I wrapped mine in tape for now and ordered a micro to mini USB cable. Connect the RXD or TXD on the board to the the 8192 baud rate terminal G on the ALDL. Connect the ground terminal marked GND on the board to the ground terminal A on the ALDL.ģ. I used a short piece of light blue wire.Ģ. Connect the RXD and TXD together on the board. There are only three connections we need to make.ġ. You will need to know which pins are which on your ALDL. There are three connections on the FT232RL we are concerned with right now. You can just run bulk wire directly to your ALDL and mount the USB plug somewhere convenient. Later on, I plan to permanently mount one of these to my K5. So, I also bought a 12 pin ALDL to 16 pin and cut off the 12 pin for my project.
I wanted an adapter that I could use as a portable scan tool. There are several options and I ordered the cheapest one I could find. It is what will convert the data coming from your vehicle to your modern computer device via an USB plug. This is a part that is made for an Arduino. An Arduino is a little open source hobby computer. I however, am a cheap ass and didn't want to spend the money. If you will be scanning a TPI or other mass airflow car, I would suggest picking one of these up.
There are wired and Bluetooth models available. There are several companies that sell adapters for $55-90. You will need to build or buy an adapter so that your computer can talk to your car. That is what we will be focusing on today. I thought this was the best fit for my purposes.
I made my own adapter and used my android phone with the new ALDLDroid app. This can be bought or assembled.Ī Windows or Android computer/tablet/cell phoneĪn application/software for you computer/tablet/phone Why here on Arfcom? 'Cause all things belong to the Arfcom.Īn adapter that connects your car to your computer. I don't consider myself very tech savvy and wanted to lay out a simple tutorial for simple people like me. Some engine control modules (ECM) use a different baud rate and data terminals. It may work for some of the other models, as is. I'm just talking GM TBI and diesel stuff today. There are special steps and different wiring required for different vehicles. This process will work for a litany of other vehicles.įiat/Alfa/LanciaRenaultVolkswagen (Bosch Motronic) My scan tool is the GM factory tool and it only does OBD 2. Most professional scan tools are capable of doing this. I was interested in reading live data on older GM vehicles to aid in diagnostics. : LEDs to indicate power on and ALDL bus activity : Logs four external analog signals when used with our 'ALDL Scan' Android App. : Switch selectable 10K resistor across A and B pins (required on certain vehicles to enable ALDL mode)
: Compatible with most 1982-1995 General Motors (GM) vehicles.
: Most MS Windows applications that use a COM port to communicate to ALDL at 9600 baud : ALDLDroid (Demo Video) Get ALDLDroid here! Analog channels can be monitored and recorded right along with the ALDL data being read by the application.
This allows for the connection of devices such as wide band oxygen sensors. When used with our 'ALDL Scan' application, the user can also log four additional analog data channels via the rear RJ45 connector. The adapter can also connect via Bluetooth to laptop computers for use with computer applications such as 'TTS Datamaster'.
This adapter can be used with our own 'ALDL Scan' Android application.
Our '12 Pin ALDL OBD1 Bluetooth Scanner / Code Reader / Adapter' allows for the monitoring and recording of General Motors (GM) vehicle performance data to the user's Android device. : 12 Pin ALDL OBD1 Bluetooth Scanner / Code Reader / Adapter (MK II)
