Somebody explain Power Commander .map vs .djm files to me

I have a '99 and I have run a K&N and an OEM muffler for some time. I have a PCIII USB with the latest firmware and the 'optimized stock' map running.

I just upgraded to a CF Micron slip on and I wanted to try the "Micron slip on, K&N air filter, Modified ignition curve. Only for use with 93 octane or higher fuel." map, but it's only available as a .map file for the PCII. So I read that you can just rename them to .djm so the PCIII software and read them. That does indeed allow me to read them and even using the "import .map file" option in the software reads the original .map file, but in either case, when I try to send it to the PC, it fails with an error about unexpected config error.

Wait, there's more!

I decided to try the "1998-1999 Honda VFR 800, Erion slip-on exhaust, Stock or aftermarket air filter" map and then modify the values to match the one above. The problem is the maps are identical, so I guess my question is if there is something I'm not seeing ?

My whole reason for looking for a Micron slip on map was to try and lessen the pops in the pipe, some of which are quite loud on deceleration.

Any help is appreciated!

 

Not to be a jerk, but I would forget about that whole mess and cough up the $250 for a dynoed custom map. Popping can be a sign of running too lean and even a downloadable map that looks to be fairly precise can cause this to happen, amongst other problems, like running rich. No generic map, despite it looking good and matching your specific mods, is actually specific to your machine. A small investment will maximize your mapping and performance, and unlike tires for example, will last for the duration of your ownership.

 

I get that, and I'm probably going to do that with my big $ bikes like the Hayabusa and the Blackbird, but the VFR800 is just a pet project so i don't want to pay for a full dino just yet. Plus I want to know for my own knowledge, I have Power Commanders on everything except the GT250R and I'm even looking to adapt an SV650 PowerCommander to that to see if I can do it.

 

pc2 software is not going to be compatable with pc3s. the pc2 goes in between the stock harness and ecu. the pc3 goes between the stock harness and fuel injectors. they operate in completely different ways. if you had a pc2 you could adjust the ignition timing as thats built into the unit. but pc3s require an ignition module, which as far as i know is not avaliable for the vfr's. hope that helps
