When you guys are trying out different maps that you have downloaded and you get a map that has the ecu settings in the notes, do you adjust your ecu to match those settings if you are goinguse that map? I mean the ECU bump on co1 and co2 if anyone is curious.

Mate, big NO.


The PCIII oversteers the stock ECU anywayand apart from that: How would you know that bumping up, let's say, +2 on your ECU is aquivalent to what on the PCIII and vice versa?


If you are concerned about that, then I would suggest to tune up the ECU first until you get the required color on the sparks and then adding the PCIII with a map, preferrebly a custom map.

We believe the ECU Bump only affects the idle rpm. Don't bump your ECU to match simply because you install a PC3 and have mods to match some other bike. Its possibly better to add an rpm line in the PC3 for idle. One method is to use your 1,000rpm data line for a 500rpm or a 750rpm data line, sandwiching the 850~950rpm idle spec. This keeps the bike's modified air:fuel the same at cold and warmidle. Others say to start the data lines at 1,000rpm and let the ecu handle air:fuel at warm idle, but some guys get a hesitation off-idle and we don't know yet if the two are related.


IMO leave the ECU at the factory settings.If you ever decide to bump it then record the OEM CO1 and CO2 settings in case you have to go back to them. These factory settings vary by bike so you can't be sure where it was set on leaving the factory unless you record them in your bikes owner's manual for safe keeping.


There's more info in Popular Mods in the Technical forum. Look under ECU.

After bricking my pcIII and doing the bump to get me by until my pcIII comes back from dynojet I did some thinking. The PCIII recieves the pulses from the ecm that are meant to fire the injectors. It then takes that info, figures rpm and looks at throttle position. Now it selects what cell is appropriate and applies the number in that cell +or- to the amount that the ecm is requesting. I believe that the ecm co# has alot to do with a downloaded map. If the co# on the ecm is -1 and 2 on a map tuned for a bike identical to yours but your bike is set at 1 and 4 then the map will be running you way rich because it is adding or subtracting the fuel the the ecm is demanding. Make sense to anyone or do I need to drink more fluids?

Yes, and No. Do a search on this topic. At least two members have had their bikes on the dyno while bumping the ECU and reading the PC3. They both report zero difference from changing the ECU CO1 CO2 settings EXCEPT AT IDLE. While you could be right with your post, its more likely you are simply where we were six months ago when we discovered we might be wrong. Its a work in progress. However, if the dyno doesn't see ECUBump changes past idle, that means something. Here's an example post: http://rswarrior.com/forums/p/118282/955030.aspx#955030


Once your PC3 is installed, get a dyno tune and check a few bump settings tosee if your info differs, we could use all the data on this we can get. Seriously.


Note we don't know if the Warrior is unique in this but probably its not unique.
