M1200 ECU
This product is one of the three wire-in universal ECUs we have for our line of Modular ECUs, and is considered to be the most basic. It replaces the e420d Select ECU for a wire-in 4-cylinder / 2-rotor engine application using the technology from our new Modular ECUs. It is worth taking note however that the M1200 can not be expanded or upgraded with more inputs or outputs. The injector drivers are also only meant to support applications with high impedance injectors.
The M1200 can also be used as a plug-in ECU for the NA6 and NA8 Mazda MX5/Miatas with 2-plug ECUs. Otherwise, connectors and looms for a wire-in application are sold separately.

General Features
- Replaced the e420d for 4-cyl /2-rotor engines using the technology from new Modular ECUs
- 48 pin Mate n Lock
- Fast USB communication, requiring no drivers
- Headphone port for listening to the knock sensor while tuning
- 4 x serial ports
- 1 x CAN port
- Power over USB to do loading of maps, firmware etc without having to provide it with 12V power
- 32MB of onboard logging to flash
- Exception logging, able to detect faults and log a bunch of things that happen around the same time to help with ECU setup and tech support
- Bigger maps, more of them, and more dedicated maps.
- Tested to MIL-STD-202G, a military vibration standard, which varies the frequency and peaks at 7.5g of oscillating acceleration
