Ok, tonight my bro gave me an ecu. Problem is, he has no idea what car its from or if it was auto/man. How can i find this out?

Reason being: Im about to chip my ecu and would either like to chip this one and use it so i keep my stock ecu just in case. Or i'd like to chip my del sol ecu and keep this one as a backup in case I kill my ecu during the chipping process.

Here is the info I see on the sticker on the side:
37820-P06-A01
740-621488
APX

it also has a stamped date of FEB 24 1995 (might be 93) hard to read...

:edit: also, if this ecu was from a non vtec, what issues would that cause?
