Now your better off just getting the A9L computer there the most common. You can use them in any conversion that you want to do. sometimes its better not to ask questions and just do it

OK..... Looks like I've stirred up the Hornet's nest here.

How about the details.

Are the fuel tables in the EEC-IV the only consideration (other than changing Pinouts ??)

I'm not buying the fact that the A9L is the ONLY EEC-IV that'll work for this conversion. As we know, they're getting harder to find and expensive when you do find one.

So WHY are they considered the BEST/ONLY EEC-IV that will work ?? I'd really like to know....
