I have a 2005 tahoe that I installed a duramax diesel into. the past few years I have been able to get it inspected but its a hassle. since the computer is not a gas computer to match the truck, the state computer has an issue to complete the inspection for the OBDII tests. I have the original pcm for the truck, and tried having it on the serial data line, this works, however the ready statuses for many of the tests are not ready, and will never become ready driving the truck,
is there a way with efi to instruct the computer to report these statuses as ready?

I do not want to pay for a license to rewrite this pcm and if it does not work, have a wasted purchase, for a pcm that would never be used, so is there any one out here that has or can disable all test and mil test to see if this will allow the ready status be all clear and ready with out driving?
