The RX7 S4e/M0d009 ECU plugs directly into the factory loom, with additional inputs and outputs available on unused pins in the factory connector. The additional pins you have access to give you the following options:
An additional 2 injector outputs
An additional O2 input, and 2 additional 0-5V inputs for logging or other functions like sequential box strain gauges
Additional ignition output for conversion to direct fire
Oil pressure, fuel pressure and oil temperature inputs (plus we read the fuel temperature input and use that in the fuel density calculation)
CAN (Wideband lambda can be connected via analogue input, or via serial.)
GENERAL FEATURES
Modular system, so that people can buy hardware upgrades later as their needs develop (eg additional inputs, outputs, or specific functions, eg drive by wire or built-in lambda)
Wireless communication
Maximum output of 22 (8 ignition, 8 injector, 4 auxiliary, tacho and fuel pump)
3 complementary drivers in the ECU to drive inverse outputs
Smooth transition to direct fire
Drive dual speed fuel pump
Injector staging is automated
Has an option to manually set the percentage of fuel to be delivered in secondary (or third, or fourth…) stages
Handle the factory pickup, the 36-1 FFE trigger with the factory sensor, and the 36-1 FFE trigger with a Hall effect sensor
Great twin turbo control
Fast USB communication, requiring no drivers
Headphone port for listening to the knock sensor while tuning
4 x serial in 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
Tested to MIL-STD-202G, a military vibration standard, which varies the frequency and peaks at 7.5g of oscillating acc
