Yeah i knew where you were heading... same as i just did on my smart Laughing

Luckily enough the fuel pressure regulator on that is a direct swap with a VW one just with another 0.4bar Twisted Evil

Have you had the ECU notice the extra air?? I wouldve thought it wouldve been capable of adding enough fuel to compensate for the better airflow of a ported head?? If you have had it happen i guess the little injector is near maximum capability and doesnt have enough in reserve... Ive never played with a GTS yet so dont know. Glad you lot are happy to do so! Very Happy

Ill have to find the dead pump ive got and see how would be best to up the pressure... im still not 100% convinced you cant get a bigger injector though.. im sure one will turn up oneday.

As another thought, could you trick the air temperature sensor into thinking the airs colder than it really is so it richens the mixture a little as well?? Might help if your right on the limit of fueling...just ideas from playing with cars really.

The GPR box is like a Power commander really, but mechanically adjustable and a lot less prone to failure! Laughing

The posher one has 3 range adjustments to let you fine tune it a bit more? Ive been waiting for my 3rd PC3 to blow up and then i might try one myself Laughing

Phil (smirnoff) runs an open filter which threw up a fault straight away until the PM box was adjusted to almost it's max.
The injector would be my first choice but can't get the info out of webber but the folks I spoke to were Car folks and had never heard of the injector thats standard on GTS's.
The valves and porting took our 210cc runner from 15 to 19 BHP(rear wheel) so the GTS will notice it alright. Smile

I'm sure something will present itself.

Don't Ducati use webber injection?
I just need to talk to the right folks and it'll get sorted I'm sure.
The Webber part number on the stock one is IWP 152 or IWP 182 (I can't make it out clearly) but Webcom know nothing of these.
If I could get flowrate info maybe I can go get something else that'll do it.
Any info out of Piaggio is very hard to obtain unless someone we know is going over for training and can ask unofficially.

Using the enrichment cycle is a good idea but a bit rough maybe.

Still, chin up meself, it's only my second day in the adventure and I've got a week til the head comes back!

You just remind me, Iv'e got a dead pump somewhere too!

Yeah and Webcon are big weber dealers... being a IWP injector its just a std PICO one so once you get a flowrate of the original a replacement should be easy to obtain, i guess its piaggio making them use a odd number to try and stop the tuning people Rolling Eyes

Gonna phone Oz today and chat.
And a number of other folks including an ex lotus trained ducati works mechanic.
James came back today after the Injection course tuesday and wednesday.
I'd forgotten half the GTS stuff so had a refresher chat with him.
Also he did a bit of diggin for info while he was there.
The Piaggio training guy who is the funniest teacher I ever had, pointed to his overall badge and said "This says Gilera, It doesn't say Malossi."
But James got the info anyway after side stepping him somehow.
I'm very confident we have a source for the perfect Injector.
Or an uprated pump whichever way we go.
My favorate at the mo is the pump because the GTS will always be able to cut injection time, it's the increase thats the problem.

The GPR boxes arn't in country yet so PM one should be here tomorrow.

I have an upgraded injector now so we are nearly all set.

Got one only the other day for a big bike anyway!

And yes, Piaggios training man, Adam is a great laugh! Were you there when the MP3 seat?? Now that was a very funny day! Laughing

All you need is a dyno now Russ, cant you shift Gaz over a bit and have a ramp installed.

I don't see me needing a dyno after the first couple of conversions.
I'd rather travel to the one I used before even if I have to go ten times it's way cheaper than buying one.
Dyno would be redundent before long, I wonder how many hours dyno's are used at PSN and PM.
The Dyno I use is mainly used for track bikes and they come from far and wide but I can still book an appointment pretty much when I like for as long as I like.
Dyno's take forever to pay for themselves.
Much better to van every scoot converted up there and pay the £30.

How's your going Phil?

Indeed Dynos are expensive things and its far easier to use someone elses.... we had one in our Norwich branch before we closed it, and the only time it really got used was at the weekends when we did power runs for £10 a go... other than that it was used once in a while but never even got close to paying for itself...now we just use another one locally and its fine... theres never that long a wait for it.

And like ya said, unless your after ultimate power possible, once ya got it sorted on one bike, just use the same settings etc on the others and they will always be 99% right, which is enough for most.

Weve never really got into heavy scooter tuning, i would like to ride one, one day just to see what can be got from them..
