I've been looking around for a while for a DIY ECU and after reading up on MS i found VEMS and just looking at them both from a bachelor's in electronics point of view, the VEMS used technology is just that much more modern (smd, descent connectors instead of DB type, etc...)
The ECU will have to run a standard stripped 1.8 zetec using GSX-R throttle bodies and all standard sensors(except for the lambda) in closed loop lambda as I have to meet emissions in Belgium. I also would like to run it in wasted spark sequencial injection mode.
How well does the VEMS handle dwell timing for the ignition? Or can i better use a EDIS4?
- MembersPage/PhatBob Don't run an EDIS-4 as we've got litteraly hundreds of installs runing the Ford EDIS coil pack from the IGBTs. We have configurable dwell time with scaled low voltage addition.
My shopping list is currently as follows, but it would be nice if someone could confirm.
1x Genboard v3.3
3x clamping plate
1x Alubos EC frontplate
1x Alubos endplate
1x alubos gasket
1x alubos1600
1x econoseal18-PCB
1x econoseal36-PCB
1x econoseal18-Harness
1x econoseal36-Harness
1x Idle stepper motor driver (is this needed?)
- MembersPage/PhatBob Its not essential, but it provides another 4 12v 1A output drivers.
1x Ignition driver insulator sheet
8x injector/WBO2 heater driver
1x power flyback (is this the best option?)
- MembersPage/PhatBob The best option is the 30V transient voltage suppression diode.
- MembersPage/PhatBob 250kpa will be adiquate for you if you're running normally aspirated.
1x Wideband connector
1x Wideband O2 sensor
All this is supposed to run in a SSC [Stylus] by february 2008
We've got one running on that very same car:

Check se7ensport's other emails for a pretty good walk-through of what he experienced going through the install.
Update may-2008
Received the Parts and will start assembly soon. (looking good already)
also the date was really optimistic and if it runs by september I would be happy
Finding the necessary info for assembly isn't easy on here, so I've made a list that helps:
