Have a 302 with a SI, carb'd with vic jr heads. I called msd for setup advice on the box. They were less then helpful. Having never owned a programmable box is there anything I should setup first before initial fireup?? As far as i know i fire it up and set my advance with the timing light and it should function with a set degree of advance via my locked out distributor? I have done very litlle research on it and I'm not 100% sure what to set the timing at? 91 octane pump gas here.
