MS3 not connecting to Tuner Studio
 

Hey everyone, I'm having some issues getting Tuner Studio to connect to my MS3 pnp on my 2001 Miata. Non-turbo, lots of bolt-ons. I think 1.4 is the firmware?

The software isn't recognizing the ECU, and I hear a constant clicking noise from an engine relay when the key is on to power.

I installed an AEM wideband and GM IAT at the same time as the Megasquirt. The AEM was first wired to the DB37 harness, then moved to the stock o2 wire harness. Since my MS3 has a USB-B (printer cable) port, I'm using that instead of the serial port.

So is this a cable issue? Is there something big I'm missing? Someone suggested me to check the fuses, which I haven't done. I'll be away from my car until this Sat.

The clicking needs to be figured out, sounds like a relay issue, possibly the main relay?
