How Can You tell an ECU is P75, P74, PR4 Etc...What's The Difference? And What Should i Look For?

 

should have a number on it......do some searching for pics on here, i'm sure there are one or two somewhere.......may try a google search too

i'd look in the classifieds for the pic though, people use them for ID purposes sometimes

 

Disclaimer: I don't stand by my words here... I really have very little idea what I'm talking about
there will be a serial number type code on a white sticker on the side of the ECU. You'll see a barcode on the sticker if its the right one. Then, I believe the ECU model is in the 2nd cluster of numbers and letters? you'll see it if you find the sticker though it'll most likely be the only "P" on there

 

ahhh i c i c now it says PR4...Thanks guys...
