I was once interested in knowing how the throttle-less valve based multi-air technology engines from Fiat are controlled, but could not find much and later lost interest. But do a search, in some cases it does not take 1 minute and you have to try a couple of queries before google decides to give you what you want

You must be very young to be surprised at the age of these things. They take time to develop before they hit the market, and ME7-s in mass go at least back to 2000. You would be even more surprised if you knew how far back are the roots of the OS of your Android phone (if you have one)

ME7 is the first modern ECU. Everything else, even in this day and age from Bosch in gasoline control is very similar.
1998 were already cars on the market and for sale with ME7 (Audi S4 2.7TT).

Most of your questions are all relevant for ME7. You don't know the basics of how it works and it has been more than 20 years.
So that is why I told you to forget what you're doing now and start somewhere a *little* bit simpler.

Really shit idea to play tricks without knowledge on a possibly leased car where you can't afford to buy a new engine or gearbox.

Ниче, в рашке тоже кредиты берут, правда на тачки поновее.

Anyway, good luck.
