My WB o2 sensor is quite a long way from the engine. It's situated where the left and right banks comer together at the back of the gearbox. It works well - the heater never comes on after starting.

But being this far down the exhaust means it will react rather later than most and of course you can dial in this delay. But the instructions on how to calculate this are gobbledegook to me. Is there an confused person's guide or tables anywhere?

Using tuner studio I eneabled massive EA and at low/med/high rpm looked at the datalogs to see the AFR go rich and used the time from tps to afr to get an idea of the delay.Remember to reset AE if you do this.Might work could be rubbish but I used it ok.Steve
