I just checked my car's ECU.

I have an 88' DX with a DOHC ZC in it.

My ECU says written on it on the top in marker:

SOHC EF3-5200051
ZC

and the serial # on the side is:

37820-PM6-903
625-300109


I am just wondering, does this have the 28 pin EPROM? I am curious if i can use this with Ghettodyne 2.2?

ANy help is appreciated

it's a pm6, and yes, i beleive ghettodyne supports the 88-89 pm6

cool ty

yes it does support it, but its hard with a 88 or 89 an 90 or 91 would be easier.

thats what i am trying to find out. Is the year. How do i know what year it is?

you neglected the most important piece of information.

Generally the year of the ECU is stamped in ink on the side. Rarely "89" ECUs are actually for 90 cars and have EPROMs.

look at that picture. In the top right, notice IC19, a 28 pin 38256. If your ECU has that chip, it is a 90-91.

Look here:

That has good scans towards the bottom of the article. If you've got an external EEPROM, then it's a 90-91. If not, it's 88-89. Simple. -Z
