Stock AXCA chip
« on: July 18 2012, 01:26:51 PM »
I don't see why the stock chip on a stock car get such a bad knock, I suspect things get exaggerated over time?

Once the rod gets shortened and boost cranked  I will believe it has no/little margin.
But if you have a scan tool and see no knock with whatever octane you have available it it so bad?

Flame away :)

Without writing a novel the stock chip has 22-23 degs of timing.   This was designed for 12-14lbs of boost with better pump gas circ. 1987.   If you lower your boost below this I guess you can still use it without knock.

A lot of broken parts does not make you a racer; it makes you a slow learner.
