One more time ...
The pessimism surrounding this thing astounds even me, self proclaimed "KING-OF-DOOM-AND-GLOOM" !
I guess you haven't been listening, it doesn't do anything TOO the timing. It simply goes inline with the gear position sensor, reads what gear it's in and displays it, then sends a false signal to the ECM tricking it into thinking it is in a higher gear thus advancing the timing to what it would be if allowed to produce full power. It also tells the ECM when it's in neutral so that the idle is smooth, something just putting a resistor inline will not accomplish. Simple yet very productive for the investment in time and money. For those new to this, Triumph programs 1st, 2nd and 3rd gear with retarded timing so that there is reduced available power in order to make the bike safer and more docile. Having the 2300cc engine's full potential available in those lower gears would put less experieced riders at risk of losing control. i.e. pulling wheelies when you don't expect it !?!
This little piece of equipment puts the rider back in control of killing themselves before they reach 4th gear.
It manipulates the computer input signals allowing for three things...
1) the display of what gear you're in
2) full timing advance in every gear (based on your prefered setting)
3) elimination of the top end speed limiter
That's it... And it's VERY suprising to find out how that extra juice feels.
The GiPro has my admiration because it does everything so **** quick that there is no processing delay like you might find in other equipment designed to do the same thing. It also doesn't just send pre-programmed values in place of sensor inputs, it reads, learns and duplicates sensor values already present on the bike (all sensors have slightly different ohm/voltage values), then sends them to the ECM based on what you want it to do.
