I've been doing lots of reading for the past period
Been working in maintenance workshop of a Ferrari, Maserati, Bentley, Ducati, Jaguar dealership
So I have a solid base of knowledge.

I've read and understood the bare minimum about tuning like AFR, Timing, Forced Induction, Fueling, Boost.

I got my copy of VCDS years ago. Started logging and got comfy with the values and their representation and I'm able to diagnose problems and fix them with my car.

Now, where should I go?
I'm trying not to invest in expensive tools as I won't be able to ever breakeven as hobbyist and I'm not willing to leave my job anytime soon.

I wanted to read the EEPROM of the ECU and Cluster and start to understand the MED17.5

Does anyone have any resources?
Where can I read more about it or how it works?
Do I need to understand the architecture behind it? How far?
I know that there's no official documentation so does everyone work by reverse engineering?

PS. I've a Computer Science degree if this will help. If anyone have any resources that would help me, please post it up!

Thank you so much pals. Ciao from Egypt!

Cheapest non-dodgy route is:
1) PCMFlash with the VAG MEDC17 TP20 module for read/write
2) WinOLS Demo (to help define maps) and transferring the maps manually TunerPro

There is sufficient info floating around to get most of the maps needed.

I was able to find damos for the CCZB 211hp Engine however I can't find the damos for the CCZA 200hp MED17.5, will I find it very different?
