KAM check failure code

I just started trying to use my TWEECER RT on my new to me 90 mustang. I noticed in the data logs that theKAM data is always 1 and I know Im not that good at tuning. I checked for check engine codes and one of the codes I got was KAM check failed. I checked to see if i had any bad fuses and didnt have any. Then I looked for a wiring diagram and found that KAM power is supposed to be at pin 1. I checked for power at pin 1 with a multimeter and had 12 volts. dose this mean my eecm is faulty? Is there more I should check

code 15? Usually thats just from the presence of the tuner/chip, and not having an updated checksum. Ive never used the tweecer, so im not sure if it updates the checksum like it should. Lots of SCT, Diablo and soforth will have that same code because the tuner didnt address the checksum issue.
 
Im using BE & EA with the TWEECER RT. I would email you my tune if I knew how. Any and all sugestions on the tune would be appricated. I just did a basic tune up. Plugs, wires, cap & rotor, fuel filter and still have a miss. Im trying to get the MAF dialed in as Im using an o5 slot style in a 4" pipe thats how I found the KAM data isnt changing
