Why would applying mark I of the software make the tuner work? Note that in the "it doesn't work with v253" case 253 was applied over 200 without reinstalling the empeg image, so it wasn't "already" wrong, either. Also, I let jEmplode upgrade Hijack, so I can't say authoritatively it did the right thing without looking at the code, but I can't imagine if such a bug existed I'd be the first to see it.

When I went to lunch, I looked, and yup, I got the low battery icon. I left the other (1 disk) unit at home, so I can't see if that's the difference now.

I need to do some recrimping in a bit anyhow (I disconnected some stuff trying to get the dimmer to work, but it appears both the headlight and interior dimmer lines in the Chrysler wiring harness are tied to ground and hence useless, and now I'm going to clean up the mess I left) and I'll experiment after that.
