I've programmed a few handy tools which are practically for remapping, so I wanted to share them with you.
I will expand it regulary.
Let me now if you have wishes!  Smiley

1. KRKTE calculator
= Calculates KRKTE as precise as possible to the given values. No need to use formulas.





2. AFR / Lambda Calculator
= Calculates the Air-Fuel-Ratio (=AFR) and Lambda to the given values.





3. LDRXN Approximation
= Calculates an approximately value for LDRXN with the given boost pressure and vice versa.





4. ME7 Immo Reader
= Reads out the immo key out of an 95040 EEPROM. Handy for learning a new ECU to the immo. A .bin-file of the EEPROM is needed, you can use ArgDub's software for that.

Nice job, and thanks for sharing. Might be nice to have psi in the LDRXN tool, as that's what most aftermarket boost gauges read in, and most beginners can readily relate to.

Thanks for the feedback.

I updated the KRKTE & LDRXN Calculator to support Fahrenheit and PSI.  Smiley

Did you compare the result with the factory settings?

1.8t 180hp stock krkte 0.10306 with 317cc
and yours 0,09425041

This also does not seem correct.  Smiley

Maybe make it default to 10 when psi is selected?

That's because the stock KRKTE is calculated with the following values (it's in the Funktionsrahmen):
> 1790cc engine size and 4 cylinders
> Temperature 0°C
> Atmospheric pressure 1013mbar
> Humidity 0%
> Injector flow rate: 317cc/min
=> 0,10213692 KRKTE

Like said in my first post I try to calculate KRKTE as precise as possible using many chemical and physical formulas. VW used some fixed values in their formulas, I calculate everything, that's why there's still some difference.
The advantage is that you can optimize KRKTE to your climate conditions. Wink



This also does not seem correct.  Smiley
You have to change the atmospheric pressure manually when selecting PSI, that's why I colored it.
I can change it if you want.

EDIT: Just updated the LDRXN Calculator to set the atmospheric pressure to a default value. In addition I optimized every tool to run on every computer, because I saw it looks different on different graphics cards.

Why is the displacement 1790 instead of 1784??Is it just a fixed value that vw/audi used???Also injector flow rate in cc/min I would assume is at 3bar correct???

My fault, you're right, its 1784.
Injector flow rate is dependent of FRLFSDP, by factory at 3bar.

There's much work behind the KRKTE Calculator, that kind of feedback is not very motivating...
=> First you guys wanted PSI, so I added PSI.
=> Then you guys wanted a default value for atmospheric pressure in the LDRXN Calculator, so I added a default value.
=> Now you guys complain about the KRKTE value. What should I do, I can't perform magic?!

My KRKTE Calculator delivers exactly the same value as other KRKTE Calculators (with 1000 atmo, 0% humidity, 0°C temperature), you just have the ability to apply more settings in mine.

I'm not complaining just wondering if it was a typo or a fixed value that vw used that's all.In regards to the injector flow rate I would assume this means whatever the stock fuel pressure is in the car??

Released GagTools V1.2.

Changes:
+ Added an AFR / Lambda Calculator, handy for tuning diesels
+ Renamed "Ldrxn Calculator" to "Ldrxn Approximation"

I would like to thank you for your work on this, the fact that most people dont seem to understand
is that this stuff is just a guide, the calculations from this might not work out perfectly everytime
once one a car, as i like to say there is a whole lotta life to go wrong between the computer and the
wheels.
