Thanks for that Nyet.
And thanks for even bringing that up Justinw2646

Cool, thank you gremlin. Will try to have a look at this. Awesome

Can you tell in short...
What do you want to do?

All 1.8T have same pinout. General there are 4 of kind 1.8T ecu
1. Some models till 2000 year 512 kb, narowband no ECM relay for powering 121
2. Still 512 kb, narowband but have ECM relay
3. 1kb ECU bootmode version 5.12 till about 2002-2003 year
4. 1 kb ECU bootmode version 6.12 from 2002-2003 till end of production 1.8T

OK, so, just for information purposes, my current ECU is 512kb and it is wideband.

What do I want to do? Well I'd like to setup my ECU properly so it can be finetuned, set up nicely without any current running hickups.
As the current ECU doesn't have a "description" file then the setup/tune has been done blindly. I'd like to properly tune this ECU if possible but for that a fitting "explination" file is required which I nor other have been able to find, even the searches through this forum haven't gotten me anything, till now. Hopefully what gremlin has posted is what I need.
Because I have till now had the impression that this ECU isn't tunable any further. So I started looking into other means of getting what I need and the next idea was to swap out the ECU.

So, in very short, I'd like to setup the car properly, by any reasonable means it takes, anyone willing to do this for me/with me is much appreciated and can contact me  but tilll then, I'll try to find out all I can. As always, my way of thinking might not be the correct way and that's why I am here on the forum to gather more information and maybe even change my way towards my goal.

Pretty sure there are no 512kb wb me7.5's out there. unless you mean standalone wbo2 gauge,which is not the same. And swap ecu if its better for you, you will spend tons of time doing stuff on original , its not worth it specially when me7's are so cheap. ( still quite unsure what it is exactly you are tryna do   )

I just want the car tuned for the hardware I am running and I was lead to believe previously that an APH ECU can't be properly tuned. Hopefully the info gremlin has shared helps out with this and an ECU swap is actually not required.

May you believe it or not, my ECU is 512kb and the stock precat sensor on the car is a wideband. No aftermarket sensor on the car.

Wow my bad that is one unique ecu then, I get why you said it now, first time i've seen that.

And yeah like he said and since he posted the mappack , you can use test version of winols to basically do everything except save the bin, if you want you can make an XDF with the map adresses in TunerPro, then you can use it to save etc.
