Summary of change:
Subpage of MembersPage/MarcellGal/PowerAndTraction, the implementation of PlugAndPlayMotronic on Audi 200 quattro 20V turbo The differences between * AAN * 3B * custom harness based on Econoseal-36 + Econoseal-18 ** or small adapter from EC-xx to AAN or 3B is trivial. If one can make either, he can make any other work. However, there are a few details about the car that would be nice to have in the PNP install. Anyone aware how the motronic55 ECU notifies the * fuel-consumption display * and the boost data display in the Audi 100/200/S4 ? Likely the same in the 80/90 chassis. MembersPage/DaveHartnell might know after 2007-03-12, when his factory manual set with extensive wiring info should arrive. - The manual shows that a potentiometer<variable resistor> described as a fuel consumption sensor in the Fuel distribution head/flow meter measures the position of the plate, just like a TPS. IT's a 3 wire sensor that connects directly to the gauge for its power, ground and signal The gauge cluster has some adjustment for fuel consumption trim between 0 and 15% is described in the manual using some switches or a resistor on the cluster itself. I can take measurements of the Sensor with the throttle plate closed, at idle and at WOT if they are useful. '''Speculation and experience''' MembersPage/EmilLarsson knows the bmw's do some strange calcs inside cluster, for fuel consumption: the gauge starts moving when hooking up tachometer. MembersPage/SamiKorhonen : some guy used 0-5V signal what his old KE-jetronics MAF gave to his computer. In fact the tach signal, and a 0..5V signal should be all that is needed. We just have to find out where the 0..5V signal connects, if it's MAF or MAP signal, and if it works like we think ;-) ---- '''CLT and MAT strange measurement values''' on an Audi AAN (20VT) engine * we measure 116kOhm (and 1.6MOhm with other polarity, though voltage is 0mV) between GND and CLT (motronic pin 45) ** weird, as we expected < 20kOhm between GND and CLT (also between GND and MAT, that is motronic pin 44) Admittedly, we don't know for sure that CLT and MAT were operating on this engine. The factory ECU often ran awfully rich. It would be good to know, which is the CLT sensor for the ECU * water manifold sensor with 2 blade connectors * water manifold, other sensor * coolant radiator bottom => this switches fan, not related to ECU * rear (or front?) end of the cylinder head ? * we also see a (likely temp) sensor (with 2pin AMP connector) in a thick (appr 30mm) tube, probably hot coolant for cabin heating system
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.
