    SD ops back to stock

    I switched my 04 lq4 to 1 bar SD op system, well engine blew up last week so I just installed another one, is there a way to get my OP system back to stock so I'll have closed loop again, running this engine stock so no need in SD

    You should have saved the stock file just before you switched to the custom operating system. However, you can run closed loop in SD also. Turn your fuel trims on if you had them turned off.

    Speed Density is not just another name for open loop.
