Cons to tuning out EGT's?

[rotor_powerd]

Any cons to tuning out my EGT sensors, aside from the off chance that things go haywire and I melt a piston? I'm not too overly excited about dropping $400 and filling a Saturday afternoon with frustration for something that is almost guaranteed to fail far sooner than it should. Thanks

Nope. Assuming they are coded out properly, the only con is needing them and not having them.

Its nice to know the EGT of each Cyl when dialing in tune. I have them (of course its a bit more expensive on the 6cyl then 1.8) on all 4. It can give you an idea when you can detect knock. Peak EGT doesn't mean you are running lean so its not a necessity if you are running basic OTS tunes.

Wat?

The EGT sensors don't read below 945* c and are not cylinder specific, the are bank specific.

The only help they provide while tuning is as a safety net.

Are you talking about aftermarket EGT's?

I think he's saying he has standalone EGT monitoring for each of his 4 cylinders.

Sorry, yes I have aftermarket EGT's. Sometimes I get carried away with my posts and don't fully explain what I mean.

OP, if its an OTS tune then I wouldn't worry about canceling the EGT readings.

Highly dependent on what kind of tune/setup you are running, how confident you are with the car's condition, whether you have a wideband, etc.

Ideally, you keep them; they are there as a back up safety measure and when they work they don't cause any negative effects. Of course, they are annoying, expensive, and often fail quickly. I use a Wideband O2 sensor to monitor my AFR's which are correlated with exhaust gas temps, but it is still on me to notice if things are lean. I pay enough attention to everything to feel confident that I would notice if things aren't right.

Is it possible to code the egt sensors out properly so that they don't affect you cars performance and also somehow intercept the signal so that you can monitor the egt's with a gauge for reassurance? Just a thought... obviously it is possible with a standalone egt setup but I am wondering if this can be achieved with the existing hardware and just the addition a dual egt gauge of some sort.

^^^^Yea, that makes sense but doesn't really apply to the OP.

You could monitor EGT@O2.

Possibly, but you'd have to have a gauge calibrated to the OEM sensors. It would be a lot simpler just to go with an aftermarket EGT solution.


Thanks for the answers - that's pretty much what I figured. The car might have a tune, I'm not sure since I haven't had time to look into it, but other than that it is 100% stock so I'm comfortable with knocking the EGT's out and saving some money towards O2's, wheel bearings, and other fun items.

You would need to run an aftermarket EGT controller, the stock EGT cannot be used as a measuring device for anything beyond the Motronic system.

Guess what, our Stage II 034Motorsport Wideband Controller has EGT with full USB capability, etc =)
