I installed a junk yard replacement ECM in my 1 ton, it ran but had 8 injector codes P268C, P268D etc. I committed a license and did a full flash of my saved tune but still have the codes and the information display says to clean the exhaust filter.
EFILive graciously replaced the license for my failed ECM GREAT FOLKS!!
EDIT, I found reference to injector programming and it worked!! YAY!!
