I recently purchased a VDSTS to reset my TPS. I'm not sure what I'm doing wrong but I can't seem to get a good throttle response when I reset my TPS. I can read the values on the laptop using my new VDSTS program. It starts off at 0 then advances as I increase the throttle but then the bike starts spitting,sputtering and backfiring until it stalls. Is it possible the race ECM that I purchased off ebay for my XB12R is bad? Or am I not resetting the TPS properly? If anyone has experienced this problem,your input would be greatly appreciated. | ||

when you are resetting the TPS are you putting it back at 0 or 5.2-5.6 When resetting the TPS on Digital Tech it has to be zeroed out then set 5.2-5.6, I have mine set at 6 because I found out that 5.6 was still a little low. | ||
| Hd_xb12r |
It's set at zero. How do you set it to 5.2-5.6 with the VDSTS? | ||
| Lucas70374 |
I am not sure, Never used the vdsts, I know with the digital tech it has a readout that tells you what the TPS is set at and it tells you on the computer to set it to 5.2 to 5.6 Might want to read the owners manual to see if it mentions anything about that, or if anyone that has that can let you know how they done that. I had to reset my TPS this morning and it was running horrible then I reset it and ran alot better | ||

The instructions are very vague for the VDSTS. It mentions noting on instructions on how to perform the reset. | ||
| Lucas70374 |
I wish I could help but I have never used a set up like that. | ||

Thank you for all your input Lucas. At least I have a direction to go in now. I'll see if I could find more info on this unit to change the settings. | ||

Turn idle screw counter-clockwise till you are sure the throttle plate is closed. Open and let throttle snap shut on it's own to insure throttle is completely closed. Reset throttle sensor with VDSTS so it indicates zero on the screen. Then turn throttle screw clockwise to about 5.6. It is indicated where the voltage is displayed. You might have to turn it up a little when it warms up. | ||

Ok,I adjusted it as you informed me so I believe the TPS is set properly but I am still spitting,sputtering and stalling. The bike won't stay idling. Sounds like fireworks going off over here. | ||

Have you checked for possible bad intake seal? Have you checked the plugs? If the plugs are fine try spraying some brake cleaner at the seal when the bike is running and see if it almost shuts down or breaks up more. | ||

You need to reset the TPS according to the Service Manual Instructions. Condensed version for my 03 XB9R 1. Connect VDSTS, bike not running 2. Back off idle till TPS is at 0 degrees. Back out idle screw an additional 1-2 turns. 3. Open and snap shut throttle 2-3 times 4. Choose Zero TPS function on the VDSTS (under active tests). Function takes about 15 seconds. 6. Go back to TPS data screen 7. Turn idle screw till idle is between 5.2 and 5.6 degrees. 8. Start Vehicle 9. Run till engine temp shows at least 270 degrees F. 10. Set idle to 1050-1100 RPM DONE | ||

dont forget AFV reset as well | ||

Lucas is talking about the voltage output of the actual throttle position sensor itself. That voltage is supposed to be within a range for full open. That is NOT what you should be concerned about in performing a TPS reset. What you are concerned about in performing the reset, is having the ECM read whatever the TPS output voltage might be when the throttle is fully 100% completely closed (idle screw backed out). You can check the TPS output voltage at WOT with just a voltmeter. If it is not within the specified range, you'll then need to adjust the the sensor itself to get it within the specified range and then you need to perform the "TPS Reset", really "ECM Calibration for TPS voltage". Hope that helps. If you don't have the service manual, please get one!  | ||

Thanks Chainsaw for posting the procedure. | ||

Well I got to reset the TPS like you told me and the bike idles fine,thank you for your help.Now I have another problem though. I took the XB12R for a ride and the bike kept pinging as I was releasing the clutch as though the timing was off. Remember I mentioned I installed a race ECM? Was there something I missed? I thought it was just a plug and play module aside from the TPS reset. I got so frustrated that I installed the stock ECM and reset the TPS once again. The bike is now running great aside from the check engine light that now won't go out,lol. I'm running out of options and patience. Maybe the stock ECM is setting the check engine light on because the exhaust module is disconnected. Which I took off when I installed the jardine exhaust as instructed. Any suggestions? | ||

Maybe the stock ECM is setting the check engine light on because the exhaust module is disconnected Bingo! I think American Sport Bike or Trojan sells a dohickie to cure that problem. No idea on the pinging.  | ||

yes...interactive exhaust emulator is what you need. | ||

First post to the group in a long time... I to just got the "Diagnostic Scan Tool for Windows" from American Sport Bike and wanted to reset my TPS last evening, but with no success. The Bike (2000 X1) was fitted by the previous owner with a full aftermarket exhaust, headers by Kooks and a strange looking pipe "A3 Racing"?, gutted air box and stock ECM. I replaced the ECM with a Buell race ECM and couldn't stand the two week wait to have the TPS serviced by the local dealer, so being the do-it-yourself'er I bucked up or the Scanalyzer kit. I printed the directions for the 2-min TPS reset, but navigating the scan tool from the laptop resembeled nothing close to the community online TPS reset instructions (found in BWB & X1-Files), and ultimately nothing was accomplished. Has anyone else bought this tool and how did you fair with using it. Thanks in advance. Eric SF, CA | ||

