Megasquirt noob here. I replaced my outdated FJO on my 4AGE-powered AE86 with a MS3Pro. I recently finished rewiring the car, along with updating the ignition.
I am in the configuration and setup stages of my project, which is exciting! I am using Tuner Studio to enter in the details as it came with the ECU and seems to be commonly used for Megasquirt. Much of the basic settings and configurations are straightforward enough, but I am struggling with designating things like idle control, fan control, and extra sensors. I know how I wired the car, and my frame of reference is the MS3Pro harness (and corresponding manual) which has handy printed labels on the wires. The drop down menus in Tuner Studio seem to reference pins/circuits on the MS board (things like FIDLE, IDLE, pin D15, etc) These designations are all Greek to me as the MS3Pro circuit are assigned and the pinout and included wiring harness is labelled with things like Idle Out 1, Digital Switched In 3, PWM Out 2, Stepper IAC Out 1B, etc. The MS3Pro manual walks you through setup but doesn't specify more detail than, "use this menu, assign inputs/outputs as needed."
How does someone who didn't solder up their own board go about making sense of the disparity? Is there some magical translation key I am missing? Should I split open the case on the ECU and trace everything? Should I use another program other than Tuner Studio? Are there different Tuner Studio versions for MS3Pro vs MS2/MS3?
