'70 Dart 392 Project; what direction?

Well damn I’m close!
Lot done today. Short of connecting the laptop and confirming sensors and calibrating O2 sensors I believe im done with the megasquirt wiring. Also got my AC and coolant lines connected and clamped under the dash, got the first two vent hoses ran to the defrost vents and tied up a ton of wiring. Got all my relays wired and grounds ran. Still waiting on a lower radiator hose reducing coupler to show up so I can fill coolant, then I need to fill trans/rear diff, power steering, coolant. And run through the initial setup on megasquirt. Hope to crank it Monday (open headers of course).

Fabbed up a redneck gauge holder on the dash for now. Not permanent but had to go somewhere with the O2 gauge.


It’s exciting just to see the AFR gauge go live and hear the fuel pump do its initial 2 second prime when the key goes to ON. :)

Happy 4th everyone.

I ran mine a bit with open headers but could do any tuning. The O2 was too close to the end of the pipe and would read super lean when it was actually very fat!
I’d recommend going through all the injector and coil tests just to make sure you don’t have any wiring errors. It doesn’t take long to go through the firing order for each of them.
