ducati monster black box ?

Friend has an 01 Ducati Monster 900. ( I think) its been running very
rough and rich. he took it to the local D dealer who plugged it into his
diagnostic computer. Verdict was "black box stuffed, couple of thousand
$ to replace, have to get genuine part, could be months to arrive".
is this a load of shit ?
Anchovy.

 

I've been saying they are a load of shit for years...

 

They have sold enough Monster 900s to expect that there might be a
wrecker with a used ECU somewhere in the country. Before spending any
money, the best thing to do would be find someone else with a Monster
900, swap the boxes over, and do some testing. Tell him to check the
forums if he hasn't already. On a bike that old there should be a fair
bit of anecdotal evidence from other owners who've gone through the same
issue.

No it's on the money......There is however a chap in Oz making replacement
items for under $300. Hard to believe I know.

For that price you get a heap of components and a cct brd. You also get
instructions on how to assemble the unit.

You can either buy the kit, an exchange unit or a whole replacement unit for
under $ 700. depending on your level of electronic assembly expertise.
Unfortunately though, that's not the end of it. Then you have to modify the
map to suit your bike. It comes with a Guzzi 1100 sport map which will
require modification to suit a Monster. All internal parts (except the main
IC) are available from Dick Smith or Jcar and are all identified to allow
ease of replacement. If the main IC fails it is only available from the
manufacturer.

It's not ideal but it is cheap, locally made and supported.

I have purchased one for my 748, in lieu of a power commander, but have yet
to work out the map required so it is as yet still in the box and my 748R is
still a pig in town. On the track however above 5K RPM all is forgiven.

I'm a carby man at heart and will probably throw my arms up and pay a EFI
wiz with a Dyno the bucks to map it for me.

Let us know how he gets on. Is he in QLD?

Best of luck

yes, Nth Qld.

Can he sort out the mapping with a power commander?

What sort of sensor does it run ?
souldnds like a good clean would be more use than a guess at the box

 

Yeah - that was my thought too. Most likely cheaper and probably
better result, especially if the bike has had any changes to the
exhaust or stuff like that. PC, dyno and a couple of hundred dollars
of tuning time. Certainly transformed my busa.

 

I recently was having all sort of problems with the race car and it was
suggested an electronics problem , the controller is one I built from a
kit but uses a maf which when cleaned solved the problems , I suspect
the tps might well be at fault and has to be a good guess.( and cheapera)

 

Will a power commander completely remap the injection or just modify the
existing mapping by using an overlay? If the existing mapping is
erratic (some sort of hardware/software error as suggested) how will a
mapping overlay deal with that?

I can't answer that question directly as I don't know whether it
bypasses the original ECU or not. I would think it would but as I
didn't fit the PC I really don't know. However, when I picked my busa
up in Melbourne it was coughing and spluttering like a coughing and
spluttering thing. Which it hadn't done when I was over there the week
before taking it for a test ride. I bought it from a bike shop in
Ringwood and on the test ride I liked it but the brakes were fucked
and front suspension felt weird. We stopped and realised that the
front forks were leaking and pissing fluid onto the discs which is why
the bloody thing was hard to pull up. So I said I'd buy it but they
had to fix that first. I flew back a week later to pick it up and when
I left the shop it was running quite bad. I thought maybe it was just
not liking Melbourne peak hour traffic on a hot day and fuelling up.
I've had that problem before (hello both VF1000Rs until they were
modified). But when I got back to Tassie it was a cold morning on an
open road and it was still behaving badly.

I took it straight to Red's Motorcycle here in Hobbit-town as he has
the only bike dyno and he spent time remapping the standard ECU but
really couldn't pull it in.

So we went the PC route and bingo! Sweet as.

What I could never figure out is what changed on the bike from when I
took it for a test ride and to the day I picked it up. I'd hate to
accuse a reputable bike shop of dodgy practice, but I've always
wondered whether it had a PC on it when I test rode it which was then
removed in the week before I could pick it up. The bike had a full
Yoshi kit on it and obviously the standard ECU was not capable of
handling the different airflow.

 

... you're talking about Peter Stevens, not a reputable bike shop

It changes the values going to the ecu. If the ecu has an intermittent fault
it won't fix it. But if the mapping in the ecu has gone haywire and isn't
changing it will.
