I was going to wait for Gav, but im impatient. I plan to weld it into the decat pipe, primarily because its mild steel, and easier for me to weld to. Im assuming, that being furthur back, wont effect my readings, assuming no exhaust leaks. Also, less heat better? AND. Innovate suggesst between 10 and 2 oclock to avoid moisture setting in there. Thats fine, but what above front to back, is it better to have it tilted towards, away or straight down in the exhaust? Thanks!!
Thats too far down the exhaust, need to be on the elbow or just below it.. shouldn't be anywhere near the cat.
when the gases are the hottest and less chance of air coming back up the exhaust and confusing the signal.
Im not trying to be a knob, just worth noting. AEM say this : To ensure long service life, the sensor should be placed at least 36 inches (91 centimeters) away from the turbocharger. The sensor will work if placed closer, but will run hotter, which will decrease the service life of the sensor unit. Im going to get under the car tommorow and see what I can do.
the elbow is too hot for a wideband. they WILL break. narrowband is fine in that location but not the likes of a bosch wideband. put it about 50cm down the down pipe. it will be fine there. if you put them too far away then they run cool and can be inacurate, and can be made worse with any leaks in the exhaust. go much closer and they will run too hot and WILL def break!
I've never had any problems with it being in the beginning of the front pipe, nor have I know them to break any quicker in that location.
if you put them in the elbow, they do. i can assure you of that. they reccomend the bosch sensors temperature not to exceed 500c. most wideband kit use the bosch sensor. i dont know about other brands of sensors however
mappers stick the sensor for wideband at the end of the exhaust system for a reason not just for convenience bosch recomend having the sensor mounted away from the turbo by atleast 20inch or more for the best readings and also to ensure the life of the sensor itself
Funny because the good mappers prefer it going in the front of the exhaust if the port is there...I've been asked to put a sensor upfront for when it can be tuned. strange huh.
some do some dont its just personal preffrence like anything i can assure you that my mapper is top knotch, its also the same guy that has mapped bons liner, and also phills s15 in the past, if he ses in the end of the exhaust then end who am i to dissagree
decat is fine...won't run too cold, they're heated...and have it at 90deg to the flow if you're gonna run it closer to the turbo then get a heatsink boss
