Hey guys,
Working on porting over some early virtual flex fuel sensor logic to the N55 E series v5.15 firmware with the ultimate goal of being able to have the JB4 closely approximate your ethanol mixture without the need of a physical flex fuel sensor. For those who have a physical sensor installed this will make a great backup/safety system as physical flex fuel sensors are not always 100% accurate. As part of this change we've also updated the test firmware with the N54 logic to scale port injection flow on ethanol mixtures as read via a physical OR the virtual flex fuel sensor. :happy
Once the virtual sensor logic is nailed down we'll get to work on improving the JB4 autotuning functions to better utilize this new data and we're also working on autotuning of base dutycycle by RPM to simplify tuning for larger turbos.
Anyway we could use some customer data on the test v5.15 firmware.
Email me if interested in helping!
