My project is to turbocharge a BMW E30 325i M20 engine.

Engine specs:

read: original MegaSquirt documentation besides VEMS manual, since MegaSquirt is basically the same.

Q: Which parts do I need to get full control of injection and spark?

Assembled v3.3 controller

I want to use a bosch map/temp sensor I'll get the number later on. Pro's con's mapsensor

IAT sensor: GenBoard/Manual/IntakeAirTemperature


Spark control

With your stock 60-2 wheel you can control a wasted spark coilpack directly with VEMS without any additional triggers. You can borrow a coilpack for a 6 cylinder car from an EDIS6 equipped car, like a Ford V6 (You don't need the EDIS module itself, just the coilpack!).

Laptop connection: Basically you use the serial port on the computer, and the corresponding port on the Genboard is either through the smaller EC18 connector or from a pin header inside on the board, which is usually routed to an end-plate in the form of a regular DB9 (standard serial RS323) connector.

VEMS GenBoard/VerThree (v3.x, like v3.3) has 8 output channels that are capable to drive low impendence injectors.
