Question About ECU's

This Original Post has been cleaned-up removing some of the early questions I had asked in favor of providing the known details.









Among other numbers molded into the ECU case:
  • We found that all known 2002 ECU's have the number 5PX-00 molded into them.
  • We found that all known 2003+ ECU's have the number 5PX-01 molded into them.
  • We found that all know Speedstar ECU's have the number 5PX-09 molded into them.
Part of the reason for investigating this is to help identify Model Year (Yamaha factory build year) for Warrior motorcycles delivered without USA/ISO format 17-character VIN's. Additionally, out of curiosity, it can answer the age-old question 'how many RS Warriors were built?' because the engines for Original and Midnight Warriors come off the same production line.

If you have not posted here alrerady, please:
Check your Frame Neck's 17-character VIN to identify the Model Year.
For 11-character VIN (Frame Number) and Special Build Frame Numbers, see: https://www.rswarrior.com/forums/13-t...odel-year.html
Check the sticker on your ECU (or the engine case) for your Engine Number.

The Engine Number sequence is as follows (example): P611E-0006999 / *35P611E0006999*

Thanks to all who can participate. I know we all look forward to what-ever we might learn!

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.
This information has been copied here from the original location toward the end of the thread.

2002: 000007, 000168, 0000261, 000393, 0002200, 0002967, 0003370, 0004147, 0005129

2007: 0019736, 0020512

2008: 0020815, 0021402

2009: 0023002

2010: (Canada only) (none participating yet)

2011: (New Zealand only): (none participating yet) (Believed to be 2009's)

Why is this helpful? See: https://www.rswarrior.com/forums/13-technical-discussion/147350-service-manuals-model-year.html

Note1: No data has been provided for Speedstar ECU since there is no Engine Number information on them.

Here's where I am on this. I've recently been told that for USA bikes:

The 2002 Warrior, which has CDI Ignition and is shown as using ECU Part# 5PX-8591A-00-00, should have 5PX-01 molded into the ECU. This appears to be supported by the 2002 Parts Manual.

The 2003+ Warriors, which have TCI Ignition and are shown using ECU Part# 5PX-8591A-01-00, supposedly should have 5PX-04 molded into the ECU. This appears to 'possibly' be supported by the 2003 Parts Manual, but in fact its sorta cloudy and indirect.

So I checked my 2003 which has TCI, and my 2003 ECU has 5PX-01 molded into it.

Would it be asking too much if a few guys would look under their seat, and post what model year they have, and what numbers are molded into the plastic case? These are molded on the opposite side from the white "Engine" label and bar code sticker.

Mine is a 2003, and has these numbers molded: F8T914 73 5PX-01 2905
The sticker on the otther side states Engine# P611E-0006447 / *35P611E0006447*

I have a spare ECU with these numbers molded into it: F8T914 73 5PX-01 4216 (not sure what model year it came from).
The sticker on the other side states Engine# P611E-0011691 / *35P611E001691U*

Thanks to all who can participate. I appreciate the assist, and look forward to what-ever we might learn!
Prof - i have 2 ecu's - my bike is a uk opfficial 2003 so i'll check that one ..the other spare was from a bike Gav knew of [not sure which year] but i'll take a deko - jason's is an import 2005 so that might be interesting, and stew is another 2003 official bike like mine...let you know...new sport spotting the ECU lol

Thanks! It will be nice to confirm if the ECU is indeed universal across borders and model years! One day, possibly, this will be handy for those like us who intend to keep this beast a very long time.

I've got a 2007 Warrior (title says: XV1700PC S) that I think is a California model XV17PCW. The ECU part number is: 5PX-8591A-01-00. The molded number on the case is: F8T914 73 5XP-01 6913.

Bought my 2008, new, in 2010 from Bert's, So I'm pretty sure its a CA Model.

Engine # P611E-0020815
*35P611E0020815S*
Molded # F8T914 73 5PX-01 7521

one thing I noticed interesting, I was looking at my CA Reg. and it lists the Eng # as P611E020815.

Alot of Common #'s here. I hope this is what you are looking for.

Great start, hope you'll all keep 'em coming.
So far:
It appears our Engine Model Number is 35P611E, maybe?
It appears the ECU's for USA49 and California are all 5PX-01. [added: there's one 5PX-00]
It could be the ECU's for the UK Official Imports differ . . . we will see.
It could be the ECU's for the UK Grey Imports are also 5PX-01, we will see.
Maybe Bruce and some other Canadian guys will chime in w/data?
I wonder if the 4-digits after 5PX-01 mean anything?

Oh, jff:
The engine numbers ending in S are a factory speedstar build, less exhaust.
The engine numbers ending in $ have factory enhancements (part speedstar).
OK that's a lie, "jff" = just for fun I have no idea so might as well have fun hehe.
