Limp home mode causes
What kind of things will put the ECM into limp home mode? I just swapped ECMs and I STILL can't get any datalogs in WinALDL or TunerPro RT. This is bizarre.

There's actually 3 ecm modes, normal, fail soft and limp home. LH meaning that the ecm isn't using the processor, and is using the other analog hardware in the box.
Might try disabling all the malfunction flags and see if you can get it to link.

Got any idea what mode is used when the timing wire is disconnected for setting the base timing?

The processor is still in the loop.

This may very well turn out to be the case. We'll see in a few days. I just got a "new" laptop, though and I find it difficult to believe that TWO PCs could do EXACTLY the same thing. I also just got a new ECM...it's in the ECM clinic for minor outpatient surgery. We'll see how it turns out when the ECM is discharged from the clinic.

Just never say never, or assume anything.

That sucks, Grumpy! It sounds like you luck is running the same course as mine lately.
Once all these little bugs get ironed out, it looks like everything should be great. Spring break is coming up and I'll have about 10 days to goof off and work on the Jeep. ECM tuning....cage welding...maybe an axle swap or two...
