If you have some other connector configuration other than the GM 12 pin (such as Lotus cars) or a mid-1980's GM car with the serial data on pin D, buy theВ bare pin cable. Pin M indicates 8192 baud and pin E indicates 160 baud rate serial communication speed. This cable works on cars that have the serial data pin on pin M or pin E of the GM 12 pin OBD1 ALDL connector, which is most every 1982 to 1995 GM car. See our GM OBD1 home page for references and diagrams of the connectors styles.

This cable is the most convenient to use if your car is equipped with the 12 pin connector style, as it allows you to just feel under the dash to plug it in. This cable has a 12 pin OBD1 connector shell to plug in under your cars dash to interface to your cars ECM.

Then you can buy a chip burner and new chips (and maybe a chip adapter), THEN you can actually burn new chips and 'tune' your truck.I will probably just buy the moates APU1 because it will read the current chip in the truck, emulate the chip (plugs into the chip socket in the trucks ecu and lets you tune in real time so you dont have a burn a new chip every time you want to try tweaking something) and then burn chips once you have the tune where you want it for now.of coarse this all also takes knowledge on tuning and lots of time and patience.Дrip and I (mainly TheDrip lol) are working on finding the best definition file for TunerPro RT so those with this 'adapter' or similar cable setup can use TunerPro to data log and go from there.OBD Diagnostics, Inc. Shareware DOS-based software for ALDL vehicles ECM852 Serial ALDL Software (direct download link) This is the DOS-based software for GM TPI and 93 LT1.

Thanks for chiming in Drip, like he said, this will just let you 'scan' the truck aka check engine codes, reset codes, monitor i think it is 37 or so different sensors, and soon be able to data log (record) those sensors and that will allow you to see where you can make improvements in your 'tune'. And take your ground and hook it to the ground pin of the ALDL port which is pin 'A'. Now you need to take your setup out to your truck and hook the wire that you connected your RXD and TXD pins to and hook it up to the ALDL port 'M' which is the 8192 baud data pin. You may need to select witch COM port you are using so it knows which USB port to look at. It shoud find the module and tell you, you are ready to connect.

After you install and have your usb module hooked up to your computer, you can follow his instruction in the program and do the ALDL interface test. Now you need to go to and download GMTDScan Basic for free.follow his instructions and install it. I did do a quick google search to make sure they are out there and I found a bunch of links so don't give up! Since I did not have to do this, I can't give you much info on manually finding the driver.

If you do not get this and/or your computer fails to find the driver on its own then you are going to need to google search for a 'FT232RL USB driver' for your operating system. Yours might not say 'COM3' like mine, it will depend on what USB port you use. When you get it and take it out of the package it should look like this:

(item# 260917151841 from seller: polida2008) for $9.99 with free shipping.yes it came from china and took like 2 weeks to get here. I bought the 'Arduino FT232RL USB to Serial Module USB to TTL level + USB Cable + dupont #248' on ebay.

This how to will show you step by step how I took the info from the above thread and made it work with Engh Motor's GMTDScan Basic all for the total price of $9.99!ДЇirst thing you need to do is purchase a FT232RL USB to Serial Module. Ok, first off, most of us know you can download GMTDScan from and buy an ALDL cable that supports 8192 baud communication and scan your truck.but the cables seem to run $55-$75 and up! Which I found a bit silly.if its a cable, then you can build your own.After looking around for a while and doing research on what other people have done to make their own ALDL cable I came across something interesting.most people are making cables that go to a computer serial port.which is simple but silly because most laptops don't use serial anymore.so you would have to covert from serial to usb and that cost money and a pain in the ass.so i found a guy who did it a little simpler over on another site.(hope this is ok to post for educational purposes).
