Hi have been wondering about fitting a scanguage or similar to keep an eye on EGT's in the troopy. Can a scanguage get any codes from the exhaust side of the engine that would benefit?
It has a DP Chip and 3" exhaust, and i do a bit of towing also.
Is there a simple plug in solution like the scanguage, or do I need a dedicated sensor. If so, does the
Beaudesert exhaust system have a port where I could put a sensor? I dont want go go drilling, tapping if I dont have to.
Any experience/comments appreciated,
Craig

EGTBeaudesert Exhaust have a built in port just after the turbo where you can put an EGT sensor. This is the one I brought and they are one of the best available.

Thanks Bruce, just found the port on the pipe, beautifully positioned for easy access, and I have a nice spot above the ashtray for the gauge.
Too easy.....now to convince the wife I need a Scangauge as
well.

Just a quickie..did the sensor have the correct thread for the
Beaudesert pipe, or did you need an adaptor?
Thanks

Hi Craig, you need an adaptor mate, ge the old brain having trouble think which one. When I got my exhaust there they gave me the one I needed, the one is pretty common, give them a ring and tell them the size of the sensor and they will sort it for you.

As far as I know the Scangauge cannot read egt as there is no thermocouple connected to the OBD system and the scangauge reads OBD2 info, nuffink from outside.
Yes, you buy an EGT gauge and it reads it's own thermocouple which is fitted in the exhaust as you know.
EGT's vary about 200C difference across the turbo depending on the position of the thermocouple.
Pre turbo around 750C max and post turbo around 550C max.
It seems most people work on 700C pre, or 500C post, to have some insurance factor.
Fitted pre, requires the manifold to be drilled and tapped for the thermo couple fitting.
Both readings have the same relevance to the temp the engine is suffering, it is just the turbo absorbs heat from the hot gas and uses the heat energy to drive the turbo so post is lower temp.
If you can keep it lower then
well and good.
