Hello to all,
Probably I wrote about this before, but I didn't continued the work until now...

I have an Audi TT Quattro, 1.8T APX engine.
The original ECU of my car is a ME7.5 512Kb memory and working with narrowband O2 sensor (8N0906018AE_0261206105_1037350745).
Original ECU file attached.

My objective is to improve the overall engine's performance, including power.
For start, I swap the original ECU to a ME7.5 1024Kb memory to work with a wideband O2 sensor (8N0906018H_0261206795_1037360313).

I swap the ECUs and O2 sensors, I made the necessary wiring and it worked.
At the engine I removed the electrical air pump also.
The electrical components at the engine are from original APX engine.

Accordingly to this I modified the following maps:

CLAATR2 - disabled because I don't have catalytic converter on exhaust;
ESKONF - I disabled rear O2 senso, SAI pump, and VVT because APX engine doesn't have;
KFKHFM (MAF correction table) - I copied the map from original ECU because I'm using APX engine MAF;
MLHFM (Linearization of the MAF voltage) - I also copied this map from original because I'm using APX engine MAF;
TVUB (Injector offset dependent on voltage) - Also here I copied the map from original because I'm using original APX injectors;
KAT/OFF - disabled because I don't have catalytic converter on exhaust;
CATR - again, disabled because I don't have catalytic converter on exhaust;
TABGSS - set to maximum because my engine doesn't have exhaust temperature sensor;


Now, I wonder like to know if I am proceding correctly. Can anyone think with me about this "comissioning" and help me starting with these changes?
I think if I don't have these adjustments done and calibrations ok, I can't tune this engine successfully!

Can I have your help please?

Thanks in advance!
Best regards

In addition to what you listed, I made changes to the following:

Lambda control would turn off after a short drive without a lot of these.. maybe not all required but these have worked well for me.

Injectors for APX and BAM are identical btw

Aardschok thank you very much for sharing!
Did you made a swap also?
I will have a deep look at all these maps you posted, I think that a few I never saw so I will try to find a damos with them identified.

If the APX and BAM engines share the same injectors, the KRKTE map should be the same right?

Thanks for your help and sharing!
Best regards

Thanks for the map pack you attached, now I have the axis correct for the KFZWOP! Great!!!
Now I copied the two maps (KFZWOP and KFZWOP2) from nb ecu to wb ecu and there are huge differences! This car ran the last two years with wrong ignition angles! See attached ps!

What are the timing maps for VVT?

Thanks!!!

On nb ecu the KFZWOP and KFZWOP2 have the same values. I copied the KFZWOP from nb ecu to KFZWOP and KFZWOP2 on wb ecu.

Must I copy the KFZWOP map from nb ecu, also, to KFZW and KFZW2 on wb ecu?

Thanks

Yeah I understood 

On timing maps now I have modified:
KFZWOP
KFZWOP2
KFZWMS
KFZW
KFZW2
KFZWWLNM

These maps I copied from original nb ecu.
Now I will write the file on the car and see how it works!

Once again, thanks for your help!!

Are you sure prj? Almost all hardware is the same between these two 1.8's, both use small port heads and these engine codes share intake manifold part numbers.

Maps are different sizes in my two files 

I didn't mean to offend, just not seen this mentioned before - now that I've looked closer at the maps and read the FR I can see what you mean though..
