The numbers are the same in English and Italian😁
I do know what you mean but. I just google translate key words. Funnily enough after a while you start to sort just know what's going on. Sinistra left, rosso red, temperatura temperature etc, and away you go.
I always found Sinistra for left kinda reasonable. It was explained like this. We shake hands with our right hand. Apparently this because most people are right handed. If your hiding a dagger in you left hand (sinister person), the chances are the stab will be less effective and give the victim a better chance. Probably explains why we Lefties so much crap, but don't really why other than they hold pens seemingly strangely. 😄

Guys
as I am away from my bike and physically can't test anything, I was wondering if anyone can shed some light on the original problem of not being able to communicate with the P7 ECU? My mechanic originally suspected a non standard eprom chip, but that has now been ruled out. What type of terminal/programmer should be able to communicate with the P7? From what people have mentioned on this thread previously, there are no diagnostic functions available but I should be able to download/view the fuel map?
Once again, any help would be greatly appreciated
Thanks

Vulcan mind meld is about your best shot. The P7 is a primitive beast. If all your sensors are working as advertised, throttle bodies set up, no air leaking from rubber manifolds,valves sealing etc, then changing the chip is about it. The best anyone ever did was FIM, he added another small board that allowed mapping changes. There are a couple of power commander type products that piggy back on to the injectors to change fueling out in the market place.

the guzzidiag guy told me that ducati didn't activate the diagnostic capacity on the p7 eproms, whereas guzzi did.
he did send me a guzzi daytona file, but i've never bothered (had time, motivation, etc) to try it. allegedly you can connect a guzzi p7 to the diagnostics and it works just like the p8 does. even shows the electronic step count of the 4 turn idle trimmer.

At the risk of annoying everyone with my constant stream of questions, can someone clarify if the SP2 came standard without an airbox lid? I had a discussion with someone today who mentioned that removing the airbox lid would result in a leaner mixture, but I would think this would affect it over the whole rev range?
brad black
pretty sure they didn't have a lid, but wasn't around them when new. 3 certainly didn't.
it's not the cause of your issue. it sounded to me like you had a soft primary injector.

Wether the bike came with a lid or not , there are plenty of people here running engines without lids. Like Brad says , it is another problem. Have you completely checked the injectors running at 3.5 Bar ????
brad black
these things had an air pressure sensor in the airbox too, so if it raised the pressure at all it'd be reflected there.
i ran my 888 with and without (with std mufflers) and it didn't need more fuel without the lid in terms of power production. so maybe it was compensating somewhat.

My SP2 did not come with a lid-- it was an open box with a filter on top with a metal picture frame held down by four short snap-over clips.

My SP4 has that , because I fitted it and it runs like hell.

Can someone confirm which way the CO trim pot works on the P7 ECU, I've read conflicting advice; clockwise or anti clockwise for a richer mix?
Thanks
brad black
pretty sure it's anti clockwise.
fnqal
Thanks Brad
I have now bumped the fuel pressure up to 3.5 Bar and moved the air temp sensor to the front of the bike, underneath the dash. I haven't had a chance to take the bike back to the workshop yet and check the A/F ratio again. I have also purchased a Fast by Ferracci stage 2 chip that should arrive by the time I get back from work. I'm hoping that the higher fuel pressure and relocation of the air temp sensor will do the trick, but purchased the FBF chip just in case!
brad black
oooh, stage 2.

brad black wrotepretty sure it's anti clockwise.
Brad-- why does my old brain recall that you can keep turning the trim pot and it will go from 0-5 volt and then start over. I dimly recall that I would use a DVM to set it at 2.5 V and then use and O2 sensor to track the change-- I think you had 1 1/2 turns in each direction before you started over. I have no idea why I remember that this happens with the trim pot-- so I could be wrong.

you have some reservations about a stage 2 FBF chip lol

it rolls over at each end of the travel with no further change - 2 turns either side of the 2.5v centre point.
from memory - to reset it you have to go at least 4 turns in the opposite direction i think

the whole stage thing just makes me laugh. it's like the old "3/4 race cam" back in the old school days when the race stuff was the cool stuff and that just meant really big, but not the biggest.
depends also what is changed. these eproms have ff on the original fuel maps. there is no bigger number. you can go around that with the environmental trims tho.
send it to me and i'll tell you what's different.

Thanks for the explanation Brad. I'm back at work at the moment and won't be back in Aus for a couple of weeks. I would be very interested to know what is different from the standard chip

Hi Guys
just a quick update on my lean running issues. Fast by Ferracci were kind enough to send me a couple of eproms for my bike, both Stage 1 and Stage 2 chips (apologies Brad, but I had to name them!). I had my local Ducati mechanic run the bike with both of them on his dyno to check the A/F ratio. The first one still had the bike running lean in the mid range but the Stage 2 chip has the A/F ratio between 13 and 14%. I am much happier now that I know the engine is fueling like it should be. Thanks to everyone who offered advice on this issue. I took the bike for a run yesterday on our local range (The Gillies highway) and I couldn't wipe the grin off my face the whole ride. The induction roar on the SP would put a horn on a jellyfish!!!!
