My project is to turbocharge a BMW M20 engine.

At first I want to know more about VEMS before buying it so I have all the things I need and don't get a delay later on for not haveing everything.

I'm located in the Netherlands so if there are more people here I can talk to in dutch I would certainly appreciate it. Let me know!!

I guess we have a lot in common: http://www.vems.hu/wiki/index.php?page=MembersPage%2FGergelyLezsak


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.

Q: Why not run the MAP sensor that comes with the Genboard? The internal mounting is perfect and secure.
Q: Do you need a stock IAT sensor? You can buy a 1 Euro NTC resistor, has worked great on many cars as intake air temperature sensors (faster than stock Bosch). More info here: GenBoard/Manual/IntakeAirTemperature

Q: What do I need more?

A: You can distribute spark through the stock distributor, which on your engine is mounted in front, on the head of the engine. You will eventually need an ignition amplifier with lots of boost if running this setup, single coil and distributor.
VEMS Genboard can control separate coils for each cylinder, if you provide the correct trigger for it. 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!).

Q: How is a laptop connected?

A: This question is answered in the manual, please read it fully: [GenBoard Version User's Manual]
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.

Q: Can I load two maps and switch between the two while driving without a laptop? One daily map and one track map??

A: No you can't with the current firmware. Why would you want two different maps? The only reason is if you use two different fuels and need different VE maps and ignition advance. Of course with boost control you could have a lower setting if you choose to experiment with the boost controller code. At the moment that is easier with just physically manipulating the wastegate spring pre-load.

I have the same 60-2 wheel http://www.vems.hu/wiki/index.php?page=MembersPage%2FGergelyLezsak%2FTrigger
