I'm running the map ecu w/ a small single and a member stated that by elminating the stock o2 sensors, his car is running in open loop at all times:

I've searched and didn't come up with anything and its the first time I've heard of this. Will this have any adverse affects on the performance of my car or will it even work? Wouldn't it also solve the lean tip in issue with the map ecu since there is no transition from closed to open?
