NefMoto

2001 amu audi tt
Nefmoto does nothing beyond connecting.
I can connect just fine.  38xxxx baud and slow connect
But when I try anything it just fails.
Can't even read ECU data.

I've tried with four different cables. Nothing.

Car and setup used to flash just fine. I out a few different files on here.  But now I'm locked out

Vcds works fine.

I tried pulling cluster fuse.   Pulling cluster entirely. Putting in different cluster. Tried reinstalling drivers. No luck. The only notable thing that happened was that the cable I was using broke. 
Blue cheapo ftdi cable.  Flashed great. Then just started giving a million errors in vcds and no more flash.
I bought numerous good replacement that work in vcds.
But nothing works in nefmoto now.

I attached the output from nefmoto when I try to flash.

Please don't post photos of your screen. rotated even? with this lack of attention to detail it is unlikely you'll have any success in anything technical.

use copy/paste *on the text of the error* or at least have the decency to use the built in windows screen shot hotkey

mybad. I didn't have any wifi on the laptop in my car, and my phone showed that image as being rotated properly.

Here's the copied text.
i just made a fresh attempt to flash with no luck.
I've tried multiple new cables with no luck.
it connects. but can't do anything. can't even read ecu info.

Can you talk to it on the bench?

Also, try a dedicated kline.

ok. I rerouted the kline to skip everything and go directly from the ecu to the obd plug.
it still didn't work.
still connects.
but if I try anything it just fails.

here is the readout from connecting, then trying to read ecu data.

try bootmode (you'll need galetto and a bench flasher, unfortunately).

Or get a spare ecu

Ah fuck.  Ok. I have a bench now, but couldn't figure out hooking it up in the car.
I'll try pulling the ECU.

any input into what might have caused this. or what kind of things cause connection errors like this?
it flashed fine a few weeks ago. Although there was a small memory error before flashing. though the flash went through ok.

bad flash, probably. as in, you screwed something up in your bin.

i'd bootmode flash stock and see if nef can flash.

if not, the ecu is dead.

Well not dead of course because the car runs in its current state.   But yeah I definitely need to flash.

So I got a bench harness going. 
So far no luck.
With galletto. It recognizes the cable and will "try". To read the ECU.
But then it says that it's not in boot mode.

One odd thing. If I try galletto in normal mode. Then it just freezes and I have to close the program.

I've got all pins powered.  3 62 21 121
Also tried not powering 121.

Galletto mentions cycling ignition for 10sec.  Is that pin 62?
This is an me7.5

What are you doing to get it into boot mode?

Just ground pin 24 then add power and remove pin 24 after 10secs then run galletto. 

I also tried doing that after galletto started.

Also tried nefmoto and geletto without grounding pin24.  Nef just says cannot connect at all. 
Galletto freezes up forever when I hit read ecu

I'm thinking maybe I should leave it powered and then cycle it on/off with pin62.  That's ignition right?

At this point I think you need a separate known good ecu to verify your bench cable and bootmode technique are correct.

Ok i got it to connect finally.
Had to swap out my psu.

So my bench harness works properly.
And i am able to access the spare ecu.

However the spare is from a fwd tt and my car is a quattro 225 tt.

Can i flash the spare with my quattro map and have it work? Both 2001 ecus

The quattro ecu is still messed up.
Cannot get it into boot mode no matter what.
And nef wont connect to it.  Nef can connect to it on the car oddly.
But it cant do anything. Not even ecu info.
The ecu runs the car.  But i need an ecu that i can reflash.

What is your pinout for boot mode?
Yes you can crosflash all TT ecus after 2001 year

Mines a 2001 narrowband. And the ecu is a 2001 wodeband. 
Im wondering if the flash nef flashes has the dats that changes the wb nb info around?

For boot mode i ground pin 24
It works with the spare ecu.
This one is just so screwy it doesnt want to do it

No you can't flash NB to WB.
You must find NB ecu or make a little change in harness to put WB ECU

Maybe I should just convert to wideband and use the working ECU.  Ill need it in the future anyways.  And it's safer for a noob like me to tune

theres a 50% off sale at the local parts yard.
can anyone recommend which cars have an ecu that I can cross flash with my car?

my car.  2001 amu narrowband 225 1.8t. k04 6spd manual.
i know it has to be narrowband, and me7.5.  but how about auto/manual, or vvt, or egt stuff?
I wonder what stuff will be converted to work properly when I just put my bin on it.

At the very least you need a wideband ECU, lambda and wiring loom.

On these cars you can pretty much crossflash anything, code in or out the bits you do or don't need. (ESKONF)

You can softcode auto/manual using vcds, but i believe every 1.8T TT came with a manual box.

Well the tt came with auto, 5spd man, 6sod man, and even dsg paddle shift.
Obviously you can't crossflash everything or I wouldn't need a narrowband ECU to match my car.
I'm looking for a replacement ECU now, but I need something that I can flash and it'll work.  Marching tt ECU are too expensive
I'm looking at Mk4 vw ECU narrowband .
But which engine code or car/year?
I guess I need a new post for that

Update:. Just to close out this thread and let anyone who cares know.
The ECU was never salvagable.
It can't boot mode no matter what method.

I got a cheap replacement and called it a day
