Reading datastreams from GM OBD-1 with a Raspberry Pi 

Old video but still very helpful. I have an ODB1 GM and I want to get rid of my analog gauge cluster for something like this. I'd imagine there are even better scripts out there now 7 years later so this will be fantastic. Thank you sir.

Beautiful truck with beautiful paint job

Very very nice!! Congrats! I was looking around for some ideas, I'm looking for doing something like that on my old Honda Accord '94.

I've been looking for the data breakdown from the serial line. I want to connect my arduino (since it doesn't require an OS and boots in about a second) to use for radiator fan control with a DC motor controller and peripheral monitoring, etc- whatever the ECM actually outputs. Just not sure where to find them. I guess I can start with the USB cable and just watch it in Putty to see what I get. Or delve into the Raspi program to see what the breakout is.

Just a fyi about what you said regarding suburban, k5s being the last year. 73-87 was square body years in 88 the gmt400 came about. But gm still produced r,v suburban and k5 which would be know as blazers and also ton pickups was produced until 1991 as square body. They had v3500, r3550 truck. The v represented 4x4 and R 2x4. So they still made ton truck, suburban, and k5(blazer)in square body style till 1991.

I have a 86 suburban i have converted to TBI, and a 94 thats Diesel OBD1 i remmeber seeing your video years ago, glad i found it again, im needing live data for my 94 k2500 diesel suburban id like to monitor boost and my transmision temps etc. any links to where to get this for my pi?

So, I have a 1976 gmc motorhome with an olds 455 running gm tbi from 90s era truck. The ecm is flashable from dynamic efi. They have a windows only based software and I’m looking to read data from the ecm with a pi. My end goal since it is a motorhome is to have a bit of lighting control (home automation) monitor solar, etc. and then display a digital dash similar to an airplanes glass cockpit. I was looking at node red to read rs232 to ttl serial data, but if you already have a software solution, I’d consider that as well. Any tips?

good video my brother

Could this setup show boost on a small turbo diesel 93 Mitsubishi Pajero

did you build that, or did you buy it from Mr Steve? i would love to have one for my f body Trans am. I love your truck by the way!!

Can this be done with Honda? Would appreciate some advice.

I want to do this in my vehicle. I have a 1991 chevy g20 van 4.3 v6. I just received my USB cable for red devil river and got a monitor already. Im finding it difficult to get the driver to work with my pi. If you have some time I could use some help.

I'm trying to set this up for my 94 GMC Sierra and I have one issue. The "make install" fails at cp: cannot stat 'aldl-tty': No such file or directory. I look and I see that the aldl-ftdi and the aldl-dummy files were created, but not the aldl-tty. Any ideas? Thanks!

That is really sweet. Will it tell you the error code if you CEL comes on? -dave

here is the post that explains it how it's done: fbodytech.com/misc/raspberry-pi-dashboarddatalogger/ you're welcome :)

I like that small monitor, where did you get it?

Do you know if this would work for my 1990 Chevy V3500 with the 350 TBI smallblock and the th400 transmission?

I downloaded all files but new to rasberry pi. I have the pi 3 but unable to get the program to install per your instructions. what am I doing wrong?. or is this over my head for a small easy to use computer.lol

How would I do this on a 91 s10. Would I need to write my own code to be able to read my ecm? Is it difficult?

where did you purchase it at..

I'm looking for the aldl-IO download. how does on acquire the software for raspberry pi. I want to do the same set up in my 1994 7.4l burb

The last cold start showed 180 coolant temps. Not a cold start I'd guess.

how is this done it have an 89 not sure what is needed to do this? I know the pie and screen but what about the rest
