    Not all ECU flashes have the mode set to A when turned on. See if it’ll rev out to the limiter in 4th gear. On a closed road though.

    The fan will kick in at 95℃ instead of 105℃…

      This is probably the easiest way to find out if it’s been flashed.

      Davies well then, if the limiter/governor didn’t cut in, yours likely had the ECU re-flashed.

      Depends on where you live. In the US it is limited more than Euro zone, even in the EU there are differences. Take it you didn’t buy new. Most re-flashes done have A mode on switch on as default – does depend on the model year, apparently and assuming you speaking about the Tracer.

    Take the tank off and look at the ECU, if it opens its greatcoat then the answer is yes.

    Thanks for the advice guys, conclusion is that i don’t think it’s been flashed. So think I’ll be getting it done this winter.
