MSD6AL and Ready to run distributor question
Posted: Mon Nov 07, 2011 7:16 pm
I am switching over from fuel only to control the spark. I have a MSD 6AL box and a ready to run distributor. I have the distributor locked for no advance and vacuum removed. I am trying to determine what mods I have to make to my MS2 running the latest code. I do not use the Extra code. I have pin 24 on the ms2 hooked to the orange wire from the distributor. I have pin 36 hooked up to the white wire going to the msd box. I am not using the HEI module between the distributor and the relay box because I read I do not need it. Here are my settings for Tuner studio:
trigger offset 6 degrees
ignition input capture falling edge
cranking trigger trigger rise
coil charge scheme standard coil charge
spark output going high (inverted)
max dwell duration 25.5
max spark duration 25.5

My question is, what modifications do I have to do to my MS2? I have two computers I could use, one has Input: VR sensor and Output: High current direct coil drive,
and the other has Input: Hall and Output: high current ignition driver circuit
I read on a similar post that I would need to use the Hall input, (treat it as a points distributor setup).
Here is the post where Matt says “To use a ready to run distributor, you need to create a 12 volt pull up on the input by connecting pin 24 to a 12 volt source through a 1K resistor.”

Is there a diagram for the input circuit mod I can find somewhere?
Also, Do I have to modify my Output circuit with the IGBT Pull up circuit shown on step 65 of the assembly manual? From the manual: Soldering a 1K Ohm resistor to the hole marked S12 immediately below R57 (this gives a 12 Volt pull-up)
Thanks,
Rob
