Just wondering what kinf of effect this would/could have...
I imagine if you lie about initial advance in dis. the it would throw off inj. timing correct?
I am sure also that running larger injectors w short PW at lower RPM or when over injected this could help..

Grumpy, I would be sure you have done this?

 

IMO, it probably will only help at slow engine speeds, since as the RPM/Load goes up the PW quickly *overlaps* the cam events. That said, it's at the lower RPMs, when you first start loading the converter.

On the SEFI, ie, GNs, there's been a none ending discussion about altering the Cam Synch signal and having an effect on engine performance.

I had a code change for playing with it, but I was just getting to that when it turned cold and haven't gotten to do any testing with it.
