Im in desperate need of help, when installing my DSP5 switch I accidentally put the pins in 45 and 54 instead of 46 and 54. I cycled the switch and it started throwing a bunch of codes. Now my ECM is not communicating properly and a shop says its fried. By doing this did I fry my ECM or was it something on the tune? I just dont want to put in a new ECM and go to tune it and fry it again. As I was going through codes I noticed injector 5 balance rate was over a volt off the others and over a volt different than the last time i checked balance rates. I looked up Pin 45 to see where it goes and sure enough it is to injector 5. May I have also damaged my #5 injector?

If you reload a stock tune, you may have your answer.

Also log your dsp voltage, as long as it is showing 5 values that make sense, you should be ok with another ecm.
