\I am going to try and put it in 6th, spin and find tdc somehow and let you know the clearances.
Can't really see the stop screw, or rather if it's been buggered with. Can you get an Allen key into it? If so it may of been screwed around with. The one pointing to the left is the bell crank screw. This does need to be adjusted from time to time.There are numerous write ups, probably at least one by me, on this board about how to go about tuning a W5AM equipped Guzzi, do a search.What is important to realise is that playing with the map will achieve NOTHING unless the engine's tune is correct. The valve clearances MUST be spot on, the throttle bodies balanced correctly and the TPS and trims zeroed otherwise you aren't going to get anywhere.Valves should be set at 4 & 6 thou cold.Pete
Roller engine clearances are 0.1 and 0.15. The 8V is very sensitive to valve clearance changes.Does this dying at idle persist when the engine is warm? Or is it only apparent when cold?Pete
I had a Stelvio recently that was cutting out at low speed and it turned out to be one of the fuses under the small triangular panel on the right below the rider's seat. As the power was cutting in and out it triggered a phase sensor error but replacing that didn't cure it. Removing, cleaning and adequately seating the fuses did. Just a suggestion.Pete
Finally got GuzziDiag working. Turned out to be user error. Misinterpreted the directions the reader gave. Reader said if you hear the fuel pump, restart the program. Since the fuel pump comes on with the kill switch disengaged and key to ignition, I took that to mean turn the key to ignition with the kill switch engaged. Since that will prevent the fuel pump from coming on. But that was not the case. I needed to have the kill switch disengaged before I turned the key to ignition. Found all of this out after creating an Ubuntu virtual machine which exhibited the same behavior as Windows did i.e. Adapter Test succeeds, but Reader or GuzziDiag cannot connect. Frustration forced my hand... and it worked Going to try it out on Vindows tonight. The performance of the reader on the VM was un-acceptable. Too many damn bridges to traverse.
well need to read is once, writing is much faster, 5 minutes
And sometimes that is what is needed to isolate the problem.Really, from half a world away, there isn't much more I can offer in the way of help.Pete
Got data too! So far so good. However, I can see that the TPS is way off. Where I'm stuck is the reset. I can go to the Actors page, but with the engine off, the Actors is greyed out, but accessible with it running. Clicking gives me an error.
Can anyone tell me if DucatiDiag is still available for download or do you just use the IAWDiag and choose the correct ECU. I have a friend that is interested in it but I can seem to find the downloads other than some old references that it is not available. The XDF are still on the Guzzidiag site for Ducati so assuming it is still living somewhere. Have not really followed the Ducatidiag story so apologies if it is well known information.
when you fresh connect, with engine off, and then goto the actors page, is still all greyed out?
I could be completely wrong here, but doesn't the TPS on a Breva 750 have slots to allow for manual adjustment? I was once fooled by TechnoResearch documentation describing how to read and reset the TPS using the "Alfalin_0" channel. This was for a California Vintage.After much frustration I found the TPS had to be adjusted manually the old fashioned way, i.e. rotated to read 150 mV with throttle screw out and linkages removed, and then winding the throttle up to the prescribed amount (for the Vintage, this is 485 mV).The Breva 750 uses the same Magneti Marelli IAW 15RC ECU. I suggest you check for adjusting slots on the TPS.
Yep. Greyed out. Tried a download of the .bin file (Map I assume?), but it seems to be empty. And it took seconds, not minutes!I don't like the smell of this...Edit:-Had another go. This time, I got the Actors - TPS reset, clicked and got Actors OK. Throttle still says 7.9HOLD THE PHONE!!If I try the other throttle reading it says 3.1 - as it should.Too dark and cold to try it out now; here's hoping for tomorrow morning! Thanks all.
But what is exactly wrong with the bike?
what ecu does he have? But iaw-diag should do it. and for 15m and 5am the normal reader writers. For 5.9m the writer is nearing completion, and the reader is there. On the downwload page I posted a number of ducati xdf files, but the good guys at Ducati make a different ecu layout for almost any bike. Sometimes using a bike that is near specs works.
Let me start by saying that with Paul's guidance and using one of Beetles, maps my Stelvio is running absolutely fantastic. No vibes, better mileage and a much smoother power delivery. But now that the cold weather is upon us I have one little niggle.1st start from cold, it fires instantly, then sometimes dies. If I catch it on the throttle, and manage to keep it running for 10 seconds, all is ok. Otherwise i go through this cycle of start/stall/start/stall until I do catch it(only 1st start and only on cold mornings) If it were an old carb'd engine I would say it needed a bit more choke.So . . . As it runs so perfectly i don't want to mess with the main map, but I notice there is a warmup map when viewed in TunerproDo those who know more than me (everyone!!) think that by upping the fueling within the warmup map will help me, and if so by how much? 1 point? 5 points? in every box?
