The sticker isn't on the side of the ecu. I just wanted to know if their is any other way to tell. I will post pics just dont know how.

 

If you have a photobucket account (if you don't, sign up for one) upload the picture to their site.Once uploaded you will see the picture.Move your cursor over the picture and you will see sharing options.Copy and paste the one that says IMG CODE and paste it here and your done.

A picture of the internals will tell you if it's p28 or at least a vtec convert p28 equivalent ecu

 

if u take off the cover there is usually another sticker on the inside on the grey plugs. if i remember correctly

 

That's probably been removed as well. Since the stickers are removed, chances are it was a non-VTEC ECU that's been converted to VTEC. A picture will tell all, as stated.
