Series I PCM-ECU Part Number Listings

I have been asked many times for a OEM Part Numbers for RX-8 ECU or PCM.

These are ALL the updated Series 1 Mazda OEM Part Numbers for the North American market.
Some now are not brand new but re-manufactured and tested units, those have a 'R0' at end of Part Number.

The Re-man units from Mazda also has a $200 'core' return/deposit which is refunded when old unit is returned or supplied back.

Contrary to popular belief there is more than 1 Genuine PCM for the Series 1 RX-8.


N3ZC-18-881R0K California 4 speed
N3ZA-18-881R0K Federal 2005
N3ZR-18-881N California 6 speed to November 12th 2007.
N3ZT-18-881N Federal-Canada 2008


N3ZD-18-881R0J California 2005
N3ZB-18-881J Federal 2005
N3ZP-18-881L California 2008
N3ZS-18-881L Federal-Canada 2008

IF you are after exact confirmation on which new ECU/PCM to order, please PM me your FULL VIN #.

Please Note: The tear off or 'stuck on' Part Number(s) label that Mazda installed or used originally on your car at production may/has changed, the new or reman units have a different issued part number, see new replacement lists above.

This applies to most vehicle installed parts on your car which in most cases does not resemble the issued replacement part number.
IF you are buying a used or a part out PCM/ECU as long as the Part Number is the same as your original, all will be fine, it will still have to be configured though with Mazda IDS.
