If you are asking which computer jeff put in the black one...call and ask him because it isn't necessarily the one that is supposed to be in the 88 manual...
If I remember, 12 years ago I did some testing with computers for auto and sticks. put a 5spd computer in a auto it will pick up. the auto's timing was a little less than the 5spd. Also if you take the 93 cobra one out of the cobra and put in a 5spd 9al the car will also pick up. I tested all this back in 94-95, just make sure you get a mass air meter for 24lb injectors and a none cobra ecm!!!
