ECU Flashing Service

[Maj]

Strange and nasty business aside, I'd like to know a bit more about "flashing" which I presume is a program which re-tunes the existing ECU.
I am not putting any doubts into this obviously successful road to power and I also presume that it is reliable and won't destroy the ECU and associated bits. In short, I need to be educated about this procedure because up till now, I only understood that a better power delivery was usually done with a power-commander, a new set of flow pipes/headers and a jolly good "dyno tune".
Now, it seems that even a PC3 is not needed to get the same results. Just one question, would this automatically void all pre-existing warranty arrangements? If so, I guess it's usually done after the 2 year period (from new).

Powercommander,bazzaz,flash or even yoshbox recalibrate , if it puts your a/f ratios and timing where it needs to be for max power then thats what you will have , engine mods and exhausts etc from that point to gain more power (and again tuned to suit)
Powercommander name was great marketing ...

Warranty would depend on your dealer, many will not cover even a bike wih a Powercommander... flash would be impossible to tell, same as a suzuki or yosh box recalibrate .
Flash lets you adjust your fuel and ign maps, customise the rpm limits
inc,turn off the 6th gear low rpm limit .
also for racing apps some of the flapper valve or pair valve solenoids can be reset to operate nitrous or boost control ,
engine kill for speed shifting is also an option,
as is turning off the ram air compensation when dynoing , so your tune is still correct when back out on the road.
if you want more info about what flashing can do its easier to download the programe, its free ...and look at the various features yourself
