garrycol Posted May 29, 2019 Share Posted May 29, 2019 Just to help those with possible answers - is the 4.6 a Gems or Thor engine and is the crankshaft sensor you are using, the original one on the flywheel or have you put on a trigger wheel arrangement?

FridgeFreezer Posted May 29, 2019 Share Posted May 29, 2019 It's not a map you need, if you've got no VR signal something more basic is wrong. Is the board built with VR input connected through as the tach signal source? Is the sensor wired the right pins with the right polarity? Do you get anything at all when you crank it? Have you tried the trigger wheel diagnostics that're in some of the software (tooth timer IIRC)? Quote Link to comment Share on other sites More sharing options...
