Title: 06A906018FC M3.8.x NA Post by: Tezotto01 on January 19, 2020, 02:38:22 PM 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? Title: Re: 06A906018FC M3.8.x NA Post by: prj on January 20, 2020, 06:22:58 AM Use turbo ECU.
Title: Re: 06A906018FC M3.8.x NA Post by: tezotto on January 20, 2020, 11:28:27 AM 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.
Title: Re: 06A906018FC M3.8.x NA Post by: Blazius on January 20, 2020, 12:18:27 PM 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 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.

Title: Re: 06A906018FC M3.8.x NA Post by: Tezotto01 on January 20, 2020, 04:56:18 PM 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. Title: Re: 06A906018FC M3.8.x NA Post by: prj on January 21, 2020, 08:17:59 AM 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. Title: Re: 06A906018FC M3.8.x NA Post by: tezotto on January 21, 2020, 08:32:18 AM 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.

Thats weird. If you got 1.8NA engines that means you are anywhere but from the US, most likely europe. So that means pretty much any pre ME7( 1999 or so) car will be m3 or m5, I am sure if you hit up a local breaker you could find some pre me7 1.8ts for cheap.

Thank you very much for the guidance, I know your importance to this forum and your words always help a lot, I am honored when you comment on a post of mine, and I am not ashamed to say that I am your fan. My answer was not for you. Ok, you won, I will choose to change the whole system to M3.8.3 or even ME7.5 I'm from Brazil. Title: Re: 06A906018FC M3.8.x NA Post by: _nameless on January 21, 2020, 03:03:08 PM Why not just flash the existing ecu with a turbo file to the na ecu? Ive used a aeb ecu in a aeg car ( m5.92) with the original aeg software version. Whats missing kust boost control?

Ive used a aeb ecu in a aeg car ( m5.92) with the original aeg software version. Whats missing kust boost control? This may work, but I still have to change the wiring (NA uses 2 coils and turbo uses 4 coils) and change the maf sensor or try to map the NA maf in the Turbo file Title: Re: 06A906018FC M3.8.x NA Post by: overspeed on January 22, 2020, 05:00:38 AM This may work, but I still have to change the wiring (NA uses 2 coils and turbo uses 4 coils) and change the maf sensor or try to map the NA maf in the Turbo file Hardware is diferent, will not work with FI files, cut one cilinder or IAT will no work ... better tune with NA file, by the way it is piece of cake... Just lose n75 control Title: Re: 06A906018FC M3.8.x NA Post by: _nameless on January 22, 2020, 07:03:52 AM correct me if im wrong but here in the states m5.92 na uses 2 ignition signals for waste spark on the 2l 8v aeg its a single coil with wires. on the aeb it has 4 coils but only 2 ignition signals ran to a single icm module that fires the 2 coils at a time in waste spark. i tested this before running the aeg 2l on the aeb ecu and it fired on all cylinders.

Yes, but IAT didn´t work with those... even changing wires... will show -48°C |
