Summary of change:
Hi, Car is 1994 Porsche 911 Carrera 2 (993). It has air-cooled flat-six 3.6litre engine (11.3:1 CR) and it has supercharger installed. Originally 272 hp, SC should add around 130 hp. ECU has Motronic 55pin connector and since the car has very low mileage (109 000 kms) and wires are in excellent condition, I'd like to installe PnP VEMS. Car has twin-plug cylinder heads (total of 12 plugs) and two distributors. Plan is to eliminate these and use two Bosch 2x3 coil-packs. Firing order: 1-6-2-4-3-5 I'm aware of the wasted spark configuration in twin plug system. Here's ECU pinout for that car: http://porsche-foorum.ee/album/albums/userpics/10026/Porsche%20993%20Carrera2.JPG ---- '''Primary trigger''' is VR, 60-2 standard type. No surprises here. ---- '''Secondary trigger''' is HALL sensor in the distributor. Since wasted spark, not needed. ---- '''CLT''' is NTC type ---- '''IAT''' is NTC type ---- '''Injectors''' will be most likely 500-600cc (have to be changed, stock ones are too small) High-Z together with transient 30V diode. ---- '''IAC''' valve is PWM type, 2 wires, so driven from spare IGBT or INJFET won't bring up surprises. ---- '''TPS''' is variable. ---- Under ivenstigation: *resonance flap *transmission input (most likely not needed since car has manual gearbox, not TipTronic) *Vehicle speed sensor. Also probably for TipTronic, not manual. I can add additional information about the car if needed, right now I don't now what to add more.
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.
