I put in a new TPS sensor on my 2004 XB12S. I wasnt able to get ecmspy to link up to my bike correctly so I wasn't able to do a TPS reset. Is it absolutely necessary to do a TPS reset when replacing the sensor? Cause I started the bike up and it seems to be idling correctly and running fine. If I have to have it reset than I can take it to the local HD shop, they quoted me $43 to do a reset. Thanks. | ||

It's not absolutely necessary and you could ride it like that. I have always been sketchy about dealer TPS resets. They rarely get it right the first time. Keep working on getting ECMSpy connected to your ecm. It will save you in the long run. | ||

so what are the risks of riding without resetting? | ||
| Terrys1980 |
None really. It can't damage nothing except maybe foul plugs?? If the TPS is off the ECM will read the wrong cells of the fuel/timing maps causing poor performance or it may not run at all. | ||

Unless it's too lean or the timing is too far advanced. BOTH of which can damage an engine in the heat. | ||

You will definitely hear some pinging if that was the case though and hopefully you park it right after. | ||
| Slaughter |
Depends on how far off it is. You can be extremely lean and not really "feel" the power loss. The map is SET by Throttle Position and RPM. | ||

Also - if you are getting some pinging because timing and fuel are off at say 6500 RPM, you may not hear the pinging. Pinging tends to be more obvious at lower RPM with less background noise. I'd just be careful when riding a bike without knowing how far off the throttle position is reading. Wouldn't have to be that far off to be pulling ignition and fuel data from the next column in the table. | ||

so what you are saying is... take it into the shop and have them do a TPS reset? or... anyone in central IL wanna assist me with a TPS reset? | ||

If you can get somebody to do it for you on ECM Spy or take it to the dealer you would do well to have it done. If not, you might get lucky and it'll be close... if it's not close, you'll be hoping that it's so way far off that you'll feel it. I didn't feel this or hear any knocking. I got a black flag and when I pulled in and slowed to a stop, it became obvious with the smoke caused by the blow-by. Motor going back together tomorrow. Racing again this weekend AFTER I verify all is good on the dyno.  | ||

I'd like to get ECMSPY for my bike, but I don't think they have a Mac version. | ||

I'd be happy to help you out, but I'm a few hours north of you in Carol Stream. I also won't be back in town until about August 8th. If you are still in need at that point shoot me a PM. | ||

They do not. Do you run a virtual machine at all? I run Windows XP running under Parallels and ECMSpy works great there. | ||

Should be ok, if it was not real close bike would not start and idle. Get it done proper is best of course. |
