Trigger Angle Offset Q
 
I thought the dyno operator had gone through the trigger wizard, but apparently he did not. The tune I had been driving around with was set to 10*, and after completing the calibration, the offset is now set to 6*. The yeloow and white marks line up with 10 and tdc, respectively.

When I turned back on the timing table, the car appears to be idling advanced of where it had been.

Could someone confirm that the motor is running with more advance with a 6* offset vs a 10*? Or do I have less timing? (Is offset CW or CCW?)

Why not put it back to 10 degrees, hit it with your timing light and know for sure what the effect is?

If he tuned it while the base timing was at 6° then when you adjust it to 10° all the timing will be 4° more advanced than it was when it was tuned.

I'm pretty sure you are now 4* less advanced than when he tuned it.
