Car is an 1988 Firebird with a 350 being run by efi connections 24x with a 0411 pcm. The WCT5 is giving the pcm signal but what does the computer need to be set at to read the vehicle speed. Right now it shows on the scanner that my speed is 1 mph and if I am going faster (above 40 mph) it will read 2 mph.

Assuming the pcm is set for a 4l60e?

Need to know what to set it at for my final tuning session at the dyno.

Thanks in advance
