Afternoon, Im helping a mate set up V4 scan and having trouble connecting, Its a VT supercharged V6 in a landcruiser comp truck. The memcal has been modified to not use the BCM in the conversion. The cable he purchased from ALDLcable.com for the OBD1 interface and downloaded the V4 evaluation software from the EFIlive website. Its showing inteface connected ok but not detecting any chatter. We have selected GMH-VT6 as the vehicle. We have hooked up a Snap On scan tool to see if there is a problem with the converted harness and everything works fine, We are able to see all sensor's cycling fine. Can anyone see why I cannot get any chatter from the ECM?
Below I have pasted the data when trying to connect,
56:43.593: Start macro: Clear diagnostic trouble codes: CLRDTC
56:43.609: Synchronising ALDL communications...
56:43.609: Waiting for heartbeat: $08,$55,$A3