Sfmc_x1: I've got the software. It reads the dongle but not the ECM. I'm waiting for the Keyspan USB adapter to get here. Tried it with another USB serial adapter and an add in PCMCIA card on my Gateway laptop with no luck. If you got yours to talk to the ECM you're in way better shape than me so far. | ||

First off... I'm not the most computer savey person in the world. My experience so far is comparable to the hair pulling situation's read in the archive link. Once the Scan kit arrived I was halted by the fact that the db conection wasn't compatible to my laptop (gateway) which has a db15 serial port, not a db9. I went to the CompUSA to buy an adaptor which put me at my present point. I was able to link up but not able to alter or reset any of the functions on the bike, pretty much a stalemate. The most I could accomplish was connecting and disconect, but only from Com#3, nothing else. The program fired a lot errors and malfunction mumbo jumbo at me, everything to ecm failures sensors failurs and dongle not responding. The tech at the CompUSA did mention that I was not going to be able to communicate with the bike via the serial port connection, explaining that it dosent work that way, a second friend mentioned the same thing... shophisticated info cant be transfered via the db serial port. So, I did pick up the Keyspan USB serial adapter last afternoon at thye local Fry's Electronics as recomended by the company that made the kit. I'm going to see what happens when the sun comes up. I'm set to go through with doing this reset myself, I'll keep the forum updated. | ||

BTW: 5liter. Thank you for posting up that Archive link. It was good to read that getting the USB adapter is a neccessity. I hope I can pull this TPS reset off, there's still alot of riding left this season, I don't want to waste it wrenching. | ||

Sfmc_x1: Keep us posted. My Keyspan adapter is'nt here yet. As you read I'm having fits with a non Keyspan adapter and a PCMCIA serial port card. | ||

"..laptop (gateway) which has a db15 serial port..." Are you sure that is a serial port? The DB-15S (socket or female) connectors found on most laptops are the VGA/SVGA connector for an external monitor. If it has markings on the ports, the square with a bar on each side is for a monitor, the serial port marking looks like a snake swallowing two cubes. Jack | ||

Hey read the disclaimer... sfmc-x1<--- not the most comp savey guy in the world, the one and only plug on the back of my laptop is a 15 hole/female connector, and when it comes to computer lingo, I don't know my a$$ from a hole in the ground. Anyway, so I hooked up the Keyspan connector, nothing is different, still not able to run test's. It would appear that the program will connect and disconnect at will with no input from me. I'm still not able to access the throttle sensor option, the absolute most i can do is clear DTC's. Its pretty frustrating, when the program seems like its working and I ask it to run a test, it shoots me a list of errors and short circut mumbo jumbo followed by more disconect's. I tried calling techno research but no one picked up. I'm lost on this one folks. | ||

Sfmc_x1: Did you go to VIEW>SCM Information and hit READ?? You need to do that first thing. | ||

hd-xb: your post is a bit tangled. my race ECM pinged visciously the first time on the road, problem cured itself (went away) after shutdown and restart. your post makes mention of two ecm's the RACE ecm does not need the interactive muffler servo. the stock ecm wants to know that the servo is there, or it will trip the check engine indicator. it sounds as though you were initially restting your tps value with the throttle partially open: this will not work. the throttle must be completely CLOSED at the moment the TPS value is reset ( thus the term ZERO). after you have reset the tps with the throttle plate ALL THE WAY CLOSED, you then adjust the idle speed to the approximate value given to get the bike to start, then you adjust it to idle at 1100 rpm or so. the technoresearch software can be a tad finicky, like any windows based toys, but the price is right, and at least you are free to screw things up your self, as opposed to paying some one that should know better to practice screwing up your bike. if you have any problems call Giamberto at technoresearch, once you get his Italian accent figured out, he is VERY knowledgeable, and also real helpful. good luck. dean. | ||

Okay, I got the the scan tool kit to work and believe I pulled off reseting the TPS. I called Al at American Sport Bike, he mentioned a possible fault in the software and recomended uninstalling the program and downloading an update from Technoresearch, if problems continue... call the tech assist at Techno, I did and I got to speak to Giamberto. First: He mentioned that since I'm running the Keyspan adapter that I must have the driver for that application enabled, I confirmed that it was. Second: He questioned if the Dongle (grey adapter that links the two cables) was in the right direction, aparently this matters. I mentioned to him that I did disassemle the cables when I tried to use a db9 to db15 gender bender before obtaining the Kespan adapter. Once the Dongle is reading the ECM and allowing the the transfer of info, you get to see the computer read the bike in real time via the guage and graph icons. He walked me through the program and stated that the user must reconect when going through each function/icon of the program, as it dosen't do it automatically. That being the end of the conversation, I optioned the TPS feature from the active settings, the feature showed me a countdown and read "PASS". Per the guage/graph feature in this program the TPS now reads 0.0 I then adjusted my idle to just below 1100rpm, and that was it. I guess what the important question is, did I do this correctly? | ||

Sfmc_x1: What version of the software do you have? Mine is 2.77B I'm connecting OK now, but the ECM stops responding after 30 seconds or so. | ||

Finally got the software working! Installed Race ECM and zeroed the TPS per instructions. Bike runs great now! |
