i am running a digital 7 box,msd crank trigger and msd crank trigger dist. When i set up the system do you set the total timing at 32 degrees like what i want to run on the crank so do you set one of the magenets with timing pointer on 32 then the pickup on and the magnet on the trigger at 32 and does the dist. set up so the rotor is on number one at the same time?Or do you set up the rotor on the dist. to tdc then the mag. on the crank trigger to fire at the 32 degrees the crank is rotated to?The paper work msd sent is a little confusing and i just wanted to make sure i got this right.Thanks Jeff

Set-up for a Crank Trigger:

The following timing values are used for example, place your actual timing values in place of the examples.

1.)Install the Crank Trigger Wheel onto the Balancer. Rotate the Engine to # 1 Compression Stroke, 32 Degrees on the Balancer.
2.)Line up the Crank Trigger Sensor to one of the Magnets on the Crank Trigger Wheel.
3.)Once the above is set, be sure you are working with a Distributor that has been locked out (no Mechanical or Vacuum Advance). Install the Distributor with the rotor facing # 1 Cap Pole.
4.)You will need to drill a Hole (5/16 or 3/8 ), in the Cap just behind the # 1 Cap Pole, connect a Timing Light to # 1 Plug wire and start the Engine. Check the timing to make sure you have 32 degrees on the Balancer, if it isn't 32 degrees adjust the Crank Trigger accordingly.
Then check the Rotor Phase by pointing the Timing Light through the Hole in the top of the Distributor Cap (that you drilled earlier). By rotating the Distributor, you can align the Rotor directly on # 1 Cylinder.

A word of caution when phasing the Rotor with Nitrous and Boost applications:
With Nitrous and Boost applications you will have to retard the timing to the most retarded value you will be using to phase the rotor. For example: If you’re running a static timing setting of 32 degrees and are pulling 12 degrees out for Nitrous or Boost, leaving you with a total of 20 degrees. You need to phase the rotor at 20 degrees of timing.

I hope this helps,
