Force to open Loop

[Slash200]

Hello,

is there a way to force the ECU to run allways in open loop?
It would be much easier to tune with the translator pro.

I am not sure but I think you can unplug the stock o2 sensor to force to open loop. Hopefully someone will confirm this is the way to do it.

I was thinking about putting a switch inline of the o2 sensor so I could switch it from closed to open when ever I wanted but I just never got around to doing it.

I believe that disconnecting the O2 signal will cause the engine to go to an over-rich mode and store a code,
but I guess that could then allow you to tune it back to a leaner setting...?
