ECU tune Transmission control unit?

[longassname]

The 96 TCU I did was labled MQ and is under the steering column. It uses the same processor as the obd1 cars and I have done the ECUtune performance mods to it, given the firmware to Phil, and posted the code for the ECUtune mods to Phil's gearshift map thread.

The TCU I have as a 97 is the same as your MY. So I guess there is a break somewhere in 96. The MY uses a different processor and does not have an external memory socket.
