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.

- 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 [repair/upgrade] if you cannot or do not want to fix it yourself.
- VemsTune: See [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.

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?

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).
- The method of debugging is to reproduce the setup (or parts of it) or review .vemscfg according to the detailed wiring.
- 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.

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? Mabye the drivers arent mounted as it was set up for 4 cylinders?
