Title: ecu letter designation
Post by: marcello7x on December 28, 2011, 06:48:13 PM
New to the site and have only read about tuning, never done any prior. I'm doing along of reading and want to try to start with a modified tune and tweak it to gain knowledge. My question is how do the last 2 letters of the ecu part number work. Must the numbers match for the file to work?

I have a spare ecu, must it have the same letter codes as my current ecu for it to work in the car?

The car is a 2004 VW Jetta 1.8t awp.

I found some more information on the net stating that NK, HS, SK are north american ecu's. the first two superceded by SK.

I bet most of you guys know this stuff, but since i asked and found it i figured i would post it incase someone else comes along looking for an answer.

My current ecu is an NK, while my spare is an SK.

They're pretty much all interchangeable. I like tuning my HN over my PL. Its just different definitions that you're working with.

i briefly covered this on my post in another forum.

Does this list of ECU #s to cars help? Posted elsewhere on this forum previously but not sure how popular that thread was.
