Welcome to the GuzziTech Forums - Chat & Tech from Old to New. Guzzi Power!

Rapid bike is not a bandaid at all but the equivalent of PCIII made by an Italian company. I think it is a little better than the PCIII from what I have heard but no personal experience.
Anyway, the PCV with the Autotune feature is more advanced.

Ben, again, do a search here on Rapidbike, you'll find all you need. Old news.
In a nutshell, it's a product that was reverse-engineered from Dynojet's PC. I set up to be a dealer for them back in '06, but I dropped them shortly thereafter as they weren't able to deliver any product here in the U.S., - as well they changed Importer several times in as many years. They sold a clone of Dynojet's 15RC "02-controller" that they billed as working on the 5AM, which didn't work (as per a few years ago)... perhaps they figured out by now, but Dynojet themselves have not yet. I think there has been one or two on the Forum here that have purchased one, with fair results. Pete Roper bought one, never got it, and the company has been unresponsive ever since. Caveat emptor.

Quite right. They, Rapidbike USA, took $700 or so from me. Didn't send anything. I contacted them once and they said there had been a problem getting the system to work (?Why were they advertising it as ready to go then?) but that they would send it when it had been sorted. They never did. When I contacted them again in a series of emails they either didn't respond or, when I finally got the shits, they sent me a rude email saying that they had sent me a cheque and when was I going to cash it? Needless to say there was no cheque and since i had paid with a credit card why did they need to send a cheque? A simple transaction reversal would of sorted the problem immediately.

Crooks and charlatans. Avoid like the plague. Needless to say I can't comment on whether their system works as I never recieved it. They're based in New York, I'm tempted to drop in while I'm there and put a turd through their letter box!!!!

Well, a fellow European colleague put it right: They are Italians : "Do not worry, no problem, it will be ok!" all the time...
Most of the problems I read about Guzzis come from this same way of manipulating life...
It is a miracle Guzzi is still open for business...

I guess the input from the air temp sensor must override the input from the 02 sensor or the Memjet would not work. Regardless, that is another advantage I see to getting the re-flash. My understanding is the reflash involves disconnecting or otherwise disabling the input from the 02 sensor, and it makes sense that further modifications would work better without having that in there. If that is correct, then a reflash alone should work better than a Fatduc or a Memjet.

I saw a comparison of the full monty with the fatduc somewhere on this forum, can anyone say, based on their experience, how the re-flash alone compares with the fatduc or the memjet (or even the Rapid Bike)?

I didn't mean to get side tracked with the Rapidbike thing. It sounds like nobody has actually compared the Re-Flash alone to the Memjet or the Fatduc, but the expectation is the Re-Flash should work even better than either the Memjet or the Fatduc.

I'll likely give the Re-Flash a try over the winter....

This is a pretty usefull remark.
I would love to see a comparative dyno chart with torque & AFR curves for the same bike with memjet/fatduc/reflash/reflash&PCV/reflash&PCV&Autotune add-ons.
It would be even greater to have roll on response dyno charts of some kind with each add-on.

Todd, would it be too big a hassle to give us all these on the same bike/same day and leave no one unconvinced ?
It would be nice mecha data too!

Is the Memjet module similar to this? www.boosterplug.com

I know a few people on the Tiger 1050.com forum have fitted it and think its OK. However I've never thought that my Tiger ran bad enough to need fitting anything like that, the same with my Stelvio it runs fine, although I can't wait to see how it feels when I have the Quill end can fited.

Just out of curiosity what is considered to be the ideal Air Fuel Ratio on a Stelvio? I've been reading this thread over and over but I have to admit I find difficulty understanding all this fuel injection mullarkey. At times I wonder if it would have made for a simpler life if we all rode around on old four stroke singles with an Amal monobloc carb

A previous post http://forum.guzzitech.com/forum/190/4957.html?start=50#p37784 has the basic theory on internal combustion engines running on petrol. This covers the basics.

The Booster Plug looks like yet another way of doing it. The Memjet is similar.

I wouldn't bother with any of this if your are already happy with the bike the way it runs now.

And none of this has anything to do - in my mind - with convincing anyone to buy one thing or another.

If you want to see a dyno chart, there is one for the Memjet and the Stelvio at the website for Memjet Modules.

I'm happy with just the Memjet for now, but I'm going to try the Fatduc too, just out of curiosity. Then I'll get the re-flash and answer my own question....
