Digital Dash Upgrade - Was it Worth It?

Thanks to The Zebra for sponsoring today’s video. Click to learn everything you ever wanted to know about car insurance.

Thank you to Optimist Studios​ for letting us shoot this wicked fun Zebra Ad in their lot! Check em out!

Thank you to our good friends at EAD Exotics- for helping us get out hands on cool cars to do fun stuff with!

Thanks to DDE-EFI for all the help on the dash!

So we opted to go the fancy route and swap our Miata gauge cluster for a supercar-like digital dash! Now the problem is that we can’t read fuel levels or oil pressure! So today we fixed those problems by adding some aftermarket bits to our ECU!

Money Pit is where you get to learn about cars as we work on them. Each ep we’ll breakdown how each component works and then we’ll upgrade it. Join us in our journey to build cool cars, learn about them, and drive the crap out of them!

Some of our best videos ever are coming out soon, stay tuned so you won't miss a thing!

    For the display, I think the refresh rate should be increased to at least 60 Hz (my preference would be at least 100 Hz). Also, I much prefer traditional speedometers to GPS-based speedometers. Lower latency, and no need to worry about signal coverage.

    Any competent 12V tech will tell you those "Vampire clamps /quick splice connectors" are CRAP. The first bump you hit, or moisture/humidity, all bets are off. You want a foolproof install, solder, dilectric grease and tape, period! I've redone too many aftermarket alarm/remote starter installs with those crappy connectors to count.

    The lag issue on the screen is because the CPU is way too slow. In other words, the raspberry pi isn't good enough for that job.

    zack you need to close tuner studio on the dash and set the baud rate to 115200 on whatever usb port the megasquirt is hooked up to. you can just search how to do it on google. its a raspberry pi so it should be easy, i have basically the same setup in my car and the dash runs super smooth with the higher baud rate. please do it so the comments about the slow refresh rate of the screen will stop.

    I seriously think a Raspberry Pi 4 would make the refresh even better. Judging by the performance of that Rasbian based Linux environment, that looks like a Raspberry Pi Zero. I really think part of that lag, is system lag. Even navigating menus looks sluggish.
