Trying to write with LS-Droid and it gets stuck at "Sending Request Seed"

I was able to read my bin file from my 411 PCM using LS-Droid BetaV0.2.0 on my android 6 device and OBDLink MX+. I then modified the bin in TunerPro. When trying to write the calibration only back to the PCM, it is getting suck at either "Sending Request Seed" or "Request Unlock w/key 4E29" when trying to write after the packaging stage. I have emailed LS-Droid using their feedback email, but was hoping maybe someone could help me out. I have re-looked at my bench harness wiring, been able to read multiple times, and have tried writing calibration and calibration with OS multiple times. Thanks in advance, Dave

Do you have a sufficiently strong 12 volt power supply? A one amp wall wart 12 volt power supply seems to be plenty for reading but might be insufficient for writing. I'm using a 3 amp supply.

I am using a 1 amp which was what others seem to be using...

....

+1 on the bench supply needing a fuse and separate switches for battery voltage and ignition voltage. I'm at 13.6 volts DC.

Thanks for the additional ideas. This really helps. I will have to look at my bench setup.

Hi all,

While the creator does occasionally come over here, you may want to try posting here:https://ls1tech.com/forums/pcm-diagn...-released.html
They have been getting reports of problems with the MX+, which they are working to fix.

Best of luck,
