Jep,
If your talking about your 83 CJ, then the altitude is part of the computer. There is a wire on the right side of the engine that runs in the same wire loom as the dist and oil sending unit. Its a black wire that looks like it should be grounded....in fact, most people think it is a ground and bolt it to the block with the other ground wire....like I did. Anyway, when its grounded, the computer runs the Carb leaner. With it ungrounded...it runs richer. If you go over 5000 feet, it should be grounded.
