I just got one direct from Dynojet on Ebay for $33!(!!!) Any one got a starting point map they'd like to share with me for my XB9R? Also, I have no experience at all wih these, so any experience shared would be appreciated. Thanks. Sherm | ||

Sherm, I just richened mine up across the board until I can get time to load a map. I've been in close contact with Cruisin as he just got his installed. He has the same map that I have. I trying to find some info out from Montgomery HD since they say they're a Certified Dynojet Tuning place but so far no luck. I am very happy with mine as it is and Cruisin said it is even smoother with the map it just needs tweaked some. I'll let you know how it goes in the near future. I'll email you the map I have. Later, Odie | ||

Bigsherm,I just recieved mine from K&N that I won on ebay for $34.I loaded the 2000 ECU with K&N filter and stock exhaust.It seems to run smoother and throttle response is way better. | ||

Thanks, Pup. ...and, Odie, good to hear from you again, thanks again for the use of your rear pegs last year (never thought a Blackhawk guy could be so cool...) What's the deal, altogether, I mean, how easy is it to load maps on the thing? I have this oooooooooollllllldddddd laptop... What do you do, just determine adding, or subtracting fuel at certain RPM's? I've not had any experience at all with Power Commanders. Thanks, again. Sherm | ||

Which part number PC will work with an XB12 ??? THANKS !!! EE | ||
| Odie |
Sherm, you need a laptop or computer that is near your bike to load a map. Like I said, I have just richened mine up across the board (your instructions will tell you how to do this; no computer needed) until I get the time to load a map. You ultimately need a dyno with A/F sniffer to get max power out of it as you can adjust it in 500 rpm intervals. It is working out very well for me so far and Cruisin is tweaking his map now. I think things will slow down for me next week so maybe I can get a map loaded and go from there. If you need some help just ask. If you got the PCIII for an S3 you will need to lengthen the black wire going to the battery as the layout was different on the S3 vs. the XB. Other than that it is a simple install. I recommend getting the 4-wire O2 sensor also. It is Bosch part # 15716. Fits a 2002 Ford Explorer with a 4.6 engine among tons of other vehicles. Cost me about $49 at Advance Auto. You will need you Service Manual and a little patience to install it as the fan needs to come out and you need a 3/4" O2 sensor socket or a crowsfoot to get the old out and the new in. Let me know if you need help. Later, Odie | ||

Bigsherm,I have an old laptop too that I am using.It is very simple to load maps,hook it up and load. | ||
| Odie |
Eexb, the one I'm running is a K&N (dynojet makes it) part # 83804-211 for a 99-00 S3/S3T. Odie | ||
| Odie |
This ones for you Sherm!!  | ||

Thanks, again, Odie- I'm sure I'll be getting in touch with you soon with more questions. By the way, I'm coming to Rucker in October for the safety course. We gotta ride. See you there! Sherm | ||
| Odie |
Sherm- sounds like a plan!!! Heat index should be down around 100 instead of 115 by then too! Later, Odie | ||

Hi you guys, I am the Dyno Tunner / Manager of Preformance Services for H-D Buell of Vallejo CA. I own an 02 ST3 with Stage 1 mods and a DynoJet PC3 including the optional 02 sensor. My bike with stock heads, bore and stroke and the "Buell Super Trap" makes 99.85 at the rear wheel. I have also tunned an XB9 with a Nallin 1050 kit, Stg 3 heads, Red Shift 585 V2 heads and Ti Force pipe to 103 hp. The key to using a PC on a Buell pre or Post XB is to understand where the "Closed Loop" section of the MAP resides and how it works. Buells use this section to control the "Adaptive Fuel Value" and it's how the Dyno Jet optional 02 sensor functions in closed loop that makes dyno tunning work. The following is my suggestion. 1. Find a Dyno Jet Tuning Center that understands Buells. 2. All 803 PC3's are the same reguardless of P/N. Dyno Jet had two different P/N but only the MAP's were different, they never did change anything on the PC it's self. 3. Install the optional 02 sensor it is a four wire sensor and is powered. Start with a MAP from the CD or online, but chose one followed by an "S" 4. I have had the best results by using "0" in the "Closed Loop" section and setting the 02 sensor to 1, which is 1 unit rich. I then use the "Dyno Jet Tuning Link Software" and tune all other areas outside "Closed Loop" to 13.5 Air/Fuel (Caution) Head temp is an issue and tunning needs to be accomplished between 260 and 285 deg F. Above 300 deg the ECM starts adding fuel values to try and control the engine temp. You will be up on top doing roll-on's at 60% to 100% throttle and trying to remove fuel while the ECM is adding fuel due to engine temp. I takes me between 3 to 4 hours to tune a Buell and we charge $325 for our time. | ||

Buelldyno_guy- thanks much! Finding a Buell friendly place with a dyno around me is the hard part. I'm trying though. | ||
| Alstroker |
How in the world do you figure out where the closed loop section of the ecm is? | ||
| Skully |
The info that is available on Power Commander's web site lists the closed loop section as 0-3500 rpm and 0-20% throttle position. Check out http://www.powercommander.com/man_chp4_pg17.shtml Terry - A recent dyno run at full throttle shows that my bike (XB9, perforated air box, and D&D muffler) goes from lean (15.6:1) at 2200 rpm to rich (12:1) at 3200. What would be the best setting for the closed loop section? Making it any richer makes the bike run poorly in the closed loop section. Thanks, Keith | ||

