Hi please describe your car/engine so other installers more easy can help you.
The H2 is the exact firing order of the ign outputs more info at this page http://www.vems.hu/wiki/index.php?page=GenBoard%2FManual%2FDigitalOut%2FTable
If the car is Audi s2 you will find some useful info in this page http://www.vems.hu/wiki/index.php?page=MembersPage%2FPeterJensen/AudiSwiring

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.
I have allso downloaded the 1.1.27 firmware. But my fuel p.relay went crazy when i uploaded it..
Q: When i downloaded megasquirt, there was a PINOUT picture included.. Is there a simular picture for the Motronic 55 plug?

Q: I have some msq files for the motronic 55, but i can not understand the ignition outputs.. what is H[2]? and what does 04..00 stand for? Does this have any thing to do with the fiering order?
