My engine: Stock 2003 6.0 Chevrolet LQ4, 60,000 miles, running all stock injectors, coils, plug connecters, et cetra.
Board: MS3 3.0 with MS3X
Mission: sequential fuel, timing, and spark
I have read through all of the manual and its associated pages. Up until now, all directions have been self-explanatory. However, I require help on steps 27 and 28, which involve the board setup for trigger and spark. What is the best way to discern which tach input I should go with? From the best I can understand, VR input is the correct choice, but I don't understand what pullup is, or if it is required for my application.
After that, I assume, I need to set for high output. I see the required steps for single high current, but should I go with multiple.
Thank you in advance.
