[alfa] More Motronic secrets!

["John Fielding" <johnf@xxxxxxxxxxxxxxx>]

Mr. Bosch will probably get a bit upset by this disclosure, but here goes.  It is covered
in their service manual for the Alfa Romeo Alfetta/Spider using the early Motronic ECU.
This would be circa 1984 for Euro cars and about 1985 onwards for NA vehicles.

For those of you running the Motronic you might care to take a look inside the ECU harness
connector to see if pin # 10 and pin # 5 are connected together.  In the Swiss version the
two pins are linked.  This retards the ignition timing to meet their emissions
specification.  The removal of the link allows more ignition advance across the rpm range.

To open the harness connector, remove the nylon tie-strap where the harness enters the
connector and slide back the pvc sheath.
Remove the small self-tapping screw holding the outer shell in place.  Slide the
shell off until the back of the connector is exposed.

Any American owners who take a peek, please let me know what you find!

Also, any one who can supply the Bosch part number for the ECU fitted to the American
Spider?  It should a number similar to 0261-200-xxx format and on a sticker on the outside
of the ECU box..
