Title: guzzi v7 stone ii fuelling
Post by: chrisk on March 19, 2016, 06:32:30 AM
Hi,   I’m looking at my options for tuning the fuelling on a v7 stone ii -  I’m sure this has all been asked before but I couldn’t find a complete post that says it all.

1 – Do Dynoject/PC actually supply a model for this bike, I know they did for the earlier 2 body fuel injection model but don’t think they do for this one?

2 - The GT-Rx tool from guzzitech looks good, but as I’m in the UK I want something that I can get my local dyno centre to update if need be. I’m guessing this is a US/proprietary tool, not one for general use ?

3 - Are there any other options for v7 II fuelling tuning than those discussed above?
 
4 – I get what the booster-plug and GT-02 optimiser on guzzitech do, question is are these redundant if you get one of the above devices

Keep on eye on Guzzidiag. The MUI G3 Writer's being worked on. See http://www.von-der-salierburg.de/download/GuzziDiag/

Option #4 has an extremely good chance of destroying your engine, at least any of the O2 sensor foolers may. The 'Booster Plug' crap is I believe an air temperature sensor fooler and if so the ECU will just trim around it in a few hours.

Booster Plug and Accelerator Module are temperature sensor foolers, and at least some ECUs (e.g., BMW Motronic) will "learn" them and readjust to defeat them. I run an O2 shift device (AF-XIED) on my Beemer which, as I understand it, does not fool the O2 sensor, but works with the Motronic to enrich the mixture by an adjustable amount. All I can say is that the bike runs noticeably smoother and stronger with this device.

I've got a Finebau fuel injection compensator on my 2015 V711 stone and its been a worthwhile improvement during small throttle low rev conditions. Steve.

I run a MyECU programable ECU from Australia.  A nice unit if you like a hands-on attitude, but I don't believe that's available for the post-2013 bikes.

Yeah, like the Dynojet/PC, I can't imagine how that would apply to the 1TB models where the ECM is physically integrated with the throttle body itself.

Like you can't piggyback to it, you can't replace it without the whole throttle body and sensor assembly.
