Cant get ignition working,
Det3 shows rpm but wont sync . Shows Syncing-syncronized-no sync and repeats again

Pin 9 to b135-1>>>>>vr sensor --------------------------Pin 5 bipolar to b135-1 ecu side.
ignition options: 6wheel subaru trigger
couldnt start my car
scope shows nothing

so changed over Pin9 to b135-8>>>>>vr sensor.................Pin5 bipolar b135-8 ecu side
could start my car shows rpm but wont sync repeating loop al the time if increasing rpm about 10 secs shows synced after that again no sync and repeats.
scope shows some data getting signal

Cables about 5cm long.Checked all connections etc.
with multitooth trigger shows synced but rpm incorrect etc..


Tryed 1.25 1.30 versions of det3 firmware .


Any ideas?
