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 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. Title: Re: ecu letter designation Post by: createddeleted on December 30, 2011, 11:47:30 AM 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. Title: Re: ecu letter designation Post by: Zac on December 30, 2011, 03:05:54 PM Does this list of ECU #s to cars help? Posted elsewhere on this forum previously but not sure how popular that thread was.
