Timing...not sure where its coming from

[Scott125]

I'm messing with an 02 Camaro, 6 speed.

We were dynoing it and intermittently, around 3200-4000rpm, the timing will jump to 34*. I logged all the various adder tables and none of them are adding it. For the hell of it, I dropped the main spark table down several degrees...from 27 to 21 and it still goes to 34.

Any insight...thoughts?

Thanks

take a look at ur airflow values.. if it's not sucking in enough air, your gonna run off timing based on ur cruise area tables.

Does it fall out of PE when it happens? Does the TB have a bumpstop mod or is it aftermarket?
