I bought the car wit a 325i (M20) engine with a turbo, but that's sold by now, and I'm in the building of an M30 turbo engine (from a '82 745i) continuously :) The way I bought it: http://quasar.dynaweb.hu/~lezsi/bmw/original/IMG_0474.JPG In September, 2009: http://www.bmwpower.hu/gallery/albums/userpics/10444/P1100818_.jpg dyno graph: http://www.bmwpower.hu/gallery/albums/userpics/10444/lezsi-dyno-200908.jpg ---- ---- '''My own 325i old project data''' Below this point you find old project data from ~2007 of installing GenBoard onto my original M20B25 turbo engine. Original setup Car outlines as I bought it: * Engine: M20B25 (325i from ~1987) 2500cc, '''6 cyl inline''', 12 Valves, SOHC (stock, but lowered compression) [http://quasar.dynaweb.hu/~lezsi/bmw/original/PICT0004engine-bay.JPG Engine bay(huge pic)] * Fuel injection: Bosch injectors from E36 325i (part no. 0 280 150 415) maybe 190 cc/min @3.5bars. R=~16 Ohms (high impedance) * Fuel pump: Stock in-tank + stock external * '''Staging injector''': Bosch no. 0 280 170 400. It comes from the jetronic cold start inj. (not a PWM system!), maybe 113 cc/min @3 bars, R=~3 Ohms. Switched by ~half throttle pos. * Adjustable fuel pressure regulator (home made, seems working, no fuel pressure meter altough). See MembersPage/GergelyLezsak/FPR * '''Water injection'''. High pressure pump (headlight washer), Bosch cold start injector. Switched by ~half throttle pos. See MembersPage/GergelyLezsak/WaterInjection * '''Turbo''': Mitsubishi TD04-11B (it's a small one from 324d), internal wastegate with stock mech. actuator arm. * Idle control : stock solenoid, Bosch part no. 0 280 140 524. See MembersPage/GergelyLezsak/IdleControl * Intake: stock AFM with direct filter. Small air-to-air intercooler and a mech. pressure gauge. Some adjustable pressure valve as blow-off. Factory throttle pos switch (3 state; idle, between and WOT). See MembersPage/GergelyLezsak/TPS * '''stock 60-2 VR crank-trigger''' for Motronic 1.3, stock coil, mechanical distributor, 1 degree colder sparks. See MembersPage/GergelyLezsak/Trigger * inductive sensor from ignition cable (cyl. 6?) for cam position. See MembersPage/GergelyLezsak/CamPos * Coolant sensors: Two coolant temp (seems stock) at thermostat housing. See MembersPage/GergelyLezsak/WaterTemp ** 1. (one pinout) shows 120ohms @25c ** 2. (two pins) shows 2.18kohms @25c (this one sounds pretty standard temp sensor) * More sensors: There's no O2 sensor, and IAT is in AFM * Motronic 1.3 with tuned chips. * 4.27 limited slip differential (Small housing) ---- '''Project plan''' First goal : Achieve maximum power output from current mechanical design with reliability in the long run. Good driveability and fuel economy is also in sight. This is done by now. Future plan : Additional mechanical improvements possible (larger injectors, big turbo, etc.) '''Project stages''' * Stage 0 - readonly first : MembersPage/GergelyLezsak/StageZero * Stage 1 - control injection : MembersPage/GergelyLezsak/StageOne * Stage 2 - ignition control : MembersPage/GergelyLezsak/StageTwo * Stage 3 - boost control and whatever: MembersPage/GergelyLezsak/StageThree '''Design section''' * WBO2 mount : MembersPage/GergelyLezsak/WBO * TPS conversion : MembersPage/GergelyLezsak/TPS * Wiring colors, pinout, etc :[http://quasar.dynaweb.hu/~lezsi/bmw/conversion/lezsi-wiring.xls xls] '''Financial''' * MembersPage/GergelyLezsak/BuyList '''Firmware''' * Config and tables dump 20050718 - [http://quasar.dynaweb.hu/~lezsi/bmw/conversion/20050718105516.txt txt] * Have to make my own MembersPage/GergelyLezsak/FirmWare '''Megatune related''' * Bugs found - MembersPage/GergelyLezsak/MegaTune ---- '''Suggestions''' - some of them now obsolete I try to control EFI first and leave ignition to motronic. Issues with this configuration: * I have to share crank VR signal between two computers. There's a ~5V DC signal from the ECU. To share this signal, a series capacitor ("high-pass" filter) is needed so the AC is passed but DC is not. Min. value is 10uF (25V or higher recommended) - easy to mount onboard ** When two ECUs are connected, the GND easily picks up some noise so special care is needed. This is working nice now, no problems. * consider ExhaustGasTemp (will be a small appr. 10 mm drill in the exhaust before turbo) **It's stated that cast part need to be heated with gas welder (?), then simply weld it with CO welder. -It's all not suggested however if any other option possible. * get a wastedspark coilpack. Common to use Ford EDIS packs, but Opel or VW might also be an option ** 3 transformers with 2 high-voltage terminals each) ** or get 2 coilpacks if you can only get coilpacks for 4 cyl (there will be a spare) ---- Optional: Add document to category: Wiki formatting: * is Bullet list ** Bullet list subentry ...
