCV but it accepts a 0-5VDC input for a MAP sensor.

Thanks in advance, even if its to tell me I'm stuffed and need a different sensor.

Voltage regulator might be required

Just tap into the OEM MAP 5 v supply.That is what others do no problem

Hi Pedro.

Please clarify, there's no MAP 5vdc supply on the ECU (that I know of) as there's no MAP sensor on stock bikes, just Air Temp, this is loop powered so I cannot tap of this.

The PCV has a MAP input but its 0-5vdc, but not loop powered so I need to supply a source voltage to power the sensor seperate from the loop.

If I'm mistaken and there is one, I'm all ears.

All stock bikes have a 1 bar map sensor. That 5 volt pick up on the pcv is to receive say a signal from a 2 or 3 bar map sensor for boost fueling. It probably could also be used for NOS fueling.
