engine computers

Is there a difference between the computers in 5-speed and Automatic mass air cars? I did a mass air conversion, and went to a local hot rod store to purchase the A9L computer. I got it and installed it and everything, and it runs good, but recently we pulled a code for the 'neutral drive switch', which leads me to believe its for an automatic. (my car is 5-speed) Like I said, everything runs fine, but I was wondering if its the right computer. Any ideas?

There is a difference between automatic and manual computers -- but the fact that you're getting a neutral error code assures you've got an A9L computer for a manual tranny car. Mine (the conversion) doesn't have the neutral switch wired up - so I get the same error code. For 10 years and 30K miles that error code has been showing - none the worse for wear.

Ok, thanks. Shows how much I know.

yeah, you would probably have had to do some rewiring of the starter interlock circuit to use an auto puter (which arguably has better timing curves).

good luck.
