Summary of change:
'''Golf II 1.8 16V GTI''' (motorcode KR 139 Le) * want to convert to gasoline-LPG * currently NA, but later turbo Assembled ECU features: * Flyback 30V flyback * ignition driver 6+2 * MAP connection 300kPa onboard (6/4mm pneumatic) * '''primary_trigger HALL''' * '''secondary_trigger HALL''' * 1-wire interface no * Knock and EGT yes * LCD connection yes * PS2 connection yes * mounting-style screws ---- '''Injectors''' * Bosch 0280 150 126 (12V / '''3 ohm''' = 4 A). (215 cc/min) injector - pins: * injD EC36pin20 cyl1 * injC EC36pin8 cyl3 * injB EC36pin19 cyl4 * injA EC36pin7 cyl2 h[0]=01 02 04 08 10 20 40 80 ---- '''Ignition out''' Firind order 1 3 4 2 * Ignition transformer: Ford spark 88SF-12029-A1A 12V ** 1 ohm Is this a 2x2 wasted spark coilpack ? 10A fuse each: * EC36pin34 * EC36pin36 We use channel2,3 instead of channel0,1 (pin33,35) because that is also available in the controller with 2+6 ignition option (so easier to get a spare). ignchmax=03 h[1]=00 2D 1E 0F 00 00 00 00 h[2]=20 30 20 30 20 30 20 30 ---- '''Idle air''' * IAC:Bosch 2 kivezetéses 2.6 ohm '''4.6 A''' * use an injector output, eg. injH ** maybe you need to connect some fuel injectors in batch * connect a BY399 diode: cathode (marked with stripe) to +supply; anode to - (switched to ground by ECU) ---- '''Sensors''' * TPS: Bosch 0280 022 001 (from Opel Calibra) az 1 és a 3 as érintkezö; közt az ellenállás 3,15 kohm. * "temp sensor": original VW (885C @ 30C ... a bit too low) ** is it CLT or MAT ? coolant or air ? No knock sensor. 1GT101 HALL sensor from WebShop can be supplied from 5V or 12V. See datasheet ---- '''Oxygen sensor''' * Bosch 0 281 004 042/043 (5 wires) ** is this good ? ---- '''LPG injector''' * BRC 5V (4 pieces used, 1 for each cyl) * Tipp: 09SQ990200026 4997/1. * 3ohm 6.8 ohm 50w power resistors will be used ---- '''Switch between gasoline and LPG''' A 2-circuit switch would work * 1 circuit switches relays * the other pulls an ECU input to gound to notify table-change ** See EC18pin12,6,16 mcp3208 analog inputs in WebShop ECU specs, all are available in your case 4 relay switches node30 (through 10A fuse) to either * gasoline injectors +supply 87a * LPG injectors +supply 87 Obviously, get the engine running WELL on gasoline first. ---- '''Launch control''' Just like for the gasoline switch, pull an mcp3208 analog input to ground. See EC18pin12,6,16 mcp3208 analog inputs in WebShop ECU specs, all are available in your case. Measure if they are pulled up to +5V internally * mcp3208ch6 and mcp3208ch7 inputs might be pulled to +5V via 2k7 internally depending on how you requested. If so, no need for external pullup resistor in the harness ** in any case, be very careful: pull to +5V gently, or to ground with a switch. These inputs are not protected agains +12V ! +12V on mcp3208 input would ruin the controller. ---- wiring http://www.vems.hu/files/GolfGtiLpg/bekotes.xls schematic http://www.vems.hu/files/GolfGtiLpg/bekotesi%20rajz.jpg
