And I realized that I only answered part of the question. The purpose of a PC is to map the FI on a bike with greater resolution than the stock controller. The end result is better throttle control through the rpm range (less/no surging etc.) under a wider variation in environmental conditions (temp, humidity, altitude, etc.). Custom maps also allow precise air/fuel control with different types of exhaust and air filter systems which tend to make a bike run leaner than stock.

I think some of you guys are having winter widthdrawl problems or something. Lighten up.

You the man. Just how I like, to the point and all bases covered.

Thanks Bro,

Better resolution, really? I would think that with such piggybacks, as opposed to stand alone, you're limited to the dimensions of the stock maps.

I'd be interested to hear what someone who really knows a lot about the PC would say about this. I really don't think the PC is capable of redefining the addresses and dimensions of the maps, just able to edit the values within and calculate checksum. In automotive OEM fuel injection systems, it's more than difficult (and probably can't be done without manufacurer Damos (definition) files) to make the ECU access areas that it usually doesn't (and who knows if there will be room within the file to augment).

By "greater resolution" do you mean a more customized tune done cell-by-cell or are you actually referring to increasing the dimensions, and so total number of cells, in the maps?

I think maybe is was this post that got you off on the wrong side bud. Starting off calling people dickheads and spermbreath. Then you wonder why people get an attitude. For someone in their 40's you act like a teenager calling names...

The former, of course. Plus, as I understand it (not an expert at all), some older ECU's can't themselves be re-mapped while some of the newer ones can (?).

Get the facts straight, I asked a question, they got shity, I responded with a few choice words.

The power commander is a fooler box. It misrepresents data incoming into the ecu to adjust the fuel and sometimes also the ignition curve. Its a piece of shit in my opinion but its pretty much a standard option on most sportbikes. I can hardly see kids buying good tires often enough to try to sell them a stand alone system.

Uh and your original post sucked. It made no sense at all.

Good info. and point well taken.
I guess what I should be saying here is, I realize that my original post was not the easiest to comprehend. Next time I will be more direct and to the point.

A little about me, I am don't play dead when I'm being hammered.

I only know of one company, in Australia, that will actually reprogram a stock ECU just like a good chiptuner would do with a car. Do you know of anyone that does this stateside?

I'm with you about "foolers," "interceptors," and sensor mods-- not the right way to do things.
