I am UK based and have recently purchased a race car fitted with a UK CBR1000rr4/5 engine. The ECU is from a US (non HISS) model, the 38770-MEL-672. The Honda quoted power is higher for the UK bike at 124kW(170 hp)/11250rpm.
So my question is: What differences are there between the two ECU's? Are there different spark and fuelling maps? My problem is that the rules of the race series restrict me to fuelling only changes i.e. not spark timing, so I need to select the better base spark map for 98 RON fuel, if there is a difference for UK fuel / US emissions etc.
Can anyone help please??
