I think that it's great that the ECU can be re-mapped by the owner. After skimmimg the forums, I would say that there has been a lot of hard work and support put in by eg. beetle and various others over the years, and this makes for a much more satisfying owner experience.
With most bikes a re-map is a purely financial process! |

You have to remember that when these plug and play units were in their prime, remapping was neither simple or cheap.

Still don't understand why people go for those plug-n-play units, when it's cheaper and better to load another Map.
Think of it this way; You have a stone in your Boot, it's irritating you, do you; A. Put a couple of pairs of thick socks on the affected foot to make it bearable (the plug-in thing)?
B. Remove the stone (Re-Mapping)? Running with something that just richens the mixture can f**k up your Pistons, Rings, and Bores, the extra Fuel reduces the Oil film on the Cylinder walls. Pete Roper (you may have heard of him?), has pictures of a set of Rings sat inside the Bore of an Engine that had one of these things fitted. The end-gap was massive, due to the vastly increased wear rate, something like 10x what it should be. |

Yes snatchiness just about describes it. You'd think they'd put a soft action throttle cam on a tourer. Mind you it makes it easier to blip the throttle for a down-change!

G2 Throttle tamer. Works a treat and eliminates about 70% of the snatchiness.( not sure if that's a word)
Or you can save yourself a few quid and use a Stanley knife to reduce the curve on your original throttle cam. I tried everything on my 2014 Stelvio including new maps. The Throttle tamer was the most effective.

Best thing with maps is that the wiring remains original. If for any reason, one wants to restore factory state, its a 10 min job. Assuming that iawreader was used to read and backup the factory map, before loading the new map with iawwriter

I've decided to go for a Beetle Map. I've been impressed by the support he gives on various forums, and the offer to tweak the map based on my feedback.
With the other modern bikes I've had, I just bought them and drove them. The Guzzi is a much more "involving" experience. |

I spent two years trying to get this fixed on my Griso and couldn't. So I sold it. I imagine you'll be wanting one of those Finebeau (sp?) thingies.

I assume you mean griso.org. I've sent him a message, to see what he suggests.
Cheers. |

If you have Guzzidiag go to www.guzzi.org for a new map - no I have no connection other than a great improvement with one of beetles maps

Yes I'm going to check the TPS settings. This is an absolutely bog stock 2013 Stelvio. I think that the Finebau unit tricks the ECU into richening the mixture at low rpm so I guess I should be able to do something similar with TunerPro. I'll try griso.org for more info.
Thanks. |

Since you got guzzidiag, the first and easiest thing to do is to check the throttle position - closed throtle should show 4,6~4,8. The second easy thing is to go to "actors" and reset the tps - if the reading is not correct.
About maps, you can load with guzzidiag (iaw writer) you can ask "Beetle" at griso.org, I think he'll need some info about model year and exhaust you have, maybe he won't want to deal with a non-roller tappet bike...

Yes I looked at the Finbau unit as a possibility, but as I've got Guzzidiag I'd prefer to get a map from somewhere and load it. I understand that maps can be changed with TunerPro, but rather than spend hours doing research I'd prefer to beg or purchase a .bin file that was customised already.
Essentially this file would only need to soften off the throttle response between closed throttle and approx. quarter open. Someone must have done this before. |

He is right about it running lean. My Norge was he'll on wheels until I fitted the Finbau unit that fools the ecu in running a little richer,never looked back after that

Thanks for the feedback. I'll check these out. Where I'm coming from is that the mechanic who I deal with suggests that most modern bikes are set too lean, in order to get round the emissions reg.s. He has tweaked the fuelling map on a few bikes and got them to run smoother.
I'm wondering if people have had the map changed and got a good result. |
