Hey all,

I'm working on an Arduino 'ECM' of sorts, however its basically just for sensors as I'm running a VW 1.9AAZ Turbo Diesel (mechanical injection). I'm wondering if I should do as many ECM's require and go directly to the battery for power and ground - or if it is as not as crucial given my needs.

This is not a racecar, just a street car... well, bus. Its a 1976 VW Westfalia Bus. Sensors will be: Oil Pressure, Coolant Temp, EGT, RPM, Boost and Fuel.

Just figured I'd post on here and see if anyone had any quick suggestions. Thanks!
