After using chip for a few days decided to try some other tunes.
With truck off I removed chip and switch.
Inserted chip into programmer.
Connected usb cable.
Connected power supply.
opened software.
selected new tunes
verify chip is in pos 1.
verify program is in 6-position chip.
clicked on write to chip, goes through loading tunes then click ok to erase chip and i get an error"The module was not either placed in pos 1 or is not properrly formatted as a multi position module".

check diagnostics and multi authority bit =FF

tried reseating chip no change....

Thanks Mike
