ok i understand all of that but if one of my friends has allready done that could i take my ecu out of my bike and put it in his and change all of that and then put it in my bike is it still going to rember that i change it. cause i would really not like to cut the harness if all possable

No it won't remember the settings. It is the ECU itself that remembers the settings. I wouldn't worry too much about cutting one wire in the harness. Don't worry, you won't mess up anything.

There is another way to pull the wire out, but it involves removing the harness from the ECU and pulling one of the pins out of the harness. It takes a lot longer to do, but it can be done.

Can somebody give me an idea of how much is one point and if I just put samson pipes on would one click be close to what I need or two or???.
I know that I should be able to just ride it and tell but I am not that knowledgeable[:I]

Help Please guys!! I have the Churchkeys BAK and Vance&Hines 2-1 Pro-pipe. I live at about 1000ft above sealevel. I just did this self ECU adjstment. My stok setting was C01= -3 and CO2=+2. I just bumped it up 2points on each cylinder so it is now -1 and +4. Should this be good or wold any one recommend to bumkp it up more? I went for a ride and honestly I dont know what Im looking for.

You are going to have to pull you left side plugs and look at them to tell for sure. All we can do on here is guess, and that's not really very accurate. You don't want your plugs to be black or ash white. I nice golden tan color is what you are after.

ok guys I have a question, I remember the previous owner of my bike saying that he had someone program the ecu Without the PCIII, which I never heard of anyone doing so I just let it go from one ear and out the other. Now my question is, if he did have this ecu adjustment done and I installed a PCIII would the PCIII overide what he did? I'm confused as hell!! Maybe I should check the wires on the harness to see if they are cut, that way I would Know if he actually did it right? any response would be great thank you!

No it won't overide what he did! Just check your ecu settings and maybe put them to 0-0 and get a custom map or get a wideband to adjust your pcIII to perfection.

'k nother question. PO put a BUB Slash Cut Slip-on on my bike. Ran pretty good, and I was happy with it. I was getting about 35-37 MPG. Then I killed my battery (oops). So, with no battery power, does the ECU remember the settings in it, or do they readjust to factory default? Since the battery incident, my mileage has gone up (saw 50 MPG in a 60-65 mph cruise!) but it still runs good. I pulled the rear, leftside plug to see if I'm lean. The grounding strap was white, and half the porcelin was a nice golden tan, the other half was white. I have never worked on a dual plug head, so I don't know what the 50/50 mix means, or even if dual plugs have anything to do with the strange read. Am I lean?

Well, to answer question 1, no the ECU will not forget what you set it to. As to if you're running lean or not it's hard to tell without seeing an actual pic of the plugs. But from how you describe it, yes you do sound just maybe a tad lean but not much.

Hey, thanks for the info thats realy cool. If you can adjust fuel like that could you adjust time?

Hello all, anyone out there on this site that knows of a way to bump the RPM limit up beyond 5500 on the race ECM? Or to adjust the timing, retard or advance? Dyno Jet has one in the works but it has been in the works for over three years now and still no release date. The motor in my Warior is built to handle 7000RPM built by Patrick Racing. I can't get max HP if I can not go to true redline. The only company I have seen that makes a system to do this is Motec Ign. and that is around $10,000 yes you read that right $10k. If anyone knows of a way to adjust the ECM or of another company please let me know. Thanks.

wow! great work ppl. I love this site.

Very Cool! Thanks DFW_Warrior![8D]

For what its worth, I offer a quick visual guide for spark plug health...

I recently bought my used 2002 Warrior and am awaiting delivery of my PCIII, but I went ahead and performed this fun little project anyway. Thanks to the detailed 'how-to' it worked like a champ on the first attempt.[]

I pulled both codes and adjusted each cylinder a couple times and drove it for a test run each time. Since mine were set really rich, I leaned it up a bit and took it for a test drive. I definitely noticed a marked change in power and in the tone of the exhaust - it seemed less 'loud' and a bit underpowered than before. The second time I made it a bit more rich and drove it around a bit again - I can see where the change is gradual and a dynamometer would come in really handy right now.

I'm going to try a couple more settings and see if I can find my sweet spot. What concerned me and made me want to try this was when I swapped out the plugs that came with the bike a couple weeks back I found them pretty black and looking like it was running too rich.

Any reason why the two cylinders would have such disparate settings? Should the second cylinder be adjusted the same as the first? What are the max ranges for adjustment? Are these too many questions?[)]

The more I look around on this forum, the more I learn from happy Warrior owners! Thanks!

Well, the reason for the different settings is because the cylinders are not the same. They are, but they aren't. They get different airflow into them, they have different airflow around the heads which effect cooling and so forth. So they need to be adjusted differently.

Now as for how far is the max range.... your guess is as good as mine. I really don't have the answer for that one.

Any more feed back from self adjusters out there?
