So I spoke with Shawn at IP&D the other day and got some weird info. All of these soft codes that we are throwing from our deletes and deleting with the Edge on startup are actually getting stored in the ECM. After it happens about 3 times or so, the ECM goes into a protection mode and detunes the engine to roughly 10% or so. The only way he said you could clear the codes is with a Snapon Modis or a solaris or one of the high-end diagnostic tools. Then you would of course need a complete code free kit. I haven't heard this before, but Shawn seems very knowledgeable on the 6.7. I wonder if any car shops around have one of those expensive diagnostic tools that we can mess with.
