Hi :)
Need som help setting up my VEMS Motronic-55.
I have connected vems to the Motronic-55 plug. uploaded the 1.1.23 12x12 firmware, and calibrated TPS and battery voltage. But how to calibrate MAT and engine coolant? I`m using the standar AUDI PTC MAT sensor. I have the VEMS "IAT" sensor allso, but then i have to change a resistor. Any clue what resistor to use, and where it`s placed on the board? Pics would be great:)
A: Don't use 1.1.23. See this page: MembersPage/MattiasSandgren/OskarAudiSFour
Download 1.1.27 on the MegaTune page and go from there.
You have to use the tempsensor_upload script that comes with the MegaTune package to upload a firmware containing the correct temperature tables, see EasyTherm and EasyTherm/SensorTable.
Q: When i downloaded megasquirt, there was a PINOUT picture included.. Is there a simular picture for the Motronic 55 plug?
