    Default Need help ASAP. $0101 no data recieved error

    Alrite I'm new to efi so I'm learning as I go. But here is my problem. I read stock tune and converted to to dsp os using v7.5 now when trying to flash in my dsp5 tune on v8 I'm getting a no data recieved error. Truck will not even attemp to start. So I tried flashing stock tune back in on v7.5 and am getting no connection error. Any help is greatly appreciated been trying to get this thing flashed for 3 days now.

    Sounds like maybe after the ECM was read it did not reset properly, just try pulling the ECM fuse for 30 seconds, or, pull the battery cable off for 30 seconds.
    After that see if the truck runs, if all good then try your reflash. You can't damage an ECM just by reading it, so it should be fine.

    When you went to reflash the truck the first time, did the flash process start, get part way through? Or did it right away say no data received?

    After I read stock tune I converted it to dsp os then saved that file. Once I saved it I performed full flash with that file and it went all the way through now when I try to flash the file in with my dsp5 tunes I am getting a no data recieved error. Should I not have flashed it after converting os to dsp format?

    Oh, that is a different story (and not a good one).
    What engine is this? LB7, LLY or LBZ?

    Lbz. I believe the ECM is fried or dead because it will not communicate now

    Unfortunately it does seem like that might be the case. I don't hear of them being bricked very often, maybe some of the other Diesel guys could chime in as to what to try.

    I am sure that your no data received is not a dead ecm, I have not seen any issues with LBZ or LMM with that code.

    Do you have any aftermarket radio, i-pod adapters, nav units ?

    If you can, I can put it on my bench harness and test it for you, if you would like please contact me.

    Thanks
