New GUIs: StoppingDistance and Acceleration
Being a bit over the average interested in brakes, brake configurations and testing, I had "Include Stopping distance" as a part of the Performance GUIs on my development backlog.
Added WheelSpeedDifference to the BrakePressure GUI
At the race track there is great information in looking at the difference between the wheel speeds at each axel. The wheel speed information is hence merged into the brake pressure GUI, which already have the instant wheel speeds.
Solution for OilPressure, BrakePressures and GearBoxTemperature to CAN
Next up the backlog has been to calibrate the oil pressure sensors and to fine tune the software. A 0-100psi pressure sensor is mounted in an oil distribution block for the M54 solution. For the S54 solution the oil pressure sensor will be mounted directly into the spare M12 location in the oil filter housing.
Adaptive Light Response control of the airVent Display backlight
The display unit used in the airVent Display is a TFT with LED backlight. The backlight can easily be adjusted - manually. However, due to severe light condition variations, manual adjustment is not a practical solution when using the display in an application in a car.
First in-car test airVent Display E46 M3
Due to winter time and practical considerations, an E46 325ti has served as a test mule for the test of the airVent Display. Have come so far no that I could not resist the temptation to try it in my E46 M3 based car.
Test of Lambda values, IAT and Coolant Temperatures
Function testing the Lambda values, IAT and Coolant temperature read from the ECU via the KBUS and redistributed to the CAN bus using our KBUS2CAN solution. The airVent Display picks up the CAN messages and displays the values.
In-car test KBUS Brake Pressures
Yet another in-car test done. When running without direct reading of the brake pressure sensors, the brake pressure can be read from the MK60 via the KBUS and redistributed to the CAN bus in a custom CAN message.
Test use of Cruise Control Buttons
Even thoug the screen on the airVent Display is a touch screen, there is also support for using the Cruise Control Buttons on the multifunction steering wheel to control next/previous/home GUI Page on the airVent Display.
First in-car test airVent Display
Found finally a time slot to test the airVent Display in one of my cars. Had to make a cable harness for easy test of the prototypes before the test could begin.
Race Engineer Course
Had the great pleasure and opportunity to participate at a Race Engineer course. The course was arranged by Norwegian Speed Factory, and the coach was the legendary Michael Zotos.
KBUS2CAN
A KBUS2CAN module had to be made. Not all interesting data is available on the CAN bus. Some data is only aviable via the KBUS and needs to be extracted before retransmitted onto the CAN bus in custom CAN messages.
CAN2HMI
CAN2HMI controller needed to be developed in order to interface the airVent mounted HMI touch displays.
Bench test airVentDisplay
A video from the latest bench test of the airVent Display is made. The video is found on Vimeo, and the link is airVent Display prototype test.
Analog2CAN
Analog2CAN modules for reading pressure sensors (0-5V) and temperature sensor (RTD/PTC) are developed.
MK60 Emulator
An MK60 emulator is developed in order to serve those running the E46 M3 MK60 ABS in non-E46 M3 cars, e.g. for those running an MK60 in an E30.
