Dont know anything about that ecu or the car, you didnt told, but more than 1000°C on E85 is absolutely not normal.
Are you sure, that it isnt °F?

You should not see more than 700C, it is the all point of e85. Keeping temperatures down. |

You cannot use the EGT model on the 1.8t's. It's horribly inaccurate if you've done any sort of modifications to the stock hardware. Best bet, get a thermocouple and confirm your actual EGT's/

Its a model?
What kind of aftermarket ecu is that?
Or such a "i do my own flashloader and map editing gui and sell the standard ecu as new tuning solution for stupid people?"

No, it's a "I took the time to read the documentation on our ecu's instead of acting entitled and making accusations". Most ME7 vehicles don't use EGT sensors, and of the few that do, many of those are narrowband. When people refer to EGT's they're usually referring to the calculated model the ecu uses. That model is fairly accurate when dealing with a stock configuration. When you change ANYTHING, those calculations are no longer accurate and need to be checked. His 2005 GTI does not have a physical EGT sensor, so the temperature he's referring to is calculated, therefore not necessarily accurate. |

Fix ATM or do something more interesting and get RS6 egt sensors, enable ATR, full range control and be amazed  |

Masterj, that could be a really good mod. Is it doable? Has anybody done it or tried to do it on 1.8t?

Sure. If you're skilled with IDA and hang around for a couple years, it's definitely doable. |

Ok, such kind of ecu. Clear.  I've done this EGT input with Volvo ME7, but with an 0-5V input from external egt Controller. Was very complicated. In winter i'll try to do it via can, should be more easy. |

If you just want to log the value via the ecu that won't be hard. If you want to incorporate that into the egt model, that's another story.

Sorry, but to which hardware are you referring these 700°C? I have done a few e85 cars with Big Turbos and they all hit the range ~850°, which is still fancy low! Lambda round about 0,85. Ddilenger: I don't know which variants you had in the US, but here in europe in fact the most are 1024kb + wideband, but only a few (225hp models) had the sensor, rest is using ATM (150-210hp) from factory. But on these its kind of walk in the park to activate the ATR instead of ATM. |

Think about the laminar and turbolent flame velocity for E85 at lambda 0.85.
Then you know why people calibrate E85 richer and why the EGTs are cooler.
