The lockup converter should still work, but i am not positive. I have a lockup kit on my 200-4R but i eliminated my ECM. I am running a complete TV cable kit from Bowtie Overdrives. At the time i put my 200-4R in the simple brackets from jegs were not available so i spent $200on the complete kit to make my TV work with my Holley carb.
