Daz were you able to write using the bench harness without an immo defeat?

You can't write it without immo defeat, as it will reject security access.

What PRJ said. I can connect, but not write as security access blocks it. With the immo-off, I can read and write without an issue, but at that point I'd rather BDM as it takes half the time. The PITA is opening those things. Title: Re: Communicating with a MED9.1 and MED 9.5 on the bench Post by: airtite on November 12, 2013, 02:59:13 AM If it's on the bench then BDM it.

Thanks thats what I thought, I was speaking to a tuner yesterday who said they have ordered a bench harness that allows them to write and I was like hmmm ok. |
