After Tune

If I get tuned, is it better to leave the ECU in OPEN LOOP or CLOSED LOOP during normal driving after the tune when I take it home? Do I want the ECU to manage my setup or do I want the maps that have been tuned to take precedence?

It should be in closed loop when properly tuned.

that is unless your o2 sensor isnt working properly and reading off.

i tuned mine on a dyno and used the dynos wideband, as i trusted that one, and it was 12.5 when my stock one read 14.something in kmanager....

OK... next question. When I road tune do I want to put it in open loop or leave it in closed loop.

I figure I should put it in open loop, road tune/datalog and adjust as needed. After all adjustments put it back in closed loop and go on my merry way.

Does that sound right?
