Timing Is Not Advancing

[ReefBlueHatch]

A few months ago I bumped my timing up to 14 degress w/ 93 octane and I didn't see a difference. So I got to thinking and I checked to see if the timing would advance with higher RPMs - it did not. The previous owner put in a MSD box and coil. Any ideas why my timing is not advancing?

Thanks for any help!

Is the SPOUT connector installed?

Yes it is.

Faulty ECM or spout connector.

If you're checking it with the ignition-box connected, the multiple sparks might be screwing with your timing light. Bypass the box and see what gives.
