What are you guys getting for EGT temps on your Defi BF gauge? My sensor is mounted where cyclinders 1 and 2 merge.
This is what I get:

Idle: 450 Celcius
Cruise/Freeway: 600-700 Celcius
WOT: 850 Celcius

I noticed that the car runs really lean when cruising or idling. My AEM Wideband shows 14-15 to 1 air/fuel at idle and cruising.

 

temp looks ok, but a/f seems kinda off forsome reason, i doubt our car run that lean while cruising. btw what are your mods?

 

I should be more specific about the wideband reading. I won't have any logs until my Xede is upgraded. Mods are Xede and Turboback exhaust w/ high flow cat.

Idle: 14.5 to 15
Cruising (maintaining speed, light throttle touch): 13-14
WOT: 11.0 to 11.6

 

all the above is normal. for egt's at WOT, keep it < 900 C and you won't be torching the motor, 850s are good.

air fuels are good as well.

 

I see 850 to 900c on a prolonged 4th gear pull on my Defi BF -- mounted 1" off the head in Cyl 2.

You are right where you are supposed to be.

 

AFR on closed loop cruise is 14.5~15. Open loop (WOT) is a different story.

 

agree.your good.same here also

 

Thanks for the input guys.
