IMPORTANT: enter the case-INsensitive alphabetic (no numbers) code AND WRITE SOME SHORT summary of changes (below) if you are saving changes. (not required for previewing changes). Wiki-spamming is not tolerated, will be removed, so it does NOT even show up in history. Spammers go away now. Visit Preferences to set your user name Summary of change: A motronic55 install might save some time making a harness, but you must always verify the harness reasonably carefully. This involves * measurement of all used pins ** mostly DVM ohm-mode ** sometimes voltage mode * visual inspection ** the injector part of the harness receives much heat. Insulation might be worn. It's better to fix ASAP, than to risk engine damage. ---- '''Documents and files to use''' * [http://www.vems.hu/download/v3/Motronic55/ motronic-AAN-ECxx.xls pinout spreadsheet] ** this is the most important docs, so you know pinout and function mapping. In MegaTune you will see names like EC36pin10 while you have it wired to some motronic pin. '''While you do the measurements, write the measured value and the pin you used, and any notes you think appropriate''' * firmware 1.1.23.zip from [http://www.vems.hu/download/v3/firmware/ here] * MegaTune (1.1.12 or later) ** latest v3gui.exe also [http://www.vems.hu/download/v3gui/ available here], useful for firmware upgrade and config dump. Use the latest (currently 2007-08-03) * temperature calibration tables from EasyTherm ** coolant: NTC type 1900_256 or 2063_256 is a very good starting point ** MAT: AUDI uses NOT NTC but special PTC type, ptc_260_425 is a good starting point *** EasyTherm page has the ptc files: download [http://www.vems.hu/files/Firmware/release/ntc_ptc_hexpatch.zip ptc files], unzip and copy the PTC files (or at least PTC/airXfactorptc_aref260_425.hex that you need) to your disk where v3gui can use it (V3GUI-release/ntc directory might be the best place) * AAN starting [http://www.vems.hu/files/MembersPage/MarcellGal/Audi/etc/mcd_mct_hl_AAN_runsfine.txt config and tables] ** note that better tuned fuel and ignition was made for 3B engine (and successfully applied to AAN as well), see MembersPage/MarcellGal/PowerAndTraction * normally you have some preference at the time of order, like MembersPage/TeppoKalske (page bottom). Also consider that the crew who built and tested your device might have updated it! ---- '''Sensor measurements''' Measure sensor resistance against AANpin30. * ... Ohm between 44 and 30 (MAT) * ... Ohm between 45 and 30 (CLT) Take note of the temperature. If the engine is stopped for hours, the coolant and MAT will be close to ambient temperature. ---- '''Injector and idle-air output measurements''' Measure injector and idle air pins against AANpin37 (that is the flyback pin, same function as EC36pin23 in standard VEMS docs) * inj cyl1 * inj cyl2 * inj cyl4 * inj cyl5 * inj cyl3 ---- '''Grounds''' Measure that grounds are strongly (max 0.1 Ohm) connected inside the VEMS ECU. * AANpin10 * AANpin19 * AANpin24 * AANpin30 sensor ground * AANpin48 trigger ground You can measure that most are connected in the harness, but at least AANpin30 (sensor ground) and AANpin48 trigger ground are likely not connected. Measure that all the above grounds are connected inside the ECU. ---- '''Trigger''' This step assumes you successfully made all the above steps. This needs ignition on. The secondary trigger crankhome-VR is already reversed. Resistance=... ---- '''Trigger''' Measure trigger resistance against AANpin48. * 882... Ohm between 49 and 48 (135 cranktooth-VR primary trigger) * 886... Ohm between 47 and 48 (crankhome-VR secondary trigger) '''HALL signal''' * ... V between ... and 30 (this needs ECU plugged in and ignition on) ** changes between 0 and 4..5V as the engine rotates This step assumes you successfully made all the above steps. ---- '''WBO2 on SSC4 male standard (not used any longer)''', SSC5 is default now *pin1 nernst,WBO2 pin 1 *pin2 pump(-),WBO2 pin 5 *pin3 pump(+),WBO2 pin 6 *pin4 heater(-),WBO2 pin 4 * '''Remember that WBO2 pin 3 must get heater+ from a 5A fuse from +12V supply wire !''' The WBO2 heater+ does not come from the ECU (only the WBO2 heater-) '''WBO2 Rcal''' Resistance between pin2 and pin6 of the 6pin WBO2 connector: 103 Ohm http://www.vems.hu/files/MembersPage/TormasiAudiAAN/ has some msq files. The ignition output channels are suspicios. channel 4 assigned to 2 cylinders. Az autó tökéletesen mûködik, ALS, LAUNCH CONTROL beállítva, és egy konzervatív utcai programra hangolva. üdv: Kovács Ákos -- Try 1.1.23 instead of 1.1.24 but obviously the recommended config was not uploaded (or changed for the bad): * the tables are very different, not sure if that is intentional * there are several severe config errors as well: Terminal log file Date: 2007.08.16. - 11:07:42
