I am working on a naturally aspirated Audi A3 and we are going to mount turbo and big nozzles, I need to find the FGAT0, TLST and KHFM maps.

Can anyone help me with this?

Use turbo ECU.

As this ECU uses a MAF sensor, I believe it is possible to scale the tables to work with turbo, I had the option of using the turbo engine ECU as a B plan.

Trust me, Ive done turbo conversion on NA ecu. In the end its better to use turbo ecu because the manufacturer has already done the things for you instead of you, and most likely they done it better than you can.

You need to spend loads of time searching for maps and etc, instead you could spend that time on actually tuning the car. The ECU's are very cheap either, get yourself a wiring diagram , add/move/remove the required wiring to match factory setup and you done. Its not just about underscaling the MAF.

I still don't understand why this bizarre notion that modifying an N/A ECU to be FI is easier than converting to another ECU persists.

I understand it when there is no turbo ecu available for the engine/ platform but when there is one  then yea. The main thing I would guess based on my own experience is budget builds and lack of experience with parts compatibility/wiring.

For my research KHFM = 0x67B8; TLST = 0x6752; FGAT0 = 0x67B9
You mentioned the same address for KHFM and TLST, which one is correct?

I have not ruled out the possibility of using a turbo ECU, but if I find these maps I will try to play with that ECU a little.

For the final time, just use a turbo ECU...
You will have a full damos for that as well, and won't need to guess.

Yes, I have the DAMOS complete for the turbo ECU and several cars tuned with this ECU, I would like to offer a cheaper solution for those who install the 1.8T kit in 1.8 NA cars, in addition to the ECU you need to change the wiring and replace the MAF sensor, the MAF sensor ECU M3.8.3 (1.8T) is a rare piece in my country.

Cheaper solution? 1.8T KIT for car that is 25 years old?
Sorry, but my bullshit meter just went to maximum.

What is this fine country where there is a massive amount of 25 year old 1.8 NA cars, that people are driving and who for some reason have a ton of money to start tuning it?
Like, these things are worth 1-2k. You can probably sell it and buy for 1.5k-2.5k similar condition factory turbo car.

Person who is driving this old car does not have money to tune it for 2-3x the car value OR they are never going to be interested in tuning it, because car is only instrument to go from A to B.

WTF are you on about?

I just did a search on eBay, there's a ton of ECU's for 50$. M3.8.3 and M5.9.2.
