Open loop just means the O2 is not compensating the fuel tables so it's the same as having no O2 ... This is done in order to get readings on a wideband directly from the fuel map and not a compensated value based on the O2 corrections

So all I need to do is remove the O2. What about a check engine light.

There is no jumper or hack to force open loop other than using an ECU editor such as those systems. Yes.
