I have an 85 Euro 16V that has a numbered dial (numbered from 1 to 7) near the battery. I think it is used to retard the timing. I have the CD rom for my car but I cannot find this numbered dial anywhere and hence, cannot adjust it properly.
Can anyone help me to identify this and what number it should be set on? Thanks

You are correct. I think it is used on the euro market so the engine can run OK on different fuels.

Doc???

1000% correct! Timing correction for POOR quality fuels! Euro 16V engines had 10.5/1 compression & NO knock sensors.

Thanks guys - OK, so if i am running 94 octane Sunoco gas, where sould the dial be set? i.e - at what setting will I get the most power from the car without sacrificing too much fuel or too much over heating?