Does anyone have a map downloaded from the PCIII on there computer that they can email me as a starting point on the XB. I've looked through the knowledge base but didn't have much luck. It would be nice if we could add an area just for maps because I've seen this question come up before. If you use a Palm device you should be able to ride the bike and monitor the air/fuel ratio and adjust it with the PowerCommander software, although I haven't been able to test this yet. If you have the Techno Reaserch software and you log up to 5 min. of riding and then go back and adjust your map. My configuration is the stock ecm, race muffler, K&N, and four wire 02 sensor. There was a posting in the Quick Board a week or two ago and a member listed the Bosch PN# for the 4 wire O2 sensor and I was able to pic it up at a local autoparts store for around $55. I'm still working on getting all the parts togather to put my bike back togather before testing. | ||
| Skully |
Scitz - I can send you mine or you can download any of several from the power commander web site. What is your current set up? Keith | ||
| Indy_bueller |
This is an EXCELLENT thread. I'm going to have to cut and paste this and keep it. VERY goo info. | ||
| Alstroker |
Yea, this is the kind of info I have been looking for for 6 months. I really think these engines have a lot of potential. Stock they run too lean IMHO, so when any exhaust mods are made It just makes it worse. Keep it coming guys. | ||

What Odie and I have BOTH found was that although the TFI does an okay job, the Power Commander does a great job. As I mentioned to Odie, I have a digital readout on my dash that's connected to the O2 sensor. Now that I have the hi-perf. O2, the readout is actually useable. I went for about 130 miles and it was a pretty consistent at cruise .830 (bounced around a little, like .825 and .835). I can see when I smack the throttle open it jumps to above .9xx and it's too rich. I can see what RPM's I'm at when I do it, so I know roughly where I need to tweak. It takes longer to do it, but given a couple of hours I can run...come back to the garage, hook it in and change a few numbers, then get right back out before the engine has a chance to cool. What I'm anxious to see is when I'm all done, how close my map will be to Odie's dyno tuned one. | ||

This may help someone. Only $2995 | ||

Cruisin - As I mentioned to Odie, I have a digital readout on my dash that's connected to the O2 sensor. Now that I have the hi-perf. O2, the readout is actually useable. What are you using? What I'm anxious to see is when I'm all done, how close my map will be to Odie's dyno tuned one. Most likely the maps won't be the same unless you have very similar intake and exhaust set ups. I have found that none of the existing maps that I have been able to download from Dynojet's web site or from others works with my set up (perforated air box, K&N filter, D&D muffler, Race ECM). Blake reminded me that I had some dyno runs that had air/fuel ratios recorded so I developed a map based on that. The bike runs much better now. Is it optimized? Probably not. Keith | ||
| Cruisin |
It was back in the archives quite a bit, Mike and I each picked one up. You can choose the color of the readout, but here's the link  http://www.dynotunenitrous.com/store/Scripts/prodView.asp?idproduct=129 .800 is 14.2:1 ratio .875 is 13.5:1 ratio (MAX POWER) .900 is 13.2:1 ratio Odie and I have identical setups (open airbox, removed snorkle, stock header, and special ops pipe). If my theory is correct and this works correctly, I should be able to tune it for the right a/f ratio...which should create the best power output. In theory... And for $69 I know if the bike is lean or rich, so it's a worthwhile investment. (Message edited by cruisin on August 24, 2005) | ||

You Guys are doing great, keep it up and I think you all understand more than you think. I am willing to share a few MAPs, but please don't hold me or H-D Buell of Vallejo responsible if you don't run then on the dyno and check for any lean cells. These are "Custom MAPs" developed during a run and as a rule are leaner than the (Safe) DynoJet ones you down load. Remember also the intake seal issue 2 years or 5K miles. Bad seals show up at idle and off idle. If bad enough the lean condition will effect the Adaptive Fuel Value or AFV as the H-D Scandalizer calls it. (Side note) there is also a new fuel pump available that helps prevent a lean condition caused by the pump caveating when the fuel level is low or during hard braking followed by a sharp RH turn. Per the Buell Instructors the AFV starts to (Drive Up) correcting for a lean condition before the low fuel light comes on. We found out on our race bike, replaced the pump and all is well, Hope all this helps Terry PS The "Closed Loop" section on XB's is bigger that the older bikes, it runs from 1K to 4K rpm and from 0 (Zero) throttle thru 80% throttle. Also the TP sensor is not linear and is is the weak link in the DynoJet PC3 system. | ||
| Indy_bueller |
Terry, Your statement about the intake seal threw me for a loop. Can you explain that? | ||
| Buelldyno_guy |
Sure, Sporster and Buell intake seals don't seem to last as long as the ones on twin cam's do (Note) they use the same seals. All these bikes have a intake manafolds that float and the seals need to stay flexable as they move. As the engine heats up the cylinders expand and grow away from each other at the top where the heads are. The manafold connects to each head and the seals are warrented as a EPA/ Smogg item for 5 years or 13K miles. At idle use propane gas or some type of spray cleaner looking for a rise or drop in rpm. You need to fix leake before you can tune down low. | ||
| Indy_bueller |
Cool, thanks for the info. I'm having my 5k service done this weekend, I will tell them to make sure they check 'em. | ||
| Cruisin |
Buelldyno_guy On DynoJet's site they recommend not touching "the box" which includes the closed loop section. Not adding any fuel for up to 4k rpms and 80% throttle seems like it wouldn't give you the right performance for the low end grunt. What's your thoughts? BTW - Send over those maps - and a detail of the mods done for them too. I'm going to be posting all of them on my site. CruiSin @ xb12r.com | ||
| Odie |
The way I understood it was that you shouldn't alter "the box" without the 4-wire/heated O2 sensor but you could if you had it installed!?!?!? |
