Is there such a thing as an adaptor that plugs into our 88-95 trucks that can be read by an OBD2 scan tool? If so, do they provide sensor data such as O2, TPS, etc.? Do they work? Is there a better way?

You need a scan tool that will handle OBD1.

There are OBD1 cables, but the OBD2 reader will not work unless it's multi lingual

Download winaldl and buy or make the cable and you can watch all your sensors on a laptop.

There are 5 parts to this

1. OBDI connector and cable goes to data reader/logger module
2. Data reader/logger module
3. Cable that goes from data reader/logger module to a PC, usually a laptop computer
4. Laptop computer
5. PC software to capture read/logged data.

The following handles the first 3 items.

There are a lot of software packages available. One popular package:

Snap-on MT2500 scanners can be bought cheap nowadays, and will give you data as well. I still use the one I bought 20 years ago.

Actron also makes a fairly cheap Obd 1 scanner.

Why all the bother? I bought a OBD1 scan tool from Scoggin Dickey Chevrolet's GMPP Dept. that has quite a complete list of readouts and live reports.

I use a FTDI FT232RL adapter board. The USB end goes to the PC. The pins connect to the ALDL port. Connect GRD on the adapter board to the ground terminal of the ALDL port. Connect the TX and RX of the adapter board together and connect to the data pin of the ALDL port.


This isn't where I bought it, but this is the board I used.

I just wired the adapter at the dash and use a 10' USB extension cable to run out to the PC.


Then, get Tunerpro live and the appropriate adx file for your truck. Use gearhead-efi.com for the adx file.
