I noticed an ECU on eBay today. Its listed as 2009 and the engine number is P611E-0023002. I added it to the list in the OP. This is the highest engine number so far. This means there were at least 23,002 RSWarrior engines built as of 2009. The 2010 Canada models are in addition to this.
Just moving the Update post to the end so the same data exists in the first post and the last post.
Here's the 'Engine Numbers' from either the ECU or the Engine case, separated by model year. Some
have been posted here, and some have been received from other confirmed sources.
I've also inserted this information into the Original Post (Permalink #1).
