So after i do some tuning do i have to put the car in open loop or can i just leave it in closed loop and i dont have a stock o2 sensor

If u have no O2 sensor of any form(narrowband or wideband) inserted in your exhaust pipe,then u have no choice but to run in open loop,closed loop will not work without an O2 sensor.

If u have no stock O2 sensor like u say,then your only choice if u want to run closed loop,is to get a stock or narrowband sensor of some sort or use hondatas fancy new wideband signal for closed loop operation.

So u will have to leave your wideband installed permanently & configure the closed loop options in sManager to run closed loop operation with your wideband signal.

So no O2 sensor,no closed loop for u....

Theres no rules on whether u have to run open or closed loop,its your choice,closed loop would be more ideal if its a daily driver u got there,but if its a track whore,then take all that O2 shit off your car its just slowing u down....

ok thanks. I do have the wideband hooked up to the s300 so ill just leave it closed loop
