hi, I want to get one stm based ecu for my personal car for testing, playing with it.


car info, 2001 audi s4 2.7 biturbo engine. first starting with completely stock engine, just ethanol, injectors and ecu.


hw info:

1 crank trigger vr 60-2

2 cam triggers, hall

2 egt sensors, oem, will check specs what output they have

1 dbw throttle What is the resistance / max current ?

1 flex fuel sensor (frequency signal ?)

2 lsu4.9 lambda sensors, one is ok too

6 high-z injectors

6 logic level coils


future 2019 year updates

will convert to single turbo

probably with water cooled ic + planning to add additional sensors:

+pre throttle map sensor for more precise boost control and map sensor after throttle for main fuel calculations

+air temp sensor after the turbo, to see how efficient we are

+charge cooler water inlet and outlet temp sensors
