I have changed my mind, and want to go for the NTC type IAT sensor. My vems is set up for the PTC type.

What to do?

A: ?


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?

A:

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

Q:

What firmware to use? can i use 1.1.23 12x12?

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.
Q:

How to upload tempsensor files?

A:

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?

A:
