I assure everyone that there is a hardware difference between adaptive and non-adaptive FRMs (at least some versions of the FRM2).

There were two different part numbers, at least for a short period of time:

Before you question my credentials, I've been coding for 3 years. I have done numerous FRM upgrades. In Gideon's case, I tried everything possible, including flashing the firmware on the FRM2. Could it be a defective unit? Possibly... but all signs point to a hardware limitation as everything works except the adaptive feature.

Let me know if I'm mistaken and if you think I haven't tried something, I am all ears.

Another thing, slightly unrelated but worth thinking about in this context... have any of you ever been able to retrofit AHL xenons (with working AHL) on a halogen car (with a halogen AKA non-AHL FRM)?
