Summary of change:
Hallo, i was amazed as i saw today that there is a PNP Motronic VEMS. The question is now how PNP is it and what must i change. * be warned that there are many different motronic pinouts. You have to identify '''and verify yours''' ** if you correctly identified and verified, it should be rather simple to get the car running if it's a tested setup *** As far as i know it is the same as the Audi ABY engine and the later AAN engine with the Hallsensor at the Camshaft pulley. I suppose that this setup is known (please confirm). If it is so, then this means what with the VEMS i can control and setup right away Ignition,injection and boost control? ** if the setup is yet untested, one has to be even more very careful with the pinout verification and documenting it. This is not recommended to someone who would not dare to make a native econoseal install * using a factory harness can help a bit, if it's in good condition. But any problem can cause a lot of headache, and if there are problem, finding and fixing it is often more difficult than with a self-made harness (or a new documented harness) **Factory harness is OK right now. The car is original and running every day. * getting the car running is the start of the fun and risks. ** One has to be '''very careful with tuning''', and be prepared to stop and go back to the measurements and debugging, should the slightest suspicion arise. Tuning requires knowledge and experience. It is highly recommended to get someone experienced help, at least for the first few times. ** one has to plan any modification very carefully. It is very important not to ruin something important (in harness, ground, flyback, fuses, or ... config). ***Of couerse. My main consern is the instalation and Set-Up of the VEMS on my car. If the sensors are recognized and work right after the VEMS is plugged (and with the initial - Basic maps) with Megatune. We cannot use debugger things and write scripts for softaware alternations. After that i can get someone to tune on megatune. I am not very electronically inclined so my questions are dumb: I plug the VEMS PNP-Motronic to the harness, istall and connect and verify and calibrate the Wide band and the EGT. Is the car now ready for the Tune? The VEMS comes out of the box with support for the Ignition, injection and Boost control without further mod to the Sensors or the cables of the Car? Is it possible to find for starters a full runing program for the ADU engine, and from that point modify it further? * we have full running dumps for ADU engine (and 3B, which seems to need slightly higher pulsewidths) but even from a conservative one, one has to be very careful (add more fuel, take away some ignadv, verify lambda, EGT and sound, etc...) and tune almost like it was an unknown engine. Such configs help to get the car started though Hi, i am thinking of Using the VEMS v3.x on my currently Stock Audi RS2. It has from the Factory an I5 2.2. liter Turbocharged engine (Engine Code-ADU). The stock ECU system is a Bosch Motronic. For the future i am preparing a strong bottom end and big turbo. The car is an everyday car and want it to have a cultivated ride (when i am cruising with it or in the City). I want the Climate Control (Air Condition), Auto Check (it has also Trip Computer but i think it will not work with the VEMS). I would like to make the convertion this way so i must only change the less possible stuff to run on Vems (and also easy to go back to the Motronic system if the car will be sold). ----------------------------------------------------------- MembersPage/Billman/Failsafe MembersPage/Billman/VEMSOptions MembersPage/Billman/PlugNPlay MembersPage/Billman/BuyingList Thanks a lot Vasilis
