Customized firmware updated to account (BMW std. Bosch double winding idle valve drive) code.
- Engine specs: MembersPage/BengtR
- Problem is that engine does not start.
- Could someone verify my trigger and cranking fuelling settings ?
- trigger specs are at ... ?
- Check that ignition channels are mapped according to sequence
- and don't forget h[2] goes from right to left
- do you get valid RPM?
- do you get wheel-error ? W.. on LCD 2nd page (Man mlp01 mll)
- how did you find the base timing ?
- For first glance, config seems reasonable, except the offending output channels that are not disabled and colliding. There are several types of not starting. I assume that it does not revv higher than the 399 RPM cranking threshold. So if the basic wiring and config is OK, than cwl, cwh needs to be adjusted (more fuel) - or alternate changed to enable simultaneous injector firing during cranking. Can you smell fuel in the exhaust ?
- I suggest to check power (maybe some fuse is broken?)
- fuel pump
- fuel injectors. With ECM off, unplug the injectors so you can measure in the connector. You can disable the fuel pump (it's a good idea anyway to have a physical switch; but it's disabled anyway after the configured 5 seconds of inactivity). You can try to fire the injectors with mdh.0 commands, eg. mdhd0 (h[0] element 5 on) and mdh50 (h[0] element 5 off) and measure with DVM (voltage that would go on the injector: should be 12V when on, <0.8V when off). See GenBoard/Manual/DigitalOut
- ignition coil (there is only one coil, right?). Remove the coil if you play with mdh.2 commands (commands that end in 2 refer to the ignition channels), you don't want to blow the coil fuse (or fry the coil!)
- check GND5, never hurts
- check Flyback as well, for each injector channels !
