Thanks for those responses, which despite being slightly mixed, have the majority saying don’t use this thing and get a re mapping of the system.
It’s a single throttle body (VIN – ZGULWG008CM11569 Engine # 12894) and despite not being registered until early 2014, may be a 2012 model. Anyone want to confirm that?
I don’t know that there’s ever been a re mapping and I can’t find the original owner. Number 2 bought the modulator so it seems that he didn’t try this better approach.
I had to go to Brisbane to pick it up and there was a cyclone bearing down – the rain dump of 300mm was in full swing, so wasn’t able to spend much time with the seller trying to get all the details of the bike’s history. Not the best buying method.
If there was a need for re mapping to get the engine running better, then why wasn’t this a Guzzi (dealer) service offered to owners in the same way that cars get a recall notice if there is a defect. This bike is now outside its warranty period so that would complicate things and give the dealer an OUT.
So this seems to be an option:
Quote “ I downloaded Paul's Guzzidiag, installed a map from Molly here- bike runs great. Get Guzzidiag and cables, give Paul a donation, and do it yourself. “ (boat detective) His was a 1200 S so is the same option available for the 750.
But “cables” –can someone clarify because getting US postage is a hassle. And point me in the right direction to find ‘Paul’. I have a very electronically smart K mate who could do this,
But maybe he’d want to talk to one of you guys first.
One thing I will do, is put the original lanfranconi pipes back on because its got a set of Pipemasters ( which don’t seem to have much baffling) and see what this does for the running. I have to do this in any case because for the ownership transfer I need a RWC and there’s no way any bike shop is going to pass these pipes.
I read the suggested thread - http://wildguzzi.com/forum/index.php?topic=74827.0
But if there are others, then can you point me to them. The “search” doesn’t give me anything, nor does GOOGLE.
Randown says ‘PLUS if your bike has a lambda’
Vasco D G ‘While the single lambda smallblocks seem ‘
What’s this lambda? I thought lambda was a scientific expression of the optimum relationship between fuel and air for an engine.
Do these O2 modulators just work in a similar fashion to ‘chipping’ a diesel engine, where with the crude ones, all you’re doing is increasing the fuel delivery pressure, to the possible detriment of the engines longevity?
So thanks for the contributions. Seems like I have a bit to learn but as I’ve found out in the past, this is the forum where you get some good help.
