Does anyone know the part # for this ecu?? On kings page It says 37820-XGS-00N0. And at Takakaira.com (A japan dist) they told me it is 3782-XGS-00N0. So it is the same but it is missing the first zero. I just want to make sure if I buy it from takakaira I will get the same one that king sells. Anyways, any help would be great!

 

The box from Mugen lists 37820-XGS-00N0.

 

Ouch, not a great idea to buy an ECU from Takakaira. Let's say it doesn't work, no warranty, and King isn't going to cover you. Somethings you pay for. It's an ECU, I'd be careful. If it was an intake, exhaust, header, that'd be a different story.

 

In their e-mail to me they said that mugen only makes ONE ecu for the s2000...is that true?? How could it be different than the one king sells??

 

Yes there is one, but King will not warranty anything that is not bought thru them. So if you have any problems with the ECU you are SOL.
