The gauges with the memory function are nice because they let you see what your highest temperature was. That's helpful because you also need to look at the road.

hooked up correctly
its a pretty straightforward and simple installation. and it has the peak hold and alarm function - on paper it looks good anyway.but the gauge will go straight to 1200f after i run it for a sec( it goes up to 1600f)and back down to 0 after i kill it. the alarm will only go to 1200 too , but the thing is supposed to go to 1600.even then i know it might be too cold for the high temps of a rotary.
is there any way to adjust or calibrate the thing?
also what are your egt readings with the greddy?

Stop it, youre scaring me!
to clarify what i meant - the max the gauge CAN read is 1600F
but when i crank my car up it does nothing for a little while, then
BAMM - it goes staight to 1200F and stops. it doesnt move again untill i kill the engine -back to 0. i think i should see some fluctuation- right? i think ( really hope!) that something is just wrong w/ the gauge ,pyrometer, or sensor. the only mods i have is a dp and k+n drop in , so i shouldn't be that lean.
anyway, thanxs for the responses- now i know about what to expect when i do get some better readings.
does anyone know if something can be adjusted on this thing or should i just get a different one?

its worhtless to compare EGT readings with someone else because it TOTALLY depends on where you put the probe. A few inches difference can mean a LARGE difference in readings.

I think that it is possible to use the EGT to HELP with fuel tuning, but I would NOT trust it alone. My EGTs do not change NEARLY as fast as the AFR. When I had the wideband in my car, or even without the wideband, I'd hit a leanspot in fine tuning and the EGTs have no chance in hell in reacting quick enough (I didn't tune my car, this happened one time when the guy who tuned my car was in the car with me... we were looking for lean spots, found one!)
As far as I'm concerned, and from input from people who have much more experience than I do, a wideband O2 sensor is the ONLY way to tune your car.
Get ready to spend around a thousand bucks though.... blarg. I'm getting mine in 2 weeks

thanxs for that info. that makes sense. mine is at the very top of dp an inch or two from the flange. i sent my gauge + pyrometer back to autometer . i talked to a service tech and he said it sounded like something was wrong with it. i want to get it back in and installed before i get my pfc so i can compare readings before and after ecu install, also what readings i get after more performance mods . how quick do the readings usually change on your egt? Im hoping i can use the egt to help w/ my fuel tuning.

you dont' need to buy a wide band. just find a dnyoshop that has one and use theres. you can't leave it in the car for normal driving anyways cause they only last a few hundred hours before the sensors die. save your money.

hmmmm, save your money? um, whatever...
10 hours of dyno tuning = $1000
600 hours of wideband tuning on your own = $1000
If you EVER might have to tune another engine, or if you plan on doing any more mods to your car, get a wideband for yourself.
