Message: [QUOTE="Chvyrkr, post: 191767, member: 169"] My PMR engine ran a 1.0 for close to 30k, no issues there. I was always under the impression that nobody really knew exactly what the blue CPS did, advance, retard, etc. To further clarify, when we tuned my 02 at Beans it got strapped to a dyno. Jonathan added a degree or so at a time until power leveled off, and pulled the timing back to peak power. He asked me if I wanted it backed off any further, but since the approx timing value was only 1 or 2 degree's past stock, I opted to leave it. Now, if I swapped CPS's, and thought my timing was off, I could take the truck back down, and readdress the timing curve. And the effective timing, when tuned that way, would be the same after both the first and second events. Goes bang at the same time. [/QUOTE]
