Advancing Ignition Timing

Is there any way to advance the ignition timing on the Renix motors?

the timing is computer controlled.
So you haveto get the ECU to do it. That said, go and find the "high altitude" CPS, it's supposed to advance the ignition timing a few degrees.
Why do you want to advance the timing?

Using a "high altitude cps" did cross my mind until I found a picture of one. The sensor is simply repositioned on the bracket. I also thought about slotting or elongating the mounting holes to allow for adjustment. As far as why?..well just looking to squeeze some more ponies out I suppose.
