Engine management / e30 m42 "175" ECU variations, how to decode white label ?
« on: September 20, 2016, 07:03:09 PM »
Ok, New to the forum and hoping to harvest some technical ifo from those in the know, here goes.
I have done a lot of searching and have found no info here or on the internets regarding the 90-91 318i / 318is "175" ECUs and the variations. Does anyone know how to decipher the white labels / stickers on the case?.
I have 4 1991 "175" ECUs but they are all slightly different inside, meaning slightly different circuit board layouts.
In other words they all have the same part number and all came out of 1991 318 series cars but are all different from one another. One unit even has a an additional circuit board standing on pins above the main board. what gives?
Can anyone shed light on this??
Thanks!- Jeff
