Yes that tune will get you in the ballpark, but every bike is different, and it is always nice to have a custom tune. The 20050_3 tune was also done with the pod filters but it has worked fine for me. I have added some fuel to the L maps to lessen the decel popping.

Probably. They don't make it easy. Getting it back on was surprisingly easier when you can orient the clamps so you can get to them.

Thought I would give a little update since several of you were so helpful in getting me started with Tuneboy and installing K&N's. All of your suggestions saved me a lot of time and trouble so again, thanks.

First, on Tuneboy, I did have a little trouble setting up communication with my ECU. I did have to change to Windows 98 emulation just to get TuneEdit to open. Then, it was a matter of selecting the right serial port to get it talking to my ECU. Even though I had the USB Tuneboy cable, I had to select the Tuneboy serial com and then select box 2 under that. Finally, the Download box would turn yellow indicating a download could be attempted. I then downloaded tune 20500_3 from the website, added that to the tunes in TuneEdit, and finally started the download to my ECU. The first time, the download timed out but when I tried it the second time, it finished downloading successfully. Later, I checked my ECU to confirm that it had downloaded the tune and it showed tune 20050 so I believe I'm OK.

Next came that fun task of removing all the existing air plenums and tubing. Actually, it wasn't as hard as I expected. Then, I installed the 3 RU-2780 K&N's. As Pig9R had suggested, I had also bought small K&N filters for the crankcase breather and the air temp sensor. I used the #62-1340 for the air temp sensor and the #62-1560 for the crankcase breather. If I'm not mistaken, this is backwards from the way Pig9R installed these 2 filters, but this way seemed to work very well for me. I still have to fasten the air temp sensor close to the first K&N RU-2780 and zip tie the MAP sensor somewhere under the tank. Then, I'll play around with modifying the BC a bit.

All in all, this mod has not been too difficult but, then again, I haven't fired up the bike to make sure it runs like it should. I'll plan to post a note on how this improved performance once I have a chance to check it out. I have a few other things I want to do first while I have all the covers off and the tank raised. Thanks again for all your help. --Ken B.

Make sure you turn off the O2 sensor under tune constants and reload the tune.

Hey Pig9r! You've been such a great help and I trust your advice. Your last tip above probably explains why I noticed I still have a lot of decel popping even with the 20050_3 tune. I did not do the 12 minute tune after loading the new tune so I thought I would be OK. Also, I thought I had to install one of those O2 eliminator gadgets from Dynojet to be able to turn off the O2 sensor in tune constants. From what you're saying, it sounds like I can just leave the 02 sensor in place and simply turn it off in the software. Is that correct? Any other tips for me? Thanks again-Ken B.

I just turned off the O2 sensor and reloaded. Now, my engine check light is on. Will it go off by itself or will I need to do something further. Thanks!

Hornblower · 07-29-2007, 05:52 PM

OK on the check light now...I just cranked it up and the check light went out. Unless Pig9r or anybody else has any other important suggestions, I going to go riding now and enjoy my new performance gains. The next project is to modify the BC but I'm just leaving it off for now and hoping I don't run into any downpours. Thanks-Ken B.

Yes you can turn the O2 sensor off with Tunedit now. However you will have popping on decel if you downloaded any of Wayne's maps. The recipe to reducing the popping is here http://www.r3owners.net/showthread.php?t=1804 This has worked well for me. You could go even higher in the RPM range if you liked. Since the O2 sensor is disabled there will be no return of the popping.

Actually Pig9r, I don't mind the decel popping so I'll probably just leave Wayne's tune in there for now. Now, that I've turned off the O2 sensor, I guess it's fair to say I'm running in "open loop". Logically, the closed loop setup from the factory seems more sophisticated but hey, if it performs better this way, I'm not going to worry about it. Now, that the O2 sensor is turned off, am I right that the 12-minute tune is no longer operative? I think I'm at about 1000' above sea level here so if I go to a 5000' elevation, would I need to change my tune? I'd appreciate any comments on these things if you can. Thanks again-Ken B.

With the O2 sensor off the ECU will not make changes to the fuel maps in areas where the a/f ratio is 14.57 to 1. Otherwise in those areas when running closed loop the ECU will trim the fuel map back to the 14.57 A/F ratio which defeats the purpose of adding a custom tune. With the O2 sensor not giving feed back I don't see a reason to reset adaptions however I am not entirely sure on this and I wouldn't rule it out as a possiblity if trouble shooting.

Pig9r · 07-30-2007, 12:30 PM

Also keep in mind the decel "afterfiring" is caused by a lean condition.
