Computer Question

[Sancho]

Hi Its been while but I am having trouble with a client's SN95 Stang. Costumer stated that they swapped a 5 Speed tranny from a Automatic but still using same EEC computer from the Automatic Transmisson also noticed that VSS Veihicle Speed Sensor is unplug or no working. MY question is are Manual and Automatic EEC computers interchangeable??
The probem with the Stang is that ignition cuts very quickly like for second then grabs again specially when when I put a load on throttle, To be more specific if feels like the rev limiter issue but this problems happen at all RPM Example #3, 4, and sometimes even 5 RPM. All ignition components have been replace with new unit and still problem duplicates. Thanks in Advance and please let me know if anybody know what could cause this issue

Yes they are interchangeable - from auto to manual, but not the reverse - you do need a chip if using an auto PCM in a manual to shut off the auto functions. The VSS is necessary for both auto and manual cars.

I had the same problems when I did my tranny swap, I had the manual computer, just hadn't swapped it out...didn't know where the thing was hidden. Drove around for a while like that, then one of the stang mag's did the swap article, highlighting the computer location. Swapped it, no more ignition problems. This was back in 96, before the populairty of a chip. As Don said, a chip will take care of it or put in a 5 spd computer.

good luck
