Summary of change:
I have the VEMS ignition, fuel pump and coolant fan setup with 9 fuses. fuel pump relay ground is connected to EC36/17 (injector channel) and Coolant fan at EC36/6 (injector channel). None of these relays actuate in test mode. '''Reply from support:''' * You can '''configure for MISC1 or MISC2 output''', and change the inverted flag (in outputs dialog) back and forth to test. ** (note: use a "diagonal matrix in injector output groups dialog, so each group contains exactly one injector FET output). ** If there are damaged injector channels, removing or replacing the p259 will NOT fix the problem. ** See [https://shop.vems.hu/catalog/repair-upgrade-p-103.html repair/upgrade] if you cannot or do not want to fix it yourself. ** VemsTune: See [https://vems.hu/vt/ vt] '''Even with newest VT, for new (round or ECU) firmware compatibility, please: Preferences / Update ini files from web.''' - confirm that you've done Update ini files from web. '''Reply from Per:''' I did check that the actual injectors worked, and they did. I used the other outputs dialog to test fuel pump and coolant fan, where I assigned the channels and had a test button? The ini files and firmware are up to date, i can post the versions later. '''Update from Per:''' VemsTune 1.5.57 - FW 1.2.38 - "no new ini files found" when updating from the web. Still havent found the issue here. Re-checked that Pin 6/17 is connected to relays ground pin, but does not actuate relays. Suggestions to other more suited channels? '''Reply from support:''' ((MembersPage/PerH/VemsWiring)) - detailed wiring is necessary to be able to help. * (from the response last month, still neglected, apparently preventing effective help): '''no wiring details provided''' ** The method of debugging is to reproduce the setup (or parts of it) or review '''.vemscfg''' according to the '''detailed wiring'''. *** This is impossible if one or the other is not provided (or apparently neither, in this case). * Important: Detail your wiring grounding. See GenBoard/Manual/GroundConnections ** Device will get damaged if grounding is not good. '''Update from Per:''' * I have complete detailed wiring in a google sheets page that i provided in the main page - it has all wiring of the car, and the VEMS Specifically in the "ECU System" tab. The connections between "ECU system" and other sheets are the leftmost column of each sheet - i will update ((MembersPage/PerH/VemsWiring)) with use of this sheet. * I'll update with .vemscfg as well, but remember that this still i incomplete - i havent even turned the engine over yet and have only verified inputs and outputs. * The ground- wiring configuration isn't detailed in the google sheet, but it's made like prescribed in the user guide regarding cable lengths. '''Update from Per:''' I gave up on the injector outputs that didn't wok for some reason and connected the relays to Stepper C and D. Inverted offcourse. This works fine, question is why the injector channels didn't work? * Maybe the drivers arent mounted as it was set up for 4 cylinders? ** No. '''Always 8 injector drivers are mounted, regardless of the number of ignition IGBT-s''' ** Plus 1 or 2 LSU4 heater FETs (depending on single wideband, or dual wideband). ** Perhaps the outputs are damaged. Most often the damaged FET (or IGBT) outputs are short circuit to GND. But if the injector FETdriver is damaged (that is uncommon, but not impossible), it might be that some injectors are not activated for some reason. ** misconfiguration happens more often. The injgroups can be setup to activate more than 1 (any injector outputs, up to all 8), or no injector output at all. "Diagonal" injgroup table is recommended for hardware tests (misunderstanding is less likely that way) This was the order, '''v3 serial number is 10418.''' https://photos.app.goo.gl/WZB3iErdmVmpauTG6
