no but mine is where the bracket goes to the gear box just after it. Which is in the centre of the bend as it goes into the tunnel

Bumping an old topic here! I'm now intending to weld in my boss on the downpipe, does anyone have a picture of where theirs went? Don't fancy putting it in the elbow to be honest so going for the downpipe. I haven't got a setup on a car to mock it to so I can't see where is a definite no etc! just read the thread maybe its a little too close to the turbo but i have not yet broke it

The lambda on the van's engine is right on the bend, striaght outof the turbo. It's where they where on the saab the turbo came from. On 11th Feb, 2015 robert said:
i tried putting soap on it , and heating it to brown , then slathered my new lube on it

The Saab one may well be a narrowband which aren't as fussy on temperatures. The Bosch wideband LSUs have two temperature limits, the gas stream and the body temperature. If either limit is exceeded, it shortens the LSU life and also knocks the calibration out. Back to the question, mine (the single one after the turbo) 
It's pointing about 45 degrees upwards and well protected. Schrödinger's cat - so which one am I ??? |

Thanks for all the replies, Rod S, does yours give accurate reasons from that distance? As Pedro said underneath (and I have heard before) that is should be mounted closer to the engine?

Readings are fine and stable. The heater inside the LSU can put the temperature up to what it should be, it can't cool down one that is being overheated, RRs would normally have it in the tailpipe. But it's a difficult question as I'm doing what only a couple of others on here are doing which is also monitoring the AFRs on both the inner and outer cylinders before the turbo (using sample chambers to try to avoid pressure/temperature effects) 
Readings (orange) follow the other two absolutely fine but I have an offset, as yet un-explained - of about 1 AFR. Not sure yet whether it is pressure related or just the difference between TechEdge and Innovative controllers. Schrödinger's cat - so which one am I ??? |

My wideband is in the elbow off the turbo, as long as you control the EGT they work fine. I've had one in the elbow on a Maestro for years. I have also run wide bands in the mini manifold pre turbo, but only for short periods to see how how the inner and outer cylinders were doing, although I'm told those readings were probably wrong due to the pressures in the manifold, so it was probably a pointless exercise.. we'll see when I whack the boost up I suppose! |

Here's the datasheet for a typical LSU (Bosch 4.2)

I tend to believe the bosch motorsport info more than the others. Basically the rule is as I thought. Run it as hot as possible within it's prescribed limits. So dependant on your max EGT, which varies a lot dependant on your engine spec it can be close, or further away from the turbo. No simple answer as usual.
