I bought MM3 used, and it's blank without a tune.
I wanted to get a hold of one for a while, and this became available.
I was looking to use it as a gauge to start and add tunes from DRD, who I've followed since before everything got ugly.
I am looking for some help!
I only had the MM3 plugged into the OBDII, and it caused warning gauges (engine temp hot), low oil pressure, tpms, and Park light flashing dash lights flashing.
I will be calling MM3 to ask questions tomorrow as well.
Thanks in advance for your support.
