Can someone please explain/post a link how to set the base ignition timing on 05 EVO VIII? I have searched and searched and really couldn't find a write-up on it. Such a simple thing but it's not very self explanatory. I've done multiple DSM's back in the day but this isn't the same.

I understand using EvoScan to set the ECU to accept a change. But I don't see any marks on any of the pulleys and I don't know where to advance/retard once I find my mark.

Thank you much.

Steve
