96 should have HFM.

The 97 UP ME 2.1 ( also has full OBD 2 ) has full electronic throttle without any mechanical connection. It also has CAN communication between the ECU , transmission and ABS computers.

What started the question is I'm buying a used engine from a 96 E320 to be used on project "A" running 97 ME 2.1 and might make use of the fuel system on project "B" that needs a standalone fuel system.

I'll have a look at the donor car for ASR / snow tire switch. I do have the VIN but don't want to use up too many of my dealer parts dept favors by getting a data card printed. Is there an online was to get a data card?
