ive made up a loom for running a vx ecu on bench and triple checked the wiring. all i can get it to send back is Rx'd Frame = 20, 55, 8B. does anyone have any ideas.

So you at least have something hooked up if your recieving.

I'll post some pictures tomorrow of how it's set-up and wired and maybe tidy it up a bit. It's a bit just thrown together but from what I can gather it should be wired correctly. I've had the vx ecu plugged into my vy and was able to connect to it so I think the ecu is alright.

Also details about the aldl interface your using.

[Tom.m]

It's just a usb to aldl adapter and ose enhanced flash tool. Ive been able to connect to the ecu when it was in the car tho.

have you chosen the option for a bench pcm as the bcm wont be answering?

[Tom.m]

Yea I've tryed on bench and using the settings from the thread about how to set up an on bench ecu.

Yea that's the thread which I used to wire it so I can't figure out why it's not working.
