first pitcure have MAF sensor on the hose of intake



the second doesnt have any MAF sensor on the hose

Both are OEM, and were used in both zenki and kouki ae86's. The MAF models were for countries with stricter emission regulations (USA/Swiss)
Most of the other countries got the MAP sensored engine.
Major differences between the two:
MAF version has low compression ratio (9.3:1), bluetop MAP engines have 10.1:1 compression ratio and make slightly better power. Also, MAF engined cars usually have catalysators too.

You can try to check the ECU:
