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

Engine specs:

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


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.


LPG section

I wil be running LPG with a Vaporised Sequential Injection System. http://www.prins-lpg.com/en/products/vsi/index.html Have you looked at any liquid injection systems? - MembersPage/RichardBarrington

Stage one plans:

Future problems:

- I don't know customers prices, not my department :) You can send them an e-mail if you want to know. -Did that, no answer :( They might to be busy with larger volume OEM deals... don't take it too personally. Pricing compared well to aftermarket EFI stuff last time I checked, but best to ask for specific prices and supply application information (make it easy for them!). With globally rising petrol prices, we might have more luck approaching this as an "official" VEMS initiative. I've talked to Prins before, so why don't we make an LPG page and sort these issues out? - MembersPage/RichardBarrington

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