8* timing offset built NB
I'm slowly getting my built VVT motor up & running. I have gone through the trigger wizard routine, and I was advanced by 18* when trying to hit fixed time of 10*. This is with VVT disconnected to eliminate it as a variable. A little searching says this is outside of the norm for a NB setup (4-6*). the motor is a '96 block and pulley, new NB timing wheel, NB crank sensor mounted to a boundary stage 2 pump. I found Rev's comment on the matter:
Any experience here? I'm basically ready to go romp on it & seat the rings, but I don't want to proceed if 8* timing correction is indicative of some other issue.
Trigger angle should be in the 4-6 area for stock NBs.
By stock, I mean stock trigger-wise, mainly the crank wheel and sensor.
If you have the stock parts in the stock location, and you require a value outside the 4-6 window, either your timing light is off or you can't read the timing off the wheel (have someone else do it for you) or you have an engine issue.
I've never, EVER, seen an NB require something outside the 4-6 window.

I set tunerstudio to fixed timing with a value of 10* advanced. Timing light indicated a value of 18* advanced. I had to add +8* to the trigger wizard tool to get the timing adjusted to 10* advanced. Now with a +8 in the trigger wizard menu, I have 10* advanced timing, right where it should be.
