Got a wiring diagram off the bike?

One wires a 5v feed, one the signal and the other an earth.

Sure someone will be along soon with the link to the checking procedure.

You will need an Ohm meter to check which wire is which as I am not sure of the colours.

Hi, use a multimeter to find out which pair of TPS wires reads between 2K and 5K, with the meter still connected move the throttle, the reading on the meter should NOT change (these will be GROUND and 5v REF, to be confirmed later). If it does try another pair until you find 2 wires that remain the same reading when moving the throttle. Next, you need to find the pair of wires that have the lowest reading (with throttle closed) - with the meter still connected move the throttle, the reading should get higher. One of these wires is the GROUND the other the SIGNAL.

When you have connected the 3 wires to the megasquirt you can easily check you have it right by calibrating the TPS, if it will not calibrate you may have the GROUND and SIGNAL wires crossed.

We have fitted megasquirts to Hayabusa engines before, both the older (1999-2007) and the newer "08" motor.

We normally only use MS2, if you upgrade to MS2 i can let you have a map to get you going.

Hi, i see!
we can do it if you like? install, wire and map at the right price.

I would recomend you upgrade to MS2, you dont need to relace your MS1 on the chip inside.
