Default Holley CAN I/O module

I know a lot of you guys use the Terminator X, so this might be useful...

Oh yes, I’m so excited they released this. My only gripe about the Terminator x on my turbo truck. This may be the last day for the haltech on my other car.

Pretty sure it’s a micro squirt in a different case lol. I’ve got 2 in the mail along with another Terminator X for my other car.

What's the gain for LS guys? Don't even remember when I updated mine. Every time I've looked at the update summary its all been for Mopar/Ford and LT crap so I haven't bothered.

In order to use the I/O expander, there is a firmware update required. For Dominator and HP ECUs, v6 build 200 added the I/O expander functionality. The TerminatorX v2 update should be out soon.

prretty sure this is the mcu: https://www.microchip.com/wwwproducts/en/ATSAMC21J18A

if the outputs had more current rating this would be a sweet rear bcm to eliminate having to run a bunch of wires front to back in the car. i might look around for some leds and stuff maybe i can use it for that anyway. my next project i want to have zero mechanical relays.

i wish they would redo the smartwire firmware to make it into a holley product. i have one and it needs a $400 box to talk to a holley and you still can only send limited data one way.
