Memjet Module

[guzziben47]

I notice there is a company called Memjet that is making an adjustible performance module for the Stelvio. I'm sure it's not as good as the Power Commander, but it looks like a possible less expensive alternative. Has anyone ever tried one?

If this is the device that fools the temperature sensor, then the Piaggio service rep had one on the Griso demo at John Day. The bike ran great with that and a Termignoni exhaust. He tried to tell me that it's a cheaper, simpler, way to adjust fueling. It did work well on the demo bike, but I haven't ridden a stock one to compare.

Ben, there's a couple "band-aid" options out there that you can waste $100 on. It will run different, just not much better. You get what you pay for (sorry).

Keith, that's quite surprising that the Piaggio Tech guys knowingly admitted running something like that on demos... though I have to commend them for acknowledging that they still run poorly, even with the map "updates."

He was quick to pull the seat and show it to me. I think it was after he knew Ray and I had your setup on our Stelvios. But you know what happend with Ray. I hope he's got things back together, the map update pretty much ruined his weekend.

I'm assuming that the demo bikes were 2010 models and if that is the case there should of been no need for any sort of ECU fooler to get them to run satisfactorily. All the 2010 models, to the best of my knowledge, are using the A8 motor which seems to run pretty nicely as delivered. Not suggesting that it can't be improved upon, simply that if they are set up right they run nicely. Bit of a sad indictment if the importer can't get the wee bugger to run right....

I will be installing todd's full setup on my G11 shortly, then sacrifice my fatduc in some form of voodoo ceremony

These "low tech" solutions are not good enough and eventually you are paying more in fuel as, in order to have no lean areas, you are getting too rich in other places of the map. And who knows what happens on a much colder day...

Even if you do not want to go the experienced "plug and play" way Todd offers and prefer to do your own map on some PC type accessory, go for the proper expensive devices.
Chances are you will finally be paying more than Todd's solutions except if you have a (very) friendly dynamometer that will not charge the man hours needed to produce a proper map and recheck it in different climate conditions...

I'm sure the Power Commander is better. I'm just thinking I may not need everything it has to offer. I'm happy with the power the bike has, and I can live with the dip in the curve. All I really want is the bike to run smoother. Also, I'd like something that is easy to install, and is removable if it doesn't work out. I'll probably save up for the PCV; I just like to know what else is out there....

For what it is worth, I am tech supporting a competing firm to DJ in the dyno section and I am a DJ products skeptic (ok, mostly due to personal bias ) .
So when I tell you to go Todd's way, it is not because I have anything pro to this solution except plain simple honesty.

If you go the cheap way, you can make the bike run better (not too lean after less restrictive breathing in-out) but you are not altering the map - just putting an offset to the "point normal". So the map will still be a mess, just not too lean.
If you can live with that then no problem but you can never know what really happens in your engine.
If you do heavy mileage, then chances are that you will be paying the difference in gas and still have no proper mapping...

If what you say is true, then that's pretty disconcerting for anyone who owns a Guzzi. If the manufacturer is so incompetent they are shipping these bikes with feul mapping that is a "mess," then that doesn't imply anything positive about the rest of the bike. I'm sure the guy programming the PC-V is a smart, capable guy, but if he is that much better than the engineers at the second oldest motorcycle manufacturer in the world, that suggests Moto Guzzi has some serious problems. And it's only rational to infer those problems extend beyond the fuel mapping.

Mayble I'm deluding myself, but at least for the time being, I prefer to think the problem is just the restrictive EPA requirements in the US. MG is forced to import this bike running way too lean, and with way too many other environmental add-ons. If you richen up the mixture and remove some of the add-ons, you'll have a great bike.

Call it blind faith but I'm hoping that's true!!!
