Summary of change:
Hi :) Need som help setting up my VEMS Motronic-55, on my AUDI RS2 http://photo.ringo.com/116/116562328O341170106.jpg ---- Engine info: * It`s an ADU engine, 5 high output coils with built in drivers. * 720cc injectors at the moment (need power resistors), have some 1600cc (4.5ohm - don't need resistor) * custom cams and ported cylhead * JE pistons * H-beam rods * 82.5mm bore * 92.6mm stroke * Turbonetics gtk 650 * 89mm exhaust * 034 motorsport high output coil pack (5 coils) standar POS not used. ---- Q: So my high ohm 720cc injectors need power resistors? I think mine is the same as sold in the vems shop. Siemens deka 727cc@ 4bar ---- Q: I have changed my mind, and want to go for the NTC type IAT sensor. My vems is set up for the PTC type. What to do? A: Remove the additional pull-up resistor on the PCB which is mounted on top of the regular pull-up for the IAT analog input. Other people might clarify with pictures of the PCB and where you must do the work. A: I allso recived an e-mail from vems shop now: Fortunately this is easy. Remove endplate (endplate only, 4 screws).You see a small resistor near the main processor, close to board edge, parallel to board edge.An 510 Ohm (0805 size SMD) resistor is piggybacked on a 2k7 resistor.Remove the 510 ohm, and you just converted back to a normal weak pullup suitable for NTC. I guess this would be easy. ---- Q: I have some msq files for the motronic 55, but i can not understand the ignition outputs.. what is H[2]? and what does 04..00 stand for? Does this have any thing to do with the fiering order? A: The H2 is the exact firing order of the ign outputs more info at this page http://www.vems.hu/wiki/index.php?page=GenBoard%2FManual%2FDigitalOut%2FTable If the car is Audi s2 you will find some useful info in this page http://www.vems.hu/wiki/index.php?page=MembersPage%2FPeterJensen/AudiSwiring Regards Peter Q: Okay. If i understand. this should be correct when the firing order is: cyl 1-2-4-5-3 Okay. picture to come soon ---- Q: What firmware to use? can i use 1.1.23 12x12? A: Don't use 1.1.23. See this page: MembersPage/MattiasSandgren/OskarAudiSFour \\ Download 1.1.27 on the MegaTune page and go from there. \\ Q: How to upload tempsensor files? A: You have to use the tempsensor_upload script that comes with the MegaTune package to upload a firmware containing the correct temperature tables, see EasyTherm and EasyTherm/SensorTable. ---- Q: When i downloaded megasquirt, there was a PINOUT picture included.. Is there a simular picture for the Motronic 55 plug? A: Begin reading here: VemsAudiAan \ Take a look at the spreadsheet and as hinted earlier you can find a picture here: MembersPage/PeterJensen/AudiSwiring
