so i have just finished my k24a harness and proceed to starting it im using emu black v3 .068 when starting i noticed that the rpm when cranking shoot almost to 4000 or 12000 rpm whic is not possible im using a sheided core for the trigger sensors and i dont know why does it jumps arround andd wont sync ihave tried aaall the thereseholld setting , all thee pull up and then pull down setting but still no luck i have even tried to change it to my other car and the ecu was working like normal
heres the log and the map
does any one have a running k24a rbb base map that want to share to me would be really appreciated want to take alook at the trigger settings
Hi so the twisted shield core is not grounded but it does not make any changes but any way i have resolved it my own bit weird but heres the previous situation
in emu black there is 3 ground sensor pinout so i have set it up like this
Pin b29 is for trigger grounds and knock sensor ground
b38 is sensor ground for the tps and engine side sensor
b39 is for Pedal sensor
.
i tried to move only the crank sensor ground to the from b29 to b39 pin an whoala the trugger status eror from unknown suddenly its all like normal
its is really strange
isnt all sensor ground would end up sharing the same path or ???
Shield grounding is a finnicky thing that no one pays attention to. This is why I usually ask about it early. It’s the very first thing I plan for in all harnesses. Period.
A shield’s ground is not the same thing as power ground. I do some other things to my shield grounds too, but I don’t want to muddy the waters any further here.
Good job on finding a solution and thanks for letting us know!!
