Labels and ATDC advance

Post by steve100 »

I don't seem to be able to configure a negative figure in an advance cell to set an After TDC 'advance'. particularly in the 0,0 'cranking' cell - is this intentional?

Also is it worth putting units labels in the configurator map pages to show kPa for MAP or % open for TPA as appropriate depending on whether MAP or TPA is selected.

Thanks
Steve

I believe the advance range is 0 -> 59 degrees, so no it doesn't appear you can have -ve advance. One way though would be to adjust the relative position of the trigger wheel missing tooth and VR sensor, to give a fixed offset from the map values, but bear in mind this will also move the 'limp-home' 10degBTDC timing.
