Need help

[jaydog]

I am trying to reflash my 2008 LMM for the first time. When I try to reflash I get a reflash failed, aborting.....See the screen snap shoot below. What am I doing wrong? I have the key in the on position and I do not have anyting on like radio, dome light, etc....

[jaydog]

The screen shot is kind of hard to read so here is the text from the EFI Live programming box when I try to reflash the ECM. I also just though of one other thing. My boost and pyro guages come on when I turn the key to the on position. I have no way to turn them off other than disconnect the power lead. Could this cause a problem?

Hi Jaydog,

What version of the software are you using?, it looks pretty recent from the screen shot.

My boost and pyro guages come on when I turn the key to the on position. I have no way to turn them off other than disconnect the power lead. Could this cause a problem?

If those gauges get their data via the CAN data bus, then yes they will cause a problem during flashing.
Try disconnecting power to them to see if that resolves the problem.

I will try that tonight after work.

Well, I disconnected the power to my guages and that was not it. I can read the ECM fine. But no matter what tune I try to upload back to it I get the same thing as stated above (reflash failed, aborting.....) Even when I try to upload the stock tune that I just downloaded from it.

Does anyone have any other ideas? My truck is sitting dead in the garage until I get this figured out. I just installed my 4" MBRP turbo back exhaust and EGR block plate and I do not want to start it until I get the right tune programmed in to block all the DPF and EGR codes. I have sent EFI Live support this information and have not heard back yet. Hopefully I can get this thing figured out soon. It sucks having a new D-Max sitting in the garage that I can not drive. Especially with the new exhaust on that I am excited to hear run and see what kind of power it has now.

Do you have the latest firmware in the handheld?

[Tordne]

He is going to try again soon with the latest update (Build 78) and let us know.

[jaydog]

Do you have the latest firmware in the handheld?

How do you update the firmware in the handheld? I assume you would update it through the laptop? I have not had much time to read the manual or any tutorials yet. Thanks for your guys help.
