Just got back from tech school in maryland...
 

got some cool stuff, i got the original ur quattro service intro book from 1982. has cool info about ignition mapping on the stock ecu and the influences of map pressure, coolant temp, and intake temp on the stock 3 ignition maps (vacuum, atmosphere, max boost) i believe by manipulating these sensors with resistors i should be able to advance the total timing by atleast 20 degrees! (with no ecu remapping)100 octane anyone???
i also got the original electrical diagrams for 4000, coupe, and ur-quattro. im going to try to get atleast some of the info on the fourm as the weeks go by.
