SR3 Huabusa ECU

[silverthorn2151]

We need to replace the ECU on our 1300 Busa SR3.

Any pointers on where the best place to get one from is?

We assumme it's just unplug and plug in the new one......or is that terribly optomistic of us?

On the original BUSA there are two different ECU's depending on the year because the crank trigger wheels changed. The latest engine is probably different again.

I have a spare off my Westfield from when it was changed to MBE.

I can check the number if of use. Not sure what it is worth.

Ours needs one from a post 93 Busa, which is when they changed I believe.

Could be interesting. PM me with a figure and I'll talk to my chums. We have a couple of other feelers out.

We are still playing with our misfiring SR3.

We took the existing ECU off over the weekend to seposition it out of the engine bay as it was getting very very hot.

We found on doing so that the casing was damaged and cracked at one end. It didn't take much pressure to open that crack to 1mm or so.

Not knowing too much about the internal gubbins of these things could that obvious damage combined with heat and vibration give us a difficult to trace misfire?

It sounds quite possible especially if it's got any damp in it.
