TechnoResearch VDSTS
Vehicle Diagnostic ScanTool Software (VDSTS) and interface cable from TechnoResearch finally arrived last week. So far I've had not much time to play with it, but it seems to be a tool well worth the money: in addition to normal diagnostics (error codes etc) you can reset the TPS, adjust the idle fuel trim and perform active tests on injectors and fuel pump.
I did reset the TPS on Norge, even though there was no real need - idle position was 4.0° before the reset, now it is 4.7°. Odd thing is that the reset had a bigger effect on max throttle: 82.3° changed to 85.0°. Update: 4.7° (+/- 0.2) and 85° are manufacturer specified figures for min and max TPS.
Before reset:

Hi Pexi
My 1st question is are you british. The reason I ask is that your english is extremely good & I cannot tell. I'm curious.
Secondly I am about to take delivery of a Black Norge GTL to replace my Spada 1000. I have always done my own maintenance & repairs but not on such a modern bike ie with fuel injection. I am interested in the VDSTS as this will help in doing maintenance etc. Could you point me in the direction of where I could purchase one cheaply (the Norge is consuming all my finances!!!!)
Keep up the good work with this site as I've found it really interesting.
Sorry to hear about your recent incident with a white van.

This is interesting!I've been looking for one, but since the Swedish importer would like to charge me €400 for the single-model one, I just didn't do any more for the time being. Maybe somebody could send me one from the US as a "gift" (VAT and customs are not welcomed)
How does it work? I.e. will correct values be pre-installed? Will factory-announced changes in settings be downloadable?
Tell us more, tell us more.......

Pexi's reply: Anders, I sent you email that includes contact info to German importer befaster.de where I bought mine. They are a lot cheaper, I'd say.

Hi there,
I got my Norge !! 1000 kms onboard. It is definitely a great bike.
Could you explain a little more what is the TPS and why you use this VDSTS thing ? I'm no expert in this matter so I need help.
Did it improve engine's torque or power, or reduce fuel consumption ?
Thanks
Pexi's reply:
Bruno, TPS is a mnemonic for Throttle Position Sensor, i.e. a potentiometer connected to throttle "butterfly". It reports the throttle position to engine management computer and is one of the main fuel mapping factors. Real physical throttle position and TPS need to be syncronized, otherwise fuel mapping will be incorrect. In practice this syncronization aka reset is activated with VDSTS (in our case) - official guzzi dealer typically uses a tool called Axone instead.
It has no direct effect on power or torque - it's just keeping the bike in good tune or regular maintenance, so to speak. A bit like setting the valve/tappet clearances.
