I will tell you why its NOT OK

The DME uses the lambda and o2 sensor to calculate fuel trims over some period of time. If you trick the DME with a flat value, you are going to have bad trims. Bad trims means bad A/F ratio. Thats not a problem you want to have for a DP. Its batter to leave the sensor alone and mask the code.

My Indy looked into it and discovered that the DPFix was remaining on all the time. They hooked it up to a switched circuit so that it is fully powered off with the engine.

After doing that, no more codes... and it continues to work fine... readiness goes OK too.

Did you remove it?

No there was no need to remove it.

I installed a multi tap switch so that I can turn it on or off as needed.

I am trying to get my hands on a DP fix for my n54. Need to pass my emission test, which is becoming a pain. Any help?
