All KZ-F's which were 86-88 model year were computer controlled for lock-up.
If you are looking for a lock-up controller/computer, I have just installed a lock-up controller on a KZ-F in a '70 Chevelle which is a computer that monitors speed, 4th pressure switch and uses the trans pressure rise and fall as a TPS to control and custom program the lock-up function. Let me know if this something you are interested in.
