SlightlyEvil Posted June 2, 2008 Author Share Posted June 2, 2008 Ahh ok so is it safe to say the further you get from stoich the less accurate the stock sensor will be since there's so much going on under those circumstances anyways for the ECU to juggle (loaded engine I mean vs idle or cruising). So it could more accurately measure the difference between 14 and 15 then it could between 11 and 12? This also why it just pegs at 20+ for a instant when lifting?

LittleBlueGT Posted June 2, 2008 Share Posted June 2, 2008 The stock sensor needs to be taken with a jar of salt, not just a grain. You really need a wideband to get an idea of whats going on. Stock sensor is just as good as a WBO2 for accuracy, and it is placed even closer to the engine for better accuracy, especially at lower engine flow levels, like idling, slow speed cruising. It is when pressure comes into the picture (on boost) that its accuracy goes off. You could put a WBO2 into the OEM spot and it would do the same thing.

The ECU is fine juggling different things. Read the above post. It pegs at 20 when you lift because no fuel is injected when the engine is decelerating with no throttle.

SlightlyEvil Posted June 2, 2008 Author Share Posted June 2, 2008 Thx for the answers. Anything like the vaca pics or whitepapers that provides technical data on the stock equipment ranges like O2 sensors etc and what their range, and what the stock levels should be? Looked all through romraider.org and haven't found anything, esp for our cars. Link to comment Share on other sites More sharing options...
