So I recently received my VDSTS and ST Windscreen from Al (fast shipping and no hassles nother big  to American Sportbike). I hook her up and followed the procedure I have seen listed on here. The only issue I ran into was when I opened and snapped closed the throttle I received a "motor problem" error on the VDSTS but nothing came up in the error code box. So I went ahead and finished...started her up and she ran like crap. So I did the hole shebang over but this time I killed the ignition before opening and closing the throttle. Finished up and she ran perfect. While I was at it I decided to check the timing due to my sporadic pinging issue. Just when I buttoned everything back up the thunderstorms started so I could not do a shake down run until today. Throttle response is much improved, shakes less and could not get her to ping. So all is well. | ||

You checked your timing but what did you adjust, anything? I haven't had a pinging problem but I am curious. | ||
| Hooliken |
I retarded the timing the 1mm like has been suggested. It was slightly advanced. | ||
| Bertotti |
Thanks that is great. I wonder just how often this is part of the problem. | ||

Hooliken, What was your procedure for checking the timing? The VDSTS doesn't do that does it? | ||
| Hooliken |
No the Diagnostic software does not aid in checking the timing. I spent about 5 minutes explaining to my wife how to check the static timing and had her read the procedure in the SM and a couple of the threads on here. With what I was able to garner my timing was quite a bit advanced. Since retarding it I have been able to put about 400 miles on it and it has not only gotten rid of the pinging but also has improved overall rideability(sp). Throttle response is crisp and not nearly as much shaking when riding below 3k RPM. Glad I took the time to do it. I will definitely pull the plugs next time I check the timing though. I am a big boy and it still took quite a bit of grunt to turn her over on the stand, in 5th gear. | ||

Hooliken, Great news regarding your adjustment. Do you know where the TDC mark is or did you just retard it from the factory setting? It doesn't really matter other than I am curious. I had an 06 that needed to be adjusted as well. If you are down this way give me a shout. | ||
| Hooliken |
Davo, Without having a digital technician or timing light I just did the wait for the fuel pump to cycle at the front cylinder TDC. My timing mark was showing that I was way advanced. I marked my factory timing per your instructions then retarded roughly 1mm. So far so good. I will add that I trouble finding 10-32 bolts to fit the holes to attach outside cover. Just so everyone knows you can also use M5 bolts in this application. I had some stainless sockethead cap screws (allen head) that worked perfectly. I need to go out and do some "real" riding since most of the riding I have done since adjustment has been highway back and forth to a class I am taking about 90 miles from the house. | ||

Very cool. It is as good time of year to tune due to the extreme heat here in VA. If it ever gets any hotter than this week, then I doubt the bike will leave the garage. I am glad the procedure helped you out. When I saw the 1mm reference I assumed you saw the post. It was the cure for my ills as well. After my tune the engine never pinged again. I had to go 2.5mm and my mark was just leaving the window! Many of the bikes I mess with I use "1/2 way out of the window" to give about 3 degrees of insurance. I figure you can always dial in some more heat. Another way to look at it is, it is better for us to tune late than to ride it after the factory let it go early. | ||

Just an update. Just got home from about 200 miles. I waited for her to get nice and hot with the fan running and lugged it down to about 1500RPM in 2nd and 3rd gear....so far NO PING. Your write up was right on the money Davo. I should be able to get one or two good rides in this week and will probably check the timing again to see if it has walked any.

Excellent! | ||
| Bertotti |
Hooliken what made you go for the vdsts software instead of the ecmspy software? I am looking at both and the free software sounds real tempting. Thanks | ||
| Hooliken |
I guess I am behind the times Bertotti....I know absolutely nothing about the ECMSPY you are referring to. But now I am curious. Got a link to it so I can check it out. I already have the cables so I guess I can now use whatever I want. Took a little while to figure the vdsts out but was not that big of a deal. | ||
| Bertotti |
Well that answers my question. Here is where I heard of it on advriders http://www.advrider.com/forums/showthread.php?t=25 3312 Thanks (Message edited by Bertotti on August 13, 2007) | ||

http://www.badweatherbikers.com/cgibin/discus/show .cgi?tpc=142838&post=951466#POST951466 Im the guy who posted this at Advriders. The software works and a new version is about to be released. I just didn't want to step on anyone's toes that sells VDSTS and supports this site. So I didn't say much here. DaveyMac | ||
| Bertotti |
I haven't any intentions of stepping on any toes either so if I have I apologize. I was just curious. | ||
| Hooliken |
Seems that this software does quite a bit more than the VDSTS. Might be worth having them both!! My personal belief is that since this is something that "HAS" to be done for maintenance so the VDSTS should either come with the bike or we should get a discount on it. Especially with the known treatment most Buell owners get at some of the HD dealers. | ||

Daveymac, Can it check timing?? | ||
| Davo |
Electroglider 1997, The only way to incorporate a timing feature is to design the software to read CPS voltage. On the 06 and 07 models simply substitute the fuel pump cycling on in the place of CPS voltage going to 5 volts. On the 08 models there should be no external/mechanical timing adjustment. You can use VDSTS to read dynamic timing values and then dial it into a variable light but the factory has never made the static to dynamic offset numbers available. It has also been brought to my attention that the VDSTS numbers for spark advance may not be completely reliable ie. numbers in the high 50's and low 60's.

Daveymac, Can it check timing? Yes Running Diagnostics Before modifying your ECM, I strongly recommend running all diagnostics and checking that everything is working correctly! Checking the Static Timing Before spending time on your fuel map, it is wise to check the static timing on the engine. This is done by slowly rotating the engine, whilst watching the Cam Position Sensor on the Diagnostics page. Raise the back wheel off the floor! Remove Timing inspection plug Put bike into 5th gear to ease fine turning of the engine Raise side stand Select Diagnostics page in ECM Spy and connect to the ECM. The CPS value should be 0 or 5, depending on which cylinder is due to fire next. If it is on 0, go to next step, if on 5, rotate backwards until the CPS changes to 0, then follow the next step. Rotate the rear wheel in a normal/forwards direction until the timing mark is just visible on the left side of the timing inspection hole. Rotate the wheel very slowly until the CPS value in ECM Spy increases to 5. This is the exact point of firing. Now check the timing mark inside the inspection hole. If it is exactly central all is good, if to the left, then the timing is advanced, if to the right of the hole, it is retarded. | ||

Daveymac, Thanks much. | ||
| Davo |
Electroglider 1997, The same procedure can be done with a DVOM reading a 0-5 volts scale on the CPS connector at the ECM or you can simply listen for the fuel pump. It happens at the exact same time that the CPS goes to 5 volts. (Message edited by davo on August 14, 2007) (Message edited by davo on August 14, 2007) | ||

Is there a page that outlines what the ecm spy palm and pc version differences are? and a page that will tell the same for the vdsts? |
