My project is to turbocharge a BMW E30 325i M20 engine.
Engine specs:
- cyl count=6
- main trigger= 60-2 on crank http://www.vems.hu/wiki/index.php?page=MembersPage%2FGergelyLezsak%2FTrigger
- stock internals
- T3/T4 turbo 50 A/R Compressor, 0.63 A/R Turbine .57 Trim 3" inlet stage 3 wheel
- Oil cooling on pistons http://www.e30tech.com/forum/viewtopic.php?t=5223
- Intercooler will be as big as possible
- Lime green 440 cc bosch high imp petrol injectors
I guess we have a lot in common: http://www.vems.hu/wiki/index.php?page=MembersPage%2FGergelyLezsak

I want to order pretty soon now but I still have questions about what I have to order.
This should be able to run ignition and injection without problems.
A keyboard and LCD can be used to adjust anything (including maps). However you really do want a notebook and MegaTune to tune the ignition map.
- I have a notebook right here so that's not a problem. Should I still order the LCD or is there no need for it then?
- I personally find the LCD very useful. Many things can go wrong with a custom install (cabling problem, high EGT, ego correction reaching it's limits, resulting in insufficient lambda, etc...) and the LCD and PS2 often makes it possible to diagnose problems without carrying a notebook (noone carries a notebook in the car 100% of the time). After the engine is tuned, the LCD would normally just confirm that everything is alright - if you otherwise don't believe in problems :-)
EDIS (wasted spark) coils for ignition should work. (I assume you have the connector for the EDIS coil)
Assembled v3.3 controller
- ignition driver 6+2
- Knock and EGT yes
- LCD and PS2 yes
- MAP connection offboard(electronic)
- primary_trigger VR
- secondary_trigger HALL
Other items:
- LCD $33.80
- EC36wire and EC18wire (or harness if you want less crimping)
- Bosch sensor: http://www.geocities.com/tech4tdi/pages/map.html
- IAT sensor: GenBoard/Manual/IntakeAirTemperature
I guess I can replace the last two sensors with Bosch 0 281 002 177
