Hey guys i am getting ready to swap my 92 fox body over to the EFI Source Microsquirt. Do I need to run some sort of igniton box with the TFI or can I run just off the TFI. I am running an MSD distributor with a motorcraft TFI module installed.

Nope, tfi fires the coil. You can bypass the tfi and have the micro fire an ignition box if you want ecu controlled 2step and spark cut rev limiter

Ok cool. Am I correct in thinking that if I just run of the TFI i will still have a rev limiter in the Micro. It will just cut fuel not spark?
