I currently have a 748E 2001 model and I have been contemplating fitting a set of 45mm termignoni’s.

Will I need to change the ECU chip or will the standard fit chip still do the job, I’m a bit wary of messing around with the ECU, the last thing I want to do is screw the standard chip/housing and end up with expensive bill to sort it all out and/or a bike that runs like a Russian tractor.

The price of second hand termis seems quite good at the moment but with the addition of a new chip/second ECU and set-up costs it may well be a none runner.

I'm sure many of you have fitted them (mechanically a straight forward job) and changed ECU chips, so any info would be very helpful

Apart from the obvious pipe diameter whats the main difference between 45mm and 50mm pipes from a performance and suitablilty point of view?
