Hypertech Tuner causing dieseling or pinging
#16
Mine does the exact same on my 2010 5.4L , tech told me to use higher octane but that's all they could do since the programmer was for my old truck but I changed the software for it to be compatible with my current truck. Though I don't wana be having to put in 93 octane every fill up on a 87 tune...

I was just able to verify that the dieseling sound I was hearing was coming from the tune's transmission enhancements, not the timing.
After the tune was modified to reduce the transmission changes, the sound went away completely. I'm now working with them to adjust the tune to it's potential.

They really should, bought it a few years back because they had a great deal going on at the time. It was orginally for my 06' F250 with a 5.4L, ended up to the point where even on stock my engine would ping constantly. I thought with new software it wouldnt repeat its past history with my current truck, guess I was wrong. I' am going to take it off and wait until I have some money to buy an Edge or SCT programmer.
