MSD DIGITAL 7 7530 T
 

Hello All
I have a dragster with the digital 7.. i hooked up my computer and do not see where i can program it to activate my electric shifter.. Also .. is see most of the outputs can only handle 3amps.
So where do i program the MSD to shift 1 time at a certain RPM.??


Thanks In Advance

I have the same box, but I use the MSD monitor mounted in my truck. Here is the link to MSD so you can go to it and download the instruction sheet.

If you look on the list there is one that says timer switch, rpm switch. Choose which one you want it'll turn off the other one - sounds like the rpm switch, and set that for the revs you want.

I set mine to work off the yellow wire which is the shift light in the settings. You can feed the yellow wire to a relay then out to the shifter. The MSD box sends out a ground and the relay comverts it to positive.

Hope this helps...
