um, well you hook up the o2 clamp to the pin number 60 in the ecu. so i think that means both, but im not sure.
yea the reason why the emanage is not doing anything while you make changes is because your trying to tune in closed loop and the car will win the fight between the emanage. so what you have to do is force the car into open loop, so the ecu sensors cant do s*** about it, lol.
good thing you have a wideband. you are able able to see the closed loop switcing over to open loop while your drivng. open loop usually kicks in either when starting up the car, and at wot (ideal, but not neccessairly happens right away). and closed loop is when the car is cruising and when warmed up.
closed loop- the stoichometric ratio for cars are 14.7:1. that means there is neither no fuel or air left in the chamber. so therefore, it is ideal for a car to stay around 14.7 when crusing because that is best for the engine. but the car can not stay at 14.7 because the car will overheat, so the wideband should bounce around when your watching it. closed loop is decided by the cars sensors and the sensors tell the ecu what to do. the sensors are too strong and thats why you can not tune the car at closed loop.
open loop- open loop is a preset map that the ecu has, and when the car is at full throttle, the car switches to the preset map and runs off of the map. the ecu stops using sensors, so when you make adjustments with your emanage, it is not fighting with anything anymore so that is why it is ideal to tune at open loop. open loop also kicks on when the car first starts up because the sensors need time for the car to warm up.
this goes into much more depth, but i hope i explained it fairly well. if you have any more questions, post up. good luck with tuning, and have fun!
