Map Reloading
Due to some suggestions a couple of years ago from a friend I got in the habit of reloading my maps every time I changed the oil or more frequently. He didnt give a definition for his suggestion other than he felt it (woke the bike up). Maybe this is just psycolgical, but it does feel that the bike is more responsive. I wouldnt go to the extreme that it makes 10 more hp or nothing like that, but it does seem to clean things up. Anyway I was just wondering if others do this and see the same results and does someone have a good explanation as to why you would need to do this or not??

This is not needed. The proper map is either there, or not.

Brock has stated this many times .. The map does get corrupted after some time and NEEDS to be reloaded from time to time ..

I'm going to start reloading mine every time I lube the chain.  Sorry Lee, but that doesn't match my experience...what would cause the map to become corrupt?

Interesting. I'd definitely like to learn more about this issue.
I had 15k miles with the same map on my PC3R (ZX-12) without issue.

I could be wrong, but I think the fuel injection system/ecu starts correcting for atmospheric pressures and such using sensors on the bike. I heard to do the same thing with my programmer for my diesel truck, to reload the program every now and then because the truck automatically starts to adjust it for weather conditions.

me too.
It would seem to be one thing, like a PC for example that will read a file of 1's and O's, and when re-writing that flubs it up once in a while....
I haven't heard that the map gets written to by it's ECU, so unless you'er doing that with your PC, what would cause a corruption?
and if it does get corrupted somehow, then I'd think you could do a map compare, with dynojet setups anyway, and see the changes.
and there is no auto-correction to the FI maps on PC III/Bazzaz setups
Brock. How'd you come to this conclusion?

Wow, that's new news to me.... I've been running my 14 for 2 1/2 years, 5-6 oil changes and still have the original track map loaded. I will revisit and see if/how the bike changes...

Superman and others, why not load the map from the Power Commander back to the laptop and save/rename it so it can be compared with the original map in mapsource to see if any cells are changed. Then we would have an answer.

I have had to reload my map several times. One time, my bike acted up so much I thought my clutch was slipping. Now realize I say this and I am very mechanically inclined and was a mechanic in the air force on C-130's. Every indication I had was the clutch was slipping when I got on the gas hard......
I changed the clutch out (with only 7k-ish miles) and the bike acted the EXACT same as before the clutch install. On a whim, I re-installed the map and it corrected the problem. The "corrupted" map had "developed" a flat spot from 7k-9k that let the motor continue to rev, but did not make power that was consistent with power before and after that point on the rpm's. Previously, the map produced linear power throughout the rpm's. It truely felt like clutch slippage. I even had another mechanic ride it and his assessment was the same as mine.
The next time the bike acted up, I downloaded the map to my laptop and renamed it. I then compared the "corrupted" map and the original map file. I could not find any differences in the two maps, yet the "corrupted" map clearly ran different in the bike.
And for all the "is your PC3 grounded to the battery" comments that always follow posts like this, yes it is properly installed, grounded, and shielded from any magnetic interference that could come from the bike.

It's electronic. Power spikes, emf, static, degradation of the memory chips. I work on handheld computers and barcode scanners. First thing I always do on a handheld is reload the software. Fixes many problems right off the batt.

I've looked at a few maps sometime back, and in addition to the cell information, I believe there is something like a 'header' to the map file as well. Wonder if that could be corrupted, instead, and cause an issue. It does not make sense to have the cell info be ok, and the issues you talk of, unless something else with the map is off.
and could this map corruption be isolated only to say PC's, or ?
I know on the Bazzaz, you can not 'auto map' below 3K. In listening to the Bazzaz folks while my bike was on their dyno, that seemed to come about because they were getting sometype of interferrance from the CAM below 3K which caused readability and reliability issues, and ended up having to put a filter in their Bazzaz gadget, and then their unit only being able to map above 3K. Hope I got that correct from them.
