PCMcomm
Specifically targeted towards the 1994/1995 F/B/Y body LT1 cars, it works very well and provides you with a very easy to read, no frills user interface. There is a data logging upgrade version available for a very good price.
Carsten Meyer's ALDL Monitor
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. Won't work with USB adapters, and won't work with WinXP/2000. Works great with older laptops on Win98/MSDOS that don't have USB ports though.
Lotus Elan M100 ALDL diagnostic software 'ElanScan'
Free software written specially for Lotus Elan M100
EV1Dash for Palm OS
Peter Ohler's software for Palm Pilot. EV1Dash is a program for Palm OS devices that will collect data from the EV1 and display it on the Palm OS device display. The intent is to provide more information to the driver so that range and performance can be optimized.
WinALDL - 160 baud ALDL reader
WinALDL is a program that reads the ALDL data from some supported ECM types. The data is presented in a way that will help when tuning a car after engine modifications.

TunerPro
TunerPro is a free, donate-if-you-like-it tuning platform aimed at making tuning easier and cheaper. TunerPro started life as GMECM Edit, and debuted in early March of 2003. It was created primarily to tune GM vehicles between model years 1985 and 1995. TunerPro has since grown into a very robust tuning tool and is evolving faster than ever. This project started as an 'educational' project started with a few simple goals: It should be available for free in its essence, it should be better than whats available in its class, it should remain as simple as possible to use.
TunerPro supports GM OBDI (pre-96), Ford EECIV and EECV, and late model Subaru (WRX) vehicles.
EFILive
Paul Blackmore has written this software with lots of graphics in mind, with multi vehicle compatibility the goal. There is a free version (allows up to one minute of data logging - most dragstrip runs are less than that), and the full version is available for a nominal charge.
ALDL_LOG
Another ALDL scanning tool

Free ALDL scanner
TTS DataMaster
TTS DataMaster is an excellent package in the way it's laid out and the data it provides. You can use it 20 times on data recording runs before purchasing a key, and you can view previously recorded data any number of times while on trial, before purchasing a key.
For each of these packages, the proper version or data file for your car's ECM/PCM must be used when you are doing your data collection. Some of these programs have different data files that must be loaded for your car, others have drop down menus for you to chose your ECM/PCM. Read the documentation for the particular software package you are using. To determine which ECM/PCM your particular car has, this ECM/PCM cross reference page may be of use.

There have been at least four different ALDL connectors used world wide (and probably more exist too).
|
Since we are looking at the connector pins, it should be mentioned here that a quick method to see which trouble code or codes are being set in your cars ECM is to jumper the A and B pins of the 12 pin ALDL OBD1 connector with a paper clip.
While the car is off, turn the ignition key forward while this jumper is in place. Do not start the car. The Service Engine Soon (SES) light will flash in a repeating sequence, telling which trouble codes have been set in the ECM. A service manual for your year car will have a chart outlining what each trouble code stands for, or this website can be of help.
This paper clip method will tell you the trouble code or codes set in your ECM, but it will not tell you what conditions the trouble code is being set under, or let you clear the trouble codes on the fly, as the ALDL cable and PC setup will. |
