Controlling the Instrument Cluster's Display

A little project I'm working on. :) (Sorry for the horrid picture!)

Here's the elevator pitch: Directly control the LCD panel with a microcontroller to display custom information on the instrument cluster. The microcontroller will also read the data that would normally be going to the LCD and can choose to display that info or custom info.

Maybe you want to display OBDII parameters where the MPG is. Maybe you want to change the charge, assist, and SOC gauges to accurately reflect amps in/out, real battery SOC, etc.

I've got a few other ideas as well. Once I'm finished with this project I'll open-source everything I've learned and perhaps produce some PCBs to sell. We'll see!

I have work and other projects as well, so it may be slow going at times. But I'll try to give updates fairly regularly.
I don't think this has ever been done before. I hope you guys are excited!
If anybody is or wants to work on something similar, I'll be glad to share what I know; just ask.

Hello everyone, greetings and happy new year from Canada!

I just stumbled across this thread and I am truly amazed! Such awesome work and I can't wait to see it come to fruition.

Thank you so much to everyone that linked the service manual PDFs and wiring diagrams, I have been struggling to find those.

I have an automatic 2000 Honda Civic (OBDIIb) and I am looking to swap my boring OEM Civic cluster for the ZE1 Insight cluster. Originally I just wanted to find the wiring diagrams so I can wire some basic functions to work like the rpm and km/h but now I am wondering if I can somehow retrofit the Pegasus module with an Insight cluster into my Civic. I know its kind of an odd project but any advice or insight would be appreciated. heh.

Thanks in advance!!! :)
