## FAQ
|
|
|
|
Q: How about 6 cylinders sequential on microRusEFI?
|
|
|
|
A: The microRusEFI ECU is primarily a 4 cylinder ECU. At this time the testing for safety, reliable control, and consistency have not been completed for running the microRusEFI ECU on a 6 cylinder engine. This is something that we are working on and could be added at a future point.

|
Q: what about stepper idle?
|
|
|
|
A: yes microRusEFI can drive 4 wire idle air valves see setting at https://github.com/rusefi/rusefi/pull/3749
