So let me get this right? I can install my cam "straight up".Then get some type of after market hook up like autoprom, promulator, or some other laptop hook up that can advance or retard timing so the engine can be tuned. Tuned as in for nitrous and all that stuff. Thank you all in advance or retard .

 

Yep.

 

Camshaft timing has nothing to do with prom tuning. You can set the cam timing 5* advance and still run the stock IGNITION timing(or anything you want). Cam timing is not ignition timing... Just want to clear that up. That is what you m eant?

 

Well lets just say my cam likes to be installed -6* to make best power. Thats not the same as just pulling out -6* via computer, because computer timing is through out the whole engine curve.
Right?

 

Cam timing is done mechanically via the timing chain, sprockets, offset bushings or multiple keyways.

The ECM timing is the ignition spark advance timing.

Can't change the cam timing via the ECM, only the ignition timing.
