Does anyone know where I could find a tested ECU N327 18 881? Ebay's no good for this service number.

 

yes, you can find it on the forum here. just scroll down on the front page to 2nd gen parts for sale and new post WTB ECU N327

 

katkaroto is right.

You can also call Mazdatrix. They are pretty good at finding rare parts.

 

A N326 will work just fine if you don't find the N327. Interchangable. Two peas in a pod thing.

 

i have three of them. they aren't tested but i'm sure they work. they were from a friend who was an avid rotary rebuilder, so if he had them i am sure they work. he moved and had to get rid of all the parts he had.
