Summary of change:
My project car is a BMW E30 from 1984. In 1996 the car had been rebuilt and got a 325i engine with a TD04 turbo. http://quasar.dynaweb.hu/~lezsi/bmw/original/IMG_0474.JPG Since then it has got some major improvements like limited slip differential, intercooler, water injection, etc. Engine management remained Motronic 1.3 Now it suffers from the lack of engine control, sometimes knocking sometimes coughing, that's why I'm here, and want to see a GenBoard inside! :) ---- '''Current setup''' These are engine outlines (and details) before changing anything: * Engine: M20B25 (325i from ~1987), 6 cyl inline, 12 Valves, SOHC (stock, but lowered compression) * Ignition: Trigger from Motronic 1.3, stock coil, mechanical distributor (guess it has no mech. advance), stock sparks * Fuel injection: Bosch injectors from E36 325i (part no. 0 280 150 415) maybe 190 cc/min @3.5bars. R=~16 Ohms * 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. Actually switched by ~half throttle pos. * Adjustable fuel pressure regulator (home made, seems working, no fuel pressure meter altough) * Water injection. High pressure pump (headlight washer), unknown injector. Actually switched by ~half throttle pos. * Turbo: Mitsubishi TD04-11B (it's a small one from 324d), internal wastegate with stock (direct pressure controlled) mech. actuator arm * Idle control : stock solenoid, Bosch part no. 0 280 140 524 * Intake: guess it's stock AFM with direct filter. Factory throttle pos switch (3 state; idle, between and WOT) * Sensors 1: stock 60-2 crank trigger wheel with VR, some inductive sensor from ignition cable (cyl. 1?) for cam position * Sensors 2: Two coolant temp (seems stock) at thermostat housing. 1. (one pinout) shows 120ohms @25c, 2. (two pins) shows 2.18kohms @25c * Sensors 3: There's no O2 sensor, and there's no IAT (excepting the one may be included in AFM housing -which has to go either) ----
Optional: Add document to category:
Wiki formatting: * is Bullet list ** Bullet list subentry ... '''Bold''', ---- is horizontal ruler, <code> preformatted text... </code> See wiki editing HELP for tables and other formatting tips and tricks.
