Hi everyone,
I’m considering using EMU Pro-8 as a second ECU on a biturbo V8 Audi controlled by Bosch MED17.1.1 OEM ECU. Apart from reading out additional sensors and logging, I need two functionalities the most:
- dual DBW control (OEM ECU only supports single throttle body)
- secondary rail with 8 port injectors for supplemental fueling (OEM ECU supports DI injectors only)
For the second functionality, I was considering tapping into crank position sensor and receiving MAF signal over CAN while running EMU in open loop - that would allow Pro-8 to follow the fueling logic of OEM ECU and operate as part of its closed loop control. Port/DI share would be controlled by a 3D map in OEM ECU in this scenario. Unfortunately in current software there is no possibility to receive MAF or MAP as a CAN signal, probably because these sensors are deemed too important?
What would be the best way to proceed there? Wait until (and if) some CAN MAP/MAF receive functionality gets implemented, or is there already a way to control fuel trim via CAN?
