Who makes a wide rear sprocket?

But then even if I mount a tire of a different height than the original (for example 225- 45/15) will the control unit become limping?

If you don't sort out the electronics programming (ECM, TCM, dash etc) it's not going to work. There have been attempts to "convert" to an 89t from a 79t but have failed due to the inability to "reprogram" the existing computer(s)/dash. You most likely will end up having to replace all the affected electronics with items from an 89t machine and then do the required programming.... Gonna be pricey if this is the only way. I still feel that there must be a way to reprogram the existing hardware but that BRP has that locked down to their access only and/or it is so convoluted no one else can get it sorted out.

But has anyone tried to understand why the control unit gives the error? perhaps because it reads a different speed than
at the engine revs for which it was programmed?

Yes, that is precisely why it does not work.

When I had the bike and I changed the pinion, I had mounted an electronic device that was used to bring back on the instrumentation the correct speed since the change of the pinion had altered it. Do you think it could be useful in our case?
