My name is Mihai and i`am engineer electronist.I want to convert my audi TT 1.8t 224HP engine code AMU (car from unitedstates) from Narrowband to Wideband
car have quattro esp and cruise control (if is inportant)

I read si many things on forums but to start that conversion i need some shure tested ecu numbers that will fit to my car and after conversion the quattro / cruise control / ESP / electric ventlators will work normally

now the original ecu is 8N0906018K  bosch hw number 0261206894

if someone can helpme with some codes for ecu / lambda etc
and i also ask if a must chance the MAF

Many Thnaks

This is probably going to get send to noob questions but basically what you need is:
1. A Wideband ECU BEA Engine code should be a drop in (you can use some of the golf ECUs but you will need to reprogram them)
2. A wideband harness
3. A wideband O2 sensor

You don't need to change the MAF. Also, google is your friend.
