I use a datalogger and dash from the company Race Technology.
The dash uses the AIM data from the vems to display RPM, temps, etc.
The data displayed on the dash is all wrong, because the AIM data comming from the ECU does not correspond to the protocol given by VEMS. Here is a link to the AIM data which was supposed to come from the ECU. http://www.vems.hu/files/MembersPage/NanassyPeter/AIM_support/AIM-ECU%20protocol.pdf
However Race Technology analysed my data which I had logged from the ECU, and they informed me that it's not the signal it was supposed to be.
Anyone have any info on the AIM data? I guess it's the same data which is used by the Vems Round display.
