I have a '06 Ulysses that I got privately, which had a Drummer pipe and race ECM. It also came with the VDSTS-Standard software (v2.79H, which I just upgraded to the latest v2.81-D) and Keyspan cable/software. I just obtained a stock Uly pipe, and installed it along with the stock ECM, filter and servo cable. Button it all up, start bike, runs like crap, which is what I expected. Install the VDSTS and keyspan software on the laptop, connect the cable to the bike outlet, somehow get things to communicate. Now what? Start with a TPS reset? Thinking that was the case, so hit the TPS reset button, now it runs even worse and won't idle. Also, the damn software program is connecting and reconnecting. Previous owner says he successfully used it when he installed the Drummer. I downloaded the documentation from the technoresearch.com (maker of VDSTS) which includes instructions on doing a TPS reset on a Buell. But the instructions aren't very good, certainly for a newbie like me who has never done this before. And the "user guide" was useless. It just says what all the buttons are for in the software and what the software can do - doesn't tell you how to setup your bike USING the software. I know lots of you out there have. Can any of you lend a paragraph or three and help a poor noob out? The bike isn't rideable like this. Questions: 1. Once I have the connection made and the software is communicating to the ECU/ECM, what do I do then? Start with TPS reset? Bike running or just turned on? 2. For TPS reset - What do I do with the idle adjustment - back it off completely or just where I think it doesn't interfere with the throttle position? Then do a TPS reset (bike still turned off)? Then adjust the idle screw to where I think it should be (try starting bike and get it around the 1050 rpm area), turn off bike and hit TPS reset again? 3. After I think I have done the TPS reset, start the bike and it runs OK (this is a big assumption at this point), do I do anything else with the software (i.e., do I have to reset anything besides TPS)? I have also posted this to Knowledge Vault, but have gotten no responses yet. TIA, Scott aka "Motogeek" moto.geek@yahoo.com 06 XB12X Ulysses | ||

Resetting the TPS also takes closing the throttle plate completely. Al did a terrific write up on it. http://www.badweatherbikers.com/cgibin/discus/show.cgi?tpc=3842&post=528843#POST 528843 DAve | ||

Thanks, Dave I saw that, but it still doesn't help much. You posted excellent questions to him in that thread that it appears he never answered (he continues by talking about connectivity issues, PDA versions, blah, blah, but doesn't answer your questions about the throttle screw or throttle stop screw: "Posted on Friday, October 21, 2005 - 03:40 pm: -------------------------------------------------------------------------------- Thanks for the documented procedure Al. I just did my XB12X w/out the maintenance manual using the technoresearch software. One area that caused confusion for me was the remote idle adjustment thumb wheel location on the XB. Your optional procedure of zeroing the TPS at 1/3 throttle illustrated the theory nicely. A couple suggestions: - Keep terminology the same throughout. Is the "throttle stop screw" the same as the "throttle screw" and the unspecified item to adjust the idle? (I hope so or my ride to work this evening may be interesting! ) I took the air box and all off looking for separate items because I recall seeing a throttle stop screw on earlier FI. - Could you clarify the throttle position reading of 5.1vdc? That's just an initial setting till idle is adjusted with engine at 320F? Thanks Dave" ---------------------------- That's my biggest question right now, concerning this part of the directions: "The first step of performing a TPS reset is to back the throttle stop screw off until it no longer is touching the stop on the butterfly shaft. The easiest way to check if the throttle stop is no longer engaged is to turn the throttle grip to zero and force it there gently. If when you start to open it, you can feel it gently sticking, this means that the butterfly is wedging in the throttle body and you have achieved absolute closure." All I know of is the idle adjustment screw. Where is the "throttle stop screw"??? So, did he ever answer those via PM or direct email? Can you share them with me? Thanks! - Scott (Message edited by Motogeek on September 10, 2006) (Message edited by Motogeek on September 10, 2006) | ||

You got it....one item called a few different things. The idle thumb screw (engine side of the air scoop) is backed out till the butterfly closes completely. You'll feel resistance to opening when it's actually fully closed in the throttle body after backing it out. The 5.1vdc is an initial setting to get the engine idling. You adjust the idle thumb screw for 1050 RPM (If I recall) at the specified temp. DAve | ||

TPS reset is with the bike off -- I didn't clarify | ||
| Mramsey |
(Bike off) means, engine not running, ignition switch on, and kill switch in run. Of course the engine couldn't be running with the throttle plate closed completely. | ||
| Motogeek |
OK, problem. I've adjusted the idle thumb screw all the way out and all the way in. It appears to "stick" the same regardless of where I have it. Now I have no idea where it should be at the proper idle speed. Ideas? Thanks, - Scott | ||
| Dave |
... what Mramsey said.  Ignition on DAve | ||
| Dave |
With the VDSTS connected and function, zero the TPS then adjust the idle screw till you get a 5.1vdc. That gives you a running bike and not the final idle adjustment. DAve | ||

Hey Scott you can always remove air box and look at throttle plate to make sure it is fully closed. Then after reset just turn screw clockwise until engine will idle at proper rpm. | ||

The VDSTS program remains an enigma, to me, in that I CAN get it to work. But never the same way two times in a row, or so it seems. I've had the best results with the engine at operating temperature. Once at op/temp, turn the idle stop screw out until the lowest voltage is observed. Then open the throttle grip WOT and let is snap back to closed position. (repeat this twice) The throttle plate should be 100% closed at this time. Go to the active test and do TPS reset, then AFV. Then I go back to diag mode (as discussed else where) set the TPS to 5%, start the engine. Let it come back up to Op/temp and set idle to 1150rpm. The above works for me, assuming the VDSTS can communicate with the ECM. | ||

Hey, folks, thanks for all your input. I just got it to WORK! I think the issue was my Keyspan converter. I brought out our home computer which has a DB9 RS-232 port (unlike the laptop, which only has USBs). Anyway, had to install the software, configure the COM port to COM4, connect to bike (NO Keyspan thingie, just the other 2 cables (regular and null modem), tell VDSTS I'm using COM4, connect to ECU, get into diagnostics, get it to see the cable/computer combo, get it talking to the bike, and then get started with the TPS (whew!). Set the TPS at about 1/3 throttle (after I was as sure as I could about the throttle screw (aka idle adjuster thumb screw) - it passed. Go through the other steps, start the bike, and it won't idle, but runs great above. Take it for a ride to confirm and to get bike up to temperature before I set the idle. Runs super strong, no hiccups, pops, backfires, check engine light. I'm happy. Take home, connect back up, set TPS to 5.1 / idle to 1050, disconnect, take for second test ride. Runs PERFECT (better than before, in fact). Realize there IS a God (hey, it's Sunday), ride home, put everything away. Thanks to EVERYONE who responded on this! Have a great day! - Scott (Message edited by Motogeek on September 10, 2006) | ||

This brings up a point which interest me: is there a problem using a USB-to-DB9 serial adapter (like Keyspan)? I was planning on using a PC laptop my son gave me to run VDSTS, but it only has USB. I do have a desktop PC w/DB9 serial, but dragging out out there is kind of a pain. So do the USB-to-serial converters work? No PC/XP lingo, please, I'm a Mac guy! | ||
| Davo |
No, in fact the Keyspan adapter is recommended and sold by American Sport Bike. I have one and it works on my non-mac PC. | ||
| Dave |
Good deal - the next time will be a snap. I use an old Dell laptop without the USB. DAve |
