Can the adaptive values be reset by draining system power (connecting battery cables). Or, are those values stuck in the ecu or becm? I have a sync mate and it works great. I'm not certain if this is harmful to the BECM though?

The reason I ask is I have a freshly rebuilt bosch 4.6 that is loping when idling down. Runs smooth and strong otherwise.. Fuel economy is good and no obviously fouled plugs..

I have yet to check vacuum, plug wires and or o2 sensors connected properly. No faults have shown up on my generic obd reader?

Re: Can the adaptive values be reset by draining system power

Scotty told you how to reset them already. It's called drive cycles.
The lopey idle is due to the camshaft you used I'd guess. I will guess even more that it smooths out when you raise the idle?
Tried telling you repeatedly to NOT reinvent the wheel with this build, but you wanted to save $10 here and there, and are now the test mule for all those parts. Between the cam and injectors, good luck getting it running smoothly.
There is a reason I put the time and effort into the LSx swap....
