Potential New User and Greetings
Evening all - a prospective new user here
Let me set the scene - I ride a 2005 Moto Guzzi Breva 1100 with a 90 degree V twin (odd fire I think)
This machine is fully fuel injected (Magnetti Marelli IAW 5AM) with the "feature" that the immobiliser and the atmospheric air pressure both come from the dash
The other part of the this feature is that the dashes are prone to moisture/water ingress so when you loose the dash you loose the bike, unless you can find a new dash (circa £1000 ) or a secondhand one (typically £300) which sooner or later will almost certainly die.
The bike comes with standard Magnetti Marelli inlet air temp, oil temp, crank position, TPS & ICV as standard. NO MAP or MAF sensors. I can also get the standard maps from the existing ECU. It also has 2 coils each driving 2 plugs per head
At the moment I'm looking to see if I can avoid the Sword of Damocles hanging over the bike by switching to an aftermarket ECU
So my question is can Mega/Microsquirt be used with these existing sensors and initially can the existing fuel/ignition maps be translated across to the MS
At the moment I'm only looking for general confirmation that I setting out on a journey that will be successful in the end, but if the MS is a realistic solution, I plan to do a LOT of reading and (my apologies to you all now) a LOT of questioning on the forum
Cheers and thanks in advance

Check > Quick links: Manuals and look at the microsquirt sounds ideal for your Guzzi !!
You cant swap the oem settings to the microsquirt.
But all not known sensors can be calibrated.
Try to figure out witch sensors you have.
Try to find out the crank or cam teeth pattern.
Ecu needs this to know crank angle/position.

Re: Potential New User and Greetings
Focus on that crank wheel config first. That seems to be a problem for many bike installs; and you probably don't have the space to add a simple missing-tooth wheel if the stock wheel isn't supported in the FW. Also, let's hope somebody will soon confirm that the odd-fire 90* V-twin is supported.
As said above, sensors/coils/injectors are rarely a big problem; not much worry there.

Here's a picture of the crank wheel (Guzzi call it a Phonic Wheel)
If I count the visible teeth I get 46 and eyeballing the gap I guess 2 missing.
Would that make it a 48-2 wheel?
In my reading so far I don't think I've seen reference to wheels with 2 missing teeth
If its not 48-2 then it has to be a 47-1 which would be even weirder given that 47 is a prime number!!

Re: Potential New User and Greetings
Yes, that looks like a 48-2 wheel. I've seen this arrangement on a lot of Italian bikes. Does it spin at cam or crank speed?

Trish,
It would be nice to infect you whit the megasquirt virus
But the only problem you seem to have is the baro sensor.
Is it possible to relocate this or an other baro sensor ?
Most Italian bike factories are to small to make there own sensors, they use car parts.
I run a Ducati ST2 engine in a Cagiva Elefant, its also full of magneti marrelli sensors.
And it has a 48-2 camwheel (46teeth and 2 teeth left out) 48 minus 2.
My baro/airbox sensor is the same as on some fiat cars.
Makes a lot difference moneywise if you order a Fiat or Ducati sensor, yes I am Dutch
And this serie of ECU's is also used Guzzi's and MV Agusta, makes you think doesn't it ?

It runs at cam speed - I thought it was on the Crank - I told you I was on a learning/discovery curve!
Its looked at by a Magneti Marelli SEN813 sensor if that is of relevance
Lav
The Baro sensor in the current set up is the biggest issue in that its signal is taken to the ECU by CAN BUS
SO while I might be able to get the immobiliser eliminated from the ECU the baro sensor would be a problem ...... hence the MS investigations

Re: Potential New User and Greetings
There is probably more running on can bus, not only the baro sensor.Tris1948 wrote: Lav

ABS somehow connected to canbus ?
Do you need the OEM ecu to run ABS and or canbus ?
Re: Potential New User and Greetings
Old school this bike - no ABS
I'll have a look at the wiring diagram but I think everything else engine wise goes straight to the ECU
