is there such a thing out there? I can find them for obd2 but not obd one. some places I take my jeep I really wouldn't want to take my computer. and im using a 7747 ecm for now but will be going to the 7427 when I get used to tuning

that requires me to take my laptop with me. im looking for a little black box type of thing. some thing I can tuck up under the dash run the trails all day and adjust the tune back at camp where my computer will be nice and safe

i'm certain i've seen an arduino/AVR that writes CSVs to a SD card from data it grabs over ALDL. i want to say one of the aussie guys came up with it?

Look for older scantools. Even better... GM used to have a tape recorder that could record data and play it back!

[diver14_98]

I would be very interested in some thing like that but I have no idea what to do when it comes to coding.

I rolled my own.. wrote the software.. used raspberry pi. hundreds of hours invested. under 100 in hardware including dash display. fun times.

it had wireless.. connected automatically when I got home analysed and uploaded data to my laptop.

not for the faint of heart

I did it because there is no such thing you can just buy

actually wait

there is

old cellphone with aldldroid.. done

I would

Back in the mid 80's there was a company MPSI out of Sterling Heights MI that had the tape recorder for OBD-1. GM had the CAMS machine but the box that plugged into the ALDL had a button the driver had to push when a malfunction occurred. Both are extinct. MPSI tape recorder had to be loaded into a "computer". A XT from IBM with a 5 1/4 inch floppy drive. Bet ya don't even remember them things?
