timing ignition

[TopVpowerRoadste]

Hi everyone,

I need to adjust the timing ignition of my 1990 S2 2.9i.
Steve Heath's bible says 8° for the timing. What do you think?
Do I need to disconnect the ECU?

Many thanks for your help.

Hi everyone,

Once again thank you to all of you for your intervetion.

Lewdon, as you said, the ECU tries to fiddle with the timing while you are setting it, and stops you being very accurate.
I'll try your suggestion with the blue/red wire.

I'll keep you posted.
