Can anyone please advise if any of the ECUs fitted to the later Fiat Pandas were of the self learning type ? These are Magneti Marelli IAW 6FSH and 6FSK.
I had always been under the impression that later cars, such as the Cinquecento and possibly the Mk1 Puntos had self learning types but that the Pandas did not.
If anyone can offer definative confirmation on this question, it would be much appreciated.
Thank you, Pete. petel@clara.co.uk

Pete - not a clue myself but the guys on the bba-reman forum might know......only maybe!
www.bba-reman.com look for the forum

Thanks for your input DL. I put the question on the forum, it has been there for seven days, has been read 69 times and zero response.
Back to the drawing board.

What exactly do you want the Ecu to self-learn,your question is a little unclear?Most modern engine management control units have adaptive learning facilty ,which means that if an engine elect part is replaced or the battery is disconnected the car has to be driven for at least 5-10 miles to relearn drive cycle.Some of the Marelli/fiat ecus need to be revved above 5000 rpm at least 3 times to relearn part of the adaptation.

Thank you for your reply. As stated in my original post, I seek to establish if the two ECUs noted have the ability to self learn as you describe or if they are of fixed values.
Any confirmation on this question would be much appreciated.
Thank you, Pete.

I know that on my old Mondeo I found out about the self learning process from reading the Haynes manual. Presumably (?) if no such procedure is given in the manual for the panda (assuming this manual exists) then the ECU does not need to be taught? Or no special procedures are needed to re-train it at least.

Hello Kev.
Thanks for your reply. There are two Haynes manuals for the Panda, I have both and can find no mention of self learning ECUs. It should be noted that these manuals do not cover the SPI versions well, as they ( the SPI versions ) arrived relatively late in the importation into UK.
The Porter manual states that the ECUs are self learning but gives no further detail.
This is why I am seeking definative confirmation on this question.
Rgds, Pete.

I don`t know but if it helps.self learning ecu`s remember the state of all sensors at last run so if a problem occurs with a sensor it forgets the fact that sensor has gone wrong and carries on with the settings it was programed with.which all ecu`s do the only exception is that some can tell you by fault code what is wrong.some need to be connected to a diagnostics computer to tell you what is wrong this is just a guideline

Hello Mech 1
Thanks for your reply. I may be mistaken but I think you will find that what you describe is the "Limp home value" rather than a self learning process.
Example, on the Bosch Monojetronic system fitted on the earlier SPI Pandas/Unos/Tipos etc,which were not self learning, the ECU holds in reserve a fixed value for five sensors under its control. If a sensor fails, the ECU gets an out-of-limits reading from that sensor and on recognizing this, subsitutes the fixed value from its memory and allows the car to be driven at reduced efficiency, hence the term "Limp home value" The owner may not even notice this and may be unaware of any problem.
Thanks again, Pete.

UPDATE. Have just been advised of an Italian technical website, which states that the Bosch Monojetronic systems ECU "IS" of the self learning type. Have looked at the site but cannot confirm because it is all in Italian.
Can anyone please offer any confirmation on this?
Thank you, Pete.

Does`nt microsoft do a conversion software program to translate.and am puzzled why you need to know?

Goto babelfish.altavista.com . Select "Italian to English" and then copy/paste the italian text into the translation box.

Or do as above but instead of pasting the text, enter the URL in the handy box provided and it will (badly) translate the page for you, leaving in Italian any words it doesn't know. You'd be much better getting an Italian friend to help out tho (anyone on here fluent enough?) as babelfish is a direct word for word translator and you get no idea of context etc.

I'd agreed about the badly:

Injection electronic digita them without the ignition, the mounted system of injection e' on the farfallato body and incorporates the pressure regolator benzine, the current to the candles comes sended with the aid of one telephone exchange separate ignition. The telephone exchange calculates the weight of the inhaled air finding of the temperature and the angle of opening butterfly correcting the mixture title it with the reading of the factor lambda. The probe lambda e' mounted even if the fed car e' to red benzine. The telephone exchange incorporates a car-learning system in order to adapt the injection to the usuries that take part in the motor, to every operation of maintenance or advisable repair e' to rifare the learning procedure in order to improve the yield of the motor. The verifications on the system have been carried out with the telephone exchange connected to the system (but various indication) in order to verify in this way make contacts or the defects which had to the wiring, allowing to carry out one reliable diagnosis più'.

The issue is also the technical words that ordinary translation freaks out on.

Hello Another John H
Thanks for the reply. Good for a laugh if nothing else, especially the bit about the "Telephone exchange".
The file runs to twenty pages, of which the first eight refer to the Monojetronic system. I am not about to try to translate them all.
The text does however, make reference to a "Car-learning system" which is what I am interested in. I have asked the Italian chap if he would indicate which section of the file, refers to the re-setting of the ECU and will post again if he responds.
Thanks again, Pete.

Hello to all.
The Italian chap has been back to me and indicated the section of the file with the self learning details. I have translated this and find it to be correct.
This means that ( unless the information on the file is wrong and contrary to what I have been told by ECU doctors and Fiat dealership mechanics ) it seems that the Bosch Monojetronic systems ECU does have a self learning function.
This now brings me back to the original question,
Can anyone please offer definative confirmation of a self learning function on the Magneti Marelli ECUs, IAW 6FSH and 6FSK?
Thank you, Pete.
