71 Duster 360 turbo build

Troubleshooting the crank sensor failure became its own ordeal as I allowed other “issues” to distract me. Although I was fairly certain the sensor had died, I wanted to be sure before replacing it. Composite logs did show some, erratic, readings so I messed with the gap without success. I removed the sensor and watched the tooth log while moving a piece of steel beneath it. Microsquirt picked up the reading and even kicked on the fuel pump. Sensor okay? I then noticed that offline changes I made to the tune did not trigger the initial “settings changed” prompt when connecting to the car. Thinking the firmware could have an issue, I checked for updates, found new firmware, and updated…without reading or following directions….New problem unlocked! The firmware no longer matched any of my tunes, and I spent hours over the next day attempting to import my old tune settings. Tried the old sensor. No luck. New sensor; fired up. It’s back up and running “okay,” but there are plenty of small issues to deal with. Autotune has stopped correcting my tables, time based accel enrichment is wayyy off, and PWM to my fan is only giving me about 50% fan speed so it’s getting hot. The car may be close enough to go ahead and start the MS3 project, but I would prefer to have all these issues resolved before I potentially create more.
