I understand that so my question is, and bare with me as I am oversimplifying, but isn't long coding basically like switching maps? where the maps are already stored in the ECU and only accessed when told which ones to access via long coding?

Also, I'm asking in regard to my V10 swapped B5 S4. But the information would be handy for a C6 S6 I have manual swapped recently as well.

Another question.This is an Excel spreadsheets to calculate afr from 002 block from Ross-Tech site but it doesnt work for agu log.I think must change the constant value.What is for m3.8.3 ecu?

Being that the Arduino is trying to replicate the OE MAF signal, it seems like KFKHFM would apply, though it’s ability to make up for the potential inadequacies/discrepancies of the Arduino remains to be determined.

That being said, agreed the rs6 method is much cleaner, thanks for pointing this out and also agree the barrier to entry with Arduino is much lower (I will go learn how to implement the routine in the ecu). The trivial algorithm that was pointed out is exactly what is bing used (nothing fancy), just outside of the ECU in a separate controller.

As was pointed out, the loop rate of the Arduino vs what the ECU is expecting is a point of risk along with how fast the Arduino can respond to changes in airflow.
You will also have clock synchronization issues because the ECU runs in 1ms raster etc.
My point is just physically wiring the two signals together into one and feeding it into the ECU won't really be any worse than the Arduino for precision and will be much more reliable.
Linearizing them separate in the ECU and then adding them together is the only thing that is better.

KFKHFM criticism does not apply, I forgot that the axis for KFKHFM was rl. So it does not matter if you apply it to each individually or to the whole result. The RS6 applies it to each individually though IIRC.

You ever figure this out?  I am going to be updating mech unit potentially in my mk1 TT as well, probably run into this issue.

Sorry, no (switch mentioned by Leonhard tested on Fxx mechatronics with no luck).

Just use EDC Suite for EDC15
Freeware and has all you need for a simple stage 1

But to answer your question, you might have pressed m, just press w to make it smaller

No, because coding is variant switching, and if the dataset contains only one variant (as in this case) then no matter what you put in the coding it will use only this variant.
Also the moment you disconnect the TCU and set the relevant parts of the dataset, your ABS/ESP will stop working because it too expects an automatic transmission.

Unless it's for an engine swap, in this case you will need to adjust the many functions in the ECU's to get the idle behavior right.

If it's not for an engine swap then forget it. The work to do it properly costs more than the car.

Why not immo off the MAP file easily done with 6 changes
How can I do this mate ?

Hello guys, this is my cold start log.

Note, RPMs and my AFR start fluactuate about 125 sec. Where is my coolant temp about 45.75 C. AFR fluctuate between 0.9 and 1.1 so engine wants to deal with it by rising and decreasing fuel and rpms.

What can I look at?

Thanks for advice.

Post file and ID, it is easier to help that way.
