This is for the 525 ECU, not the 173!

This is for the 525 ECU, not the 173!

so what are you trying to say?
came out of my 89 325i with 525 ecu.

[wodcutr]

I am saying that it is not for the 173 ECU which most people have in their late model cars. It is still for an i car, but will only work with the 525 ECU...I was trying to clarify that fact for any potential buyer!

what kind of gains can you expect this to produce?
what ecu is in my '87 325is? will this work in it?

you need to open your glove box and see what ecu you have, if the last 3 digits are 525 it will work.

15hp/tq increase on 91 octane.
