Honda as a performer of electronic assemblies for Civic 4, 5 and 6 generation companies have chosen Denshing and Keihin, very often you can find their logos on Board ECU of the brain and the injectors. As microcontrollers brain ECU was selected two companies, it is NEC and OKI. Moreover, NEC raised more in SFI, in view of its reliability and simplicity, the OKI company mainly engaged in the production of chips for its equipment — printers. Microcontrollers series M66 OKI was used in the ECU OBD0, OBD1 and OBD2. They are based on the core NX-8. The only difference is the different peripherals of the microcontroller, memory, speed, and course type.

most Often used in the car without the VTEC system, D13, D14 (except D14Z), D15, D16. Honda Civic, Integra, Partner and others. An interesting feature of the brain P2C on the block D15b (D15Z9) is able to control the variator.
