No JCW sticker on ECU

No JCW sticker on ECU
So...back story..bought my JCW (04 dealer install[no cert]) few months back, just cleaning it up ect, then as i was reading on the forums all the things that should have JCW "stuff". The only thing i hadnt looked into was the ECU, so i pulled it. It doesnt have the sticker of when it got the flash. So do i possibly have an r53 with all the bolt on JCW stuff or could they have 'forgotten' the sticker. I know it has the r53 injectors and airbox(pictured)...so its not the 210.

I did a fair amount of research about pulleys when I considered going to a 19% ratio (see the below thread). The pulley is measured from where the inside of the belt contacts, so the outer edge of a the JCW pulley is just shy of 2 1/2" as I have mine next to the laptop as I write this post. In approximate numbers the belt is about 1/8" thick, so take that 1/4" off the 2 1/2" outer diameter and you get the 2.285" that has been posted numerous other places. The S pulley is 2.565 that would make it about 2 3/4" at the outside.

Thanks for the info. I guess I'm qustioning the authenticity of my JCW; with no sticker on the ECU, the fuel door doesn't have the sticker, and the badge on the back isn't aligned with the 'Cooper S'. The reference I'm going off of is

the cert would be nice but that ship sailed with one of the previous owners. My next step is to get over to a Mini dealer to see what tune is on the ECU.

I'm also considering going to a 15% pulley on the JCW engine......would it make much of a difference you think? I'm wondering if the $$ spent would be worth it or not.....

So, i tracked down the original owner(stalker much), talked with him for a few min. He ordered it from the dealership with the JCW options in late 2003, took delivery in 2004. He said that he may still have the cert filed away.
his reason for selling it....problems with the run flats.

Thats a 210 kit. Will have blue fuel injectors and has the flap on the air filter box. If it has the red calipers it will be a factory 210 JCW if not its a dealer install kit
