FC ecu?

Hey guys I was stripping out all the old nasty carpet padding on the passenger side and
I removed my passenger foot plate and under it there was this computer-


My car was converted by the previous owner
to a fc harness for a 13B swap that never happened.
I just want to make sure its not something thats needed.

Also I'm making a custom guage cluster with
autometer guages and I need to know what
type of fuel guage to use. Theres Ford,chrysler
,and GM guages. Anyone here know which will
read correctly with the stock sending unit?

Thanks,
-Austin

that's the stock 12A emissions control unit. put it up for sale, they go bad, so someone in a place that has to pass smog will be happy to buy it

you have to look in the FSM. the autometer one sucks, but it should work. we have one in the race car, and it has like 12 different modes, so one of those should work.

actually i shouldn't say that it sucks, it looks like the honda might suck, but the gauge isn't damped, so its useless when you're moving
