pfederighi · 05-18-2010, 03:16 PM

Hello.

I have a 1991 Metro with a vacuum advance distributor. I also have a junker 1992 Metro with an electronic advance distributor. Based on the assumption the elctronic control is better than the vacuum control, I would like to use the 1992 distributor. After looking at the wiring diagrams, it appears that I would have to swap out the ECU if I were to use the electronic distributor in the 1991 Metro.

Is this correct?

Are there any issues with swapping a 1992 ECU with a 1991 car? Will I have to swap any other components in order to make the ECU happy? Will I have to move wires around on the multiwire connectors?

Thanks.
- Peter
