I am wondering what the difference is between a 2002 88 cu in and a 2005 88 cu in. engine in? I have a tuner map that was designed for a 2002, and when I asked Dynojet about it, they said it would cause my engine to run leaner than a map they recommended. The 2002 and mine have almost exactly the same mods, Andrews 26 cams, screaming eagle air cleaner. It has jackpot mufflers and mine has stock. I sent it to FuelMoto but haven't gotten an answer, it is their custom map. I did download it, but am going to change it back. I don't want to risk, damaging my engine.

One issue could be part numbers show different injectors. So one gives different amounts of fuel then the other.

 

Differences; besides the injectors already mentioned, the 02 still had the forged crank, the 05 has stiffer valve springs so you can run a higher lift cam without having your valves float. As far as Power Commander fuel injection maps, those are just numbers on a graph. You can have two motors of the same year, with the same mods, tested back to back on the same dyno under similar conditions and come up with different results. Unless you bring your bike into a dyno and have it tested at a minimum, there is no way to guarantee that it is running at its best.

Go with whatever map pulls hardest and runs smoothest, until you get it on a dyno.

One other thing; if you can, hook up the Power Commander to your computer and verify that the throttle position sensor and the Power Commander are in sync. I am talking about % throttle that shows up on the P/C app. It should be at 0% when throttle is at idle, and obviously 100% when wide open. Very easy to sychronize, and there is a tutorial on the dynojet website that walks you through it. I was trying different maps on mine, then noticed I was at 10% when throttle was at an idle. Sychronized the P/C with ECU, and it all came together.

2002 was the last year for the double Timken bearing bottom end. Should be no difference in mapping requirements.

 

I think the 05 heads are a bit different than previous years.

Is there anyway to do this without a laptop. I don't have a laptop.

If you can get your bike close enough to your PC you can run a cable out to it. Don't exceed 15' tho.

That is the link for the tutorial that explains how to check and set the throttle position values. To start the video, there is a tool bar on the bottom of the screen in the center. Only reason I mention this is it took me a few minutes to find that toolbar.

As far as synchronizing the throttle position without a laptop, as nvsteve said, you can use your home computer. He says do not go over 15' for the USB cable, I say that must be the new thing for me to learn today. I am not very computer friendly, if I cannot fix it by turning it off, and re-starting it, then into the shop it goes.
Anyways, what are you using to download maps to the Power Commander? That should work just fine if it supports the application to send a map from computer to Power Commander.

Yeah that! I was able to run a cable out the window. A little difficult setting the throttle position tho.
