if you want to run fixed timing, the module u use i think is off a falcon... its a bosch item "BIM024" is the part number, has 4 pinouts
2 of them go to earth and power and the other 2 get plugged into the standard 4age dissy, i had a pic of this somewhere that blair sent me as i originally did the setup on his car, i think he pmd me the pics, i shall have a look for them
