Those would be the old part that has failed. The new one has "LXH8T245" stamped on it.

Finally got a "day off" to play with the Jeep and UAEFI. I got it running with the LS coil packs. I disabled everything else I previously controlled to focus on the ignition part. The timing table is what I had with the distributor. Earlier today I captured 2 emissions tests with the stock ECU running the show. After the install, I drove it around awhile to make sure it wouldn't die on me like the earlier versions did. I then did another emissions test. I will definitely have to do better tuning, but it seems to be running. Looks like the upgraded U103 is holding up (at least longer than the old one did).

I'm a bit gun shy still, so I left the factory distributor in place in case I need to do an emergency road-side swap-a-roonie. Swap ignition wires, unplug the rusEFI, and plug the stock coil back in -- back on the stock ECU.

Many thanks to AndreB for working with me on this one. He is truly dedicated to making this the absolute best platform of its kind.

With over a month of reliable driving, I am ready to dive deeper. That new TI U103 replacement is doing the trick for me.
