can I install a lamda sensor?

[spawns]

i own a 84 2 door Levin and my question is if i can install a lamda sensor and how?
how about a map sensor?

If you can get the ECU from an early JDM AE86, you can run both
the lambda sensor and MAP sensor. What I don't know is if the plugs
match up, or if they have to rewired.

Some early Euro spec ECU's use MAP but not O2... and ASFAIK some
run AFM and O2. There are different combinations according to the
market in which the car was first sold.
