Overview:

My name is Karl Buchka. I am an Electrical Engineering student at The University of Massachusetts Amherst. The car is a 1979 Volvo 242 with a 1995 Volvo 850 Turbo engine (B5234T).

Some details on the car:

VEMS Setup:

Apart from the standard sensors (MAP, CLT, IAT, TPS), the VEMS is so far set up with the following functions:

Forthcoming functions are:

Trigger settings:

The engine comes from the factory with a 60-2 wheel/VR sensor on the crank and a single tooth wheel/hall sensor on the cam.

Goals:

My initial goal with this install is to overcome the limitations of Megasquirt (some of which I have reached, others not), putting me in a much better position to take the car to the next level. Also to have a good time with it, and possibly learn something useful along the way.

I purchased the un-assembled GenBoard for a few reasons: I'm doing this as much for the learning experience as for the VEMS feature-set. If I wanted a 'plug-and-play' system I would buy a Haltech or Motec. A more minor motivator was the lower price.
