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.
