90-94 GM Diagnostic interface cable for port injected motors

This interface connects your PC or laptop to your cars OBD1 diagnostic port via one single wire that can be plugged in or hard wired in.  When used with the proper software it will show real time data from all the engine sensors and ECM.  This is a very use full tool for trouble shooting engine performance or just to see how the engine is running.  This is a must have for data logging.  This interface is primarlly used on 90-92 TPI sytems and 92-94 LT1 systems, but the software is the determining factor. A list of compatible software packages is listed below, I'm sure there are many more out there but this is what I have found:

Most software can be downloaded free from there providers
TTS datamaster
Tunner Pro RT
ECM831
PCM comm
and most all software packages that use a RS232 interface.
(download links are provided in the instructions)

Please make sure that software is available for your application before you purchase.
System requirements are that you have one 9 pin serial port open or the proper USB to serial adaptor, and a 12 volt power source ie (cig. lighter).
