The mounting angle advice is trying to stop the stream of condensation coming out from a freshly started cold engine falling onto a bit of ceramic that is warming up to 600C. (You must have seen the water running out of exhausts on a cold morning.) So providing it is pointing basically down at the angles they suggest, its OK. I would carefully consider what happens when the lambda sensor is in the way and you want to remove the engine or the towbar - if the sensor blocks the towbar bolts you may end up with a partial checkmate, especially after the sensor has been used for a while and it has become almost one with the fixing boss... From experience, stopping an engine moving on a jack, with a lambda sensor bashing against something hard, smashes the sensor. Also the engine does bounce around a bit, so the sensor may end up closer to the towbar bracket than you would like. The sleeving on the sensor should end up somewhere dry as well, as it is feeding clean non-exhaust contaminated air to another piece of red hot ceramic inside the sensor as the oxygen reference. This is why I find it bizarre that the Innovate AFR systems all need a fresh air calibration - originally it was necessary, now its done automatically, but its now a part of the American Way.
I ordered a mounting boss and blanking plug, also i'm borrowing the sensor etc so it wont be a permanent install... check it adjust it and done...
Managed to find a spot to tie-wrap the Bluetooth module and route the connector… Just waiting on a 300mm pigtail connector to join up to the sensor and a 22 mill drill bit!!
You do realise Bluetooth can end up being line of sight.. check it actually has the range to get out of one metal cave underneath where you have it, and into the cab.
did you get it working @Ian Bell ? Just check that it’s not going to get too hot there (or wet if it rains).
A bit of fettling on the boss to get it orientated to the flange ok… Just need to get it welded now sometime next week while I’m in the office
You'd ordered your drill before you posted, but for anyone who might not know about them, big drills are expensive for what's likely to be a single use, I used a step drill, they're handy things for occasional use on thin material.
And bizarrely , the Middle of Lidl step drill I bought has managed a lot of work without getting instantly blunt as I expected. But one second running it too fast into stainless steel, it will be a short farewell..
Sadly mine is 4-22 which entailed poking through the other side of the exhaust… Hole saw did a decent job though tungsten tiped for 7 quid…
pigtail arrived this am, trial route after a morning of checking out Edb festival acts… pigtail will comfortably reach into the engine bay, could have connected at a stretch without it …
Went off to the fab shop at my place… Showed them how the boss finishes parallel to flange… This is what they did…
