Hi everyone,

I'm currently developping an emulator for Alfa Tester to be used on 33s fitted with Marelli Fuel System.
I was wondering if any of you has already used either the FLT/Alfa Tester/Examiner on these 33s and could tell me exactly what functions are available in the factory diag computer.
I suspect there is a way of clearing faults in memory via the diag plug, also adjusting a few parameters but today i'm stuck with readings only.

Besides, if any of you got any info on the protocol used in bosch systems fitted to Alfa 33 (most helpful would be Motronic ML4.1) i'd be grateful.

With best regards,
zp

Have you seen 6th icon from left on the top frame of http://www.alfa-pages.co.uk/

Direct link to it is http://www.alfa-pages.co.uk/injectin.htm, but I like those icons on top because Keith has put there valuable information not only on injection.

Regards Tino

hi,

yes, i've been there all right.
the page on IAW says : " Nothing here yet "
besides, the info i'm looking for doesn't appear on the workshop manual, which I have (thanks Keith) ; i'm looking for someone who used or uses the Alfa Tester, of has access to it, or has insider information about the intrinsics of the diag protocol. Sorry, not an easy one, but hopefully it will end up with a nice hand-held tester? hoping to hear from you,

best regards,
zp

Sorry, but in that case there is nothing I can help you with.
3-4 years ago I tried to find here in Croatia Alfa tester, and at that time AR dealers told me that they had upgraded their testing PCs with new software which excludes all 33s Sad

There was nobody that had any knowladge about 33 AR tester.

I wish you good luck with project.

Hi,

Thanks for the info, unfortunately i had gone on holiday and missed the auction.
Besides, my first prototype is now fairly advanced and i hope it to be functional at the end of the month.
Have been hacking the ML4.1 too, but still a long way to go.

Best regards,
zp

Hi!

Got my first prototype working...using a nice blue LCD display!
The little EPM8 from ZPower, inc. can display :
-engine rpm
-water temp
-intake air temp
-batt voltage
-injection duration
-ignition advance
-manifold absolute pressure
-throttle angle
-lambda value
-idle control parameters
-diagnostic trouble codes

Got to clean my room now!

Best regards,
zp

That's AMAZING!!!!

Anyone know if there's something which can go on the LE3 Jetronic system like this?????

yope but will need time and a spare ECU...
will work on it as soon as the ML4.1 model is finished.

ZP,

You seem very keen? Gonna start 'mass manufacturing' them????

Very Happy

ZP,

I can supply you a Jetronic LE 3.2 ECU I have for spare. Let me know if you are interested.

hi,

yes i intend to "mass manufacture", made a custom designed PCB and sourced connectors.
soon i'll have a nice kit ready with full installation instructions.
currently only Marelli 8F.86 fitted 1.3ie Alfa 33 is supported but ML4.1 version (1.7 16V) will follow as soon as i'm done cracking the box (having trouble figuring a few things out at the moment)
I will go on with MP3.1 ECU.
besides, as far as i can recall Jetronic ECUs don't support diagnostic (no diag socket on the car) ; adding an ECU monitor would still be possible but would require to carry out extensive modification to the ECU internal circuitry. I doubt "mass production" would be possible.

best regards,

Hi...

I would like to say something, but the only word that cames to my mouth
is:
- UAU!!!!!!! Surprised

Very nice work, looks very neat. When you manage to "crack" the ML 4.1
tell ous something. Very Happy

I would be very interested, in buying you one of those... Very Happy

Congratulations

P.Camilo

Same here, would love one of those toys for the P4!!

Well done mate! Smile

Hi,

currently finishing the marelli unit and will soon move to the P4 project...but as i'm currently moving all my electronics stuff will soon be held prisoner in a cardboard box and my developments will undergo a big freeze...
will keep you informed as soon as it works!

Hi,

The 16V box is currently undergoing a serious cracking...
My prototype board is ready now, let's have some fun!

Some results soon (I hope!)

Hi

Looks good...

Were do you connect it to the ECU??
Do you use the terminal, for the "Alfa Tester"???

You diagnostic tool will give the error codes, or it will translate them directly??

all the best
P.Camilo

Hi,

yes of course i'm interfacing with the diagnostic socket for the alfa tester.

more images of my interface for Marelli ECU here :
http://alfaimola.free.fr/technique/injection/epm8/index.html

I will translate fault codes in human-readable language...todays LCD screens are easily available and don't cost much...i'm through with 7-segment displays....

with best regards,
zp

Hi Guys, cracking topic.... and some great work!

Does anyone know what this connector is for on the LE3 Jetronic? Can it be used to get similar info out of this ECU??? :

Cheerz,

Bob

Hiya Gritsop,

I vaguely remember that. But that only uses one of the pins on the connector? CAN the others be used to gain diagnostic information?

hi,

what's this post doing on my diag thread?
i'd sure like to see such a displeasant member banned out of the forum.
