I put an AFM from an '87 into my car with a cone filter. Everything plugged in nicely but car wouldn't start. I read in the rx-7 performance handbook that its good for a few ponies. When I read it, it sounded like a plug and play. Obviously not. Must have to switch a couple wires.
Has anyone tried this before?

 

actually, do a search on this. there are tons of threads on this. it will work but there is some modifying to be done.

 

Not worth it IMHO.

Here's a link that should help.

Installing a 2nd gen AFM in a 1st gen

 

Thanks for the info guys. I think your right, it doesn't seem worth it. Anyone want to buy an AFM??? J/K
