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
- IAT sensor: GenBoard/Manual/IntakeAirTemperature
I guess we have a lot in common: [MembersPage/GergelyLezsak]

Made my order
Cable for serial communication with the GenBoard. Use a 6.3 mm stereo jack female/male. Mount that in your dash somewhere and wire it to the serial pins on the EC18 connector. This involves building a custom serial cable to connect your computer with a male 6.3 mm plug in one end and DSUB9 female in the other end.
- notebook and MegaTune to tune the ignition map.
Assembled v3.3 controller
- ignition driver 8
- Knock and 2 EGT
- LCD and PS2 yes
- MAP onboard
- primary_trigger VR
- secondary_trigger HALL
Other items:
- LCD4x20 28.00EUR
- DSUBxx connector 1.00EUR (for LCD)
- EC36wire
- EC18wire
- 2x EGT sensor (K-type)
- 2x VEMS sticker
- IntakeAirTemp sensor
Electric fan
Will need to apply a relay, since there is no output for 30A. Several injector FETs can be driven in parallel, but this is not recommended (very easy to burn traces with misconfiguration). Check GenBoard/Manual/DigitalOut/Table and determine a free output you want to use to control the relay.
EGT
My GenBoard (serialNr=355 and 356) has two EGT cables connected to the board, at nearby locations.
You can connect two EGT sensors. MegaTune will log both mcp3208channel4 and mcp3208channel3 (raw values). However, only mcp3208channel4 is displayed on LCD page0 (mlp00).
Raw values mean that the
- real_celsius_value = egt1_offs + (raw_value * egt1_cal / 256) where typical values:
- egt1_offs=00
- egt1_cal=49 (that is decimal 73)
