What if a performance chip is used, will the GS-911 give a false reading?
Chipped bikes are always difficult to predict.. however, if it is a quality chip, then all should work well..
I have the BB Power chip in my 1150GS... and the GS-911 works great.. completely like it should !
Piggy-back devices, such as Techlusion or PowerCommander however, change the Injection (and/or timing) signal after the ECU, i.e. without the ECU knowing about it... thus, if you have a real-time value reading of Injection time of 2.50ms, but you are running a PowerCommander that adds nother 10% at that rpm/TPS operating point, then your real-time value that you will read from the ECU will still show 2.50ms, while the actual injection pulse will be 2.75ms (because of the addition of the 10% (0.25ms) of the PowerCommander).
