DET 3 BMW e36 328

Hi Have any one have sucsees with DET 3 and Simens ms41.0 ?

I can’t get the crank tigger to work properly, I have a coulpe of times rpm signal on the DET 3 but not constant, and can’t rev passt 2700 rpm

I have scope image of crank trigger signal into the DET 3 and it is a perfekt looking hall signal, i have used the 12V pull up in the det3 and have made one for 5V 2700ohm, but no difference
