What could lead to high exhaust temperature?
It’s between 770C to 999C when driving or pushing the acceleration paddle hard!
Then it went down to 600+C if the car stopped due to the traffic.
It’s still the base tuning file and the car is running slightly Rich.
Those numbers (999c) seems dangerously high to me i would worry about major engine failure. You could be running way too rich burning fuel in the exhaust raising temps, could be too much boost causing heat, could be restriction intake/boost piping. Kind of need more info...
The 999C comes with redline!
I think I don’t have a piping restriction, apart from the OEM discharge pipe but it won’t lead to this numbers.
I am going to recheck the mechanical parts AGAIN while I am sure it’s not related to it.
I think it’s due to the rich fueling settings.
I will do the data logging ASAP in order to see what’s going on.
Don't forget Turbozentrum warning.... yikes. Do you have the Aquamist deployed?
Important note about exhaust temperatur
In the past some customers didnt taked care about the exhaust temperatur. Even though the stock turbo is going with up to 1050°C in some cases, this is a) not necessary and b) the death for an EFR turbocharger. Please take care at your programming that the exhaust temperatur never exeed 950°C in any case!
The Aquamist isn’t deployed yet, I want to make sure that the setup will run perfectly with pump fuel only then I will install the Aquamist.
I remember the TurboZentrum warning and I sent to Bronson before, that’s why I have the feeling it’s from the ECU file but I want to know if something else could lead to the high exhaust temperature
Bronson should be able to dial out the high EGT and at the same time give you more power with more aggressive timing and fueling adjustments. Plus you will be cooling the charge significantly with the Aquamist system.
What are you running to get your EGT temps, what to make sure I do the same.
I use the PolarFIS device, I am using it since 2014 [emoji4] it’s very nice device,
I didn’t do the required data logging and send it to Bronson, I am moving to new house so I guess I will do it next week.
