I would eliminate the Ostrich 2.0, for the time being. I would try a spare factory Original $6D Memcal. I would UV erase the PROM in the spare factory Original $6D Memcal and reprogram the PROM with the "Starter" programming. I would likely UV erase and reprogram the spare factory Original $6D Memcal PROM with same changes that were tried with the Ostrich 2.0.

I don't think there is a problem with the Ostrich 2.0 or ECM, maybe the Memcal is the problem part?
