is this ecu obd-1 or 2?

[240DRFT]

i have an s14 auto ecu that i got for free but i dont know whether its obd1 or obd2. The letters and numbers on the sticker say A18-B24 EB5, then theres also a another little number on the sticker that says 2X08. can anyone tell me if its obd1 or 2 from the numbers and letters?

do you know what year it was from? im not sure but i dont think nissan switched to obd-II until 1996. hopefully someone who knows their codes will be able to tell you for sure.

no i dont know what exact year but it came from a zenki s14 so its a 95 or 96. And oh ya i forgot, it has two big letters on the sticker, PA
