Re: msd programmable ignition 7530T
It's a powerful tool. Not a curve - straight line ramp. So if you have a car with 40 degrees timing and remove 10 degrees for 1 second your result is:
30* at launch
31* .1 after launch
32* .2 after launch
33* .3
and so on till 1 second out you are back to the 40.
Regarding how much, I suggest starting with 6 degrees for for you 60' time. Then you correlate results with your data logger shaft & g-meter to tune from there.
Give me a call if you need more info.
