I have a sliver lable 413, i dont really want to get a chip for it yet but i might have to because of the possible ews. Its says 11/93 on it so there is a chance it doesnt have ews. I would love to test it out with someone who has a 24v in the I.E. I guess it doesnt have to be an 24v e30, just a pre ews car. Let me know if anyone is game.
