Motronic 1.1 Or 1.3? (e30)

Recommended Posts

Hi,

I've recently brought a 1989 302i Touring, which I'm enjoying.

I was hoping someone could tell me which version of Motronic is fitted to this model.

Also... I understand this model has a M20 powerplant, is the 2 litre a smaller bore or stroke?

Thanks in advance.

Correction 1989 = facelift.

preface lift did not come motronic.

Facelift 320i's only came out with motronic 1.3. This was already mentioned above though!

Check to see if it has a wheel with small teeth ( if i remember correctly ) on it running on the front of the crank with a sensor mounted to the block which reads off the teeth. If it does, its 1.3, if not, its 1.1.

Or just find out the number on the ECU and google it. Or unplug the ECU and see how many rows of connectors the plug is, if its 3 rows it is Motronic 1.3.

I'd assume it's 1.1 though.

preF/L 320i is Ljet.

All F/L 320i and 325i are motronic 1.3
