We all sorta realise EFI can be good if you live on a higher plain or up a sacred mountain.
BUT, how complicated will it be to tune the system on the GTS compared to a GT with its carb?
I worry a bit that some workshops will have problems coming to grips with it equipment needed etc.
If it is easy well I'll be stoked as it will be a tuning facet, but I would like to hear from some of the professionals in the group.
All the Best for the New Year to everyone.

gts EFI
all service facilities here in the usa have been supplied with the diagnostic device for the efi. i just had my device programmed for the gts. the gts seems to be very a reliable system.

Thats good
Thanks Ramrezz for that info. Is the device you mention a very expensive item for a small shop to get,we may find in NZ its a biggie or does Piaggio supply free or heavily subsidised to accredited agents?

As with modern EFI cars, It will probably be a self correcting system.

Meaning, as the scooter needs more fuel it will get it. The DVD we received on the FI system said (in mechanicall translated english) that it will have a re-programmable EPROM. which is the term that makes VW mechanics smile maniacally .

I see some chipping happening on the horizon, then. And thus, a whole new facet of tuning arrives for the scooter crowd.

Well, well, well. So the GTS has electronic fuel injection? Chips for scoots on the way...?

Does it come w a data port--? So we can envision handlebar-mountable digital performance diagnostics any day now-- Like the Palm Pilot VAG-COM readers for auto-modders, e.g. >> www.pocketlogger.com

not too far off I would suspect...

but you adjust whilst riding. I'll adjust then ride, then repeat.

diagnostic device for gts
is merely a diagnostic device. the issue of chipping did come up but the gts is so new that i suppose the aftermkt will have something soon. hopefully everone will be happy with perfornmance of the gts right from the factory., i was when i rode it. i would prefer a louder pipe though but there are a couple of people that i trust their judgement upon that did not like aftermkt. pipes for gts. if you havnt rode the gts yet your in for a treat anyways since there are performance differences from the gt200.

location of docking hookup
gts has built in hookup up located on the wireharness just under the seat and you will see it on the right side after you remove the bucket.
bv200 and x9 500 have this too.

Methinks that even the 4-wheelers with laptops plugged into their highly modded rigs ride, adjust, repeat--

How 'bout this: Once we get the Pocket Logger hooked up, we'll ride 2-up; I'll drive, you adjust, then we'll rocket off into the stratosphere-- 8)

I haven't been too much into the "modding/logging" scene, but I'm always up for a reverse engineering challenge (for fun of course). From what I understand, it shouldn't be too difficult because of new US laws prohibiting "car makers" from "locking" out people from doing their own maintenance. How it applies to an Italian Vespa Scooter, who knows.

When someone is ready to begin, I'll dig up my notes for serial loggers and "secret sauce".

There are some who will never be satisfied with the compromises that had to be made to create a salable product. And there are some who simply cannot leave well enough alone.

Forgive me, tech pros, for what's no doubt naive enthusiasm as I scramble to catch up-- & thanks, Old Mod, for the thread-- I love all that I learn on this forum.

So here's the scoop >> Chipped scooters are here! Disclaimer: True techies, feel free to make additions/corrections--

So, in this New Land of electronic scooter/motorbike technology, my quick web search tells me that those crazy Italians are leading the pack. First, Malossi's got the performance kits for non-EFI covered. Guess who makes the ECUs (electronic control units) for most EFI bikes and scooters? Magneti-Marelli.

Need more than stock? The Italians have it for you, with a device called Rapid Bike http://www.rapidbike.it (click the English version, upper right)

Got a Piaggio or Aprilia scooter with EFI? With Rapid-Bike you can hook up a modified ECU & software, linked to the OBD (On-Board Diagnostics) port, that lets you do performance tuning on the fly (Larry, it's true!), like making changes to the spark timing, RPM limiter, etc. And, yes, you can hook it up to your Palm Pilot or other PDA to display the data 8)-- Marketed in N. America by http://www.technoresearch.com

Magnifico!

shush
If you want a tuned pipe with efi , I believe you have to learn to disconnect the sensor in the standard silencer.
Its gonna be a can of worms and I'm going to be relying on you clever dudes to get it done should you choose to accept this mission.
This is purely for my wife's GTS you understand.

Dynojet Research has been producing companion ECUs for motorcycles for a few years. Their PowerCommander PCIII has a built-in USB interface for connecting it to a PC.

My personal opinion is that ECU tweaking is over-kill on a small displacement, single cylinder, engine. There just isn't much to be gained, with potentially more to be lost, in modifying the stock maps in this application.

I agree, but I don't think that'll stop people from doing it anyway.

do it in conjunction with
increased displacement
freer flowing exhaust
freer flowing air cleaner
upgear when its available.

every gain is still a gain..

Sorry, my first attempt at this post got mangled. I temporary lost WiFi signal. This is my whole post:

Yes, a gain is still a gain, but look at the cost. A pipe and ECU replacement will run an average of $300 each. You may gain around a HP, and you may loose a smooth power curve.

True but
Yes people will fiddle and can lose reliability.
A 2hp increase even on a scoot is very noticeable on the road though,
Do those members with PM pipes on their GT200's notice the claimed 1.8 hp gain?
Maybe this should be a new thread,?

I had to learn (car) tuning all over with my WRX. I was used to fiddling with valves, jets, cables, timing lights, etc. Adjust the tappets or the carburettors on the MGA? No problem. Tweak the timing? Easy as cupcake.

Then...

Add a resistor to the second O2 sensor and replace the EGT sensor with a diode to fool the ECU into thinking that the first two catalytic converters were still there, and that EGT temps were within spec? Huh???? At least I used a manual boost controller rather than the electronic piggyback units. This sort of stuff baffles my head. (And all that is without even getting into aftermarket ECU tuning kits!)

Hey, Steve-- My first car was a '68 MG Midget-- did the tune-ups. The Audi TT, like your WRex, was my introduction to the world of chipped tuning, &c. I make no grand claims to expertise, but like knowing that there's another world of techno-possibility out there-- The ET4's my entree into the land of scoots/bikes-- & once again it tickles me to have new stuff to learn about-- mind you, at this point, my Italian lap robe's my most radical mod -- (well, maybe having my Joe Rocket gloves wired counts for something, but I think I'll wait for my skillz to catch up b/f I contemplate tweaking the ET4's performance much).

Still, I get a kick out of seeing what's possible-- hi tech, lo tech; old skool, new skool-- it's all intriguing. For those of you who don't leave well enuff alone: you've got an appreciative audience! 8)
