well my setup is almost complete and i am going to run uberdata, but i am not going to have a o2 sensor, just my wideband, so i will be running in closed loop mode, my question is, i thought in closed loop mode your ecu ignores the sensors, so wouldn't it ignore the map sensor also? so couldn't i boost s much as i want in closed loop mode?
thanks guys

Closed loop looks at the O2 sensor to make corrections to the amount of fuel injected.

Open loop ignores the O2 sensor for sure, I am sure that it use the TPS, MAP and ECT sensors to determine fuel and timing from a predertmined fuel/timing map. Just out of curiosity, why will you not be using open loop?

I believe that there are wideband O2 sensors that can mimick the signal needed for the ECU.

 

i wont have a o2 sensor, just a wideband

 

it will still look at all other sensors just not the o2
