Hey,
Need this Definition für my seat leon 5f my2017 1.4tsi dsg 150hp.
Thank u!

I've tried some bits and i know where is n249 

Byte 6 :   X BKV/N115 LSHHK1 N249

Another update...

I've now got the 5 map TVLDMX switch working from the CC set button and brake pedal.

Would like to give a huge thanks to Basano for his help on reading the ram mirror and other questions i had.

My issue on the last bin was a branch address was wrong so it was branching to the wrong place in the ram and also i had set the counter to only see up to a value of 3 in the byte that stores the value for remembering the map switch so this needed changing to 4 so it could see 0->1->2->3->4

I've also attached my internal and external ram dump for a 115T file as this may help someone in the future.

You need to reprogram in boot mode as flash without daughterboard is not readable by the ECU.

So i desoldered the MTM Board. Old Flash is on. But i cant get in the ECU. I try to get id via MPPS but no answer.
Did i kill the Flash? I see no broken IC`s  or anything.

you wont be reading that ecu with nefmoto or any other software. nefmoto is me7 only and that ecu is m5.9.2. if you really wanted to you could remove the chip and dump it in a chip burner but i wouldnt waste my time. you can write to the ecu using mpps

Thanks. I remember Giac soldering chips on for tuning. Can someone tell if that is a Giac (or other aftermarket) chip?


I have 2 other 557P, those were flashed with MPPS (Daz initially, I think later Mirza), I forgot how they performed. Only wrote down 18 psi, readiness checked and 'tune outs'. So assume stage 2 tune. Don't have a car anymore to test them.

I'm aware of what the 512 hack is and the principle behind it, but as where to start I'm at a bit of a loss.

IE Which maps to change for a ME7.5, double or half them etc

Any pointers\URL's to get me started, an example tune where it's already been applied would be nice

first off its 5120 (meaning 5120millibar) are you writing it wrong because youre lazy or you have no clue? also look on the forum you think someone is going to spoon feed you lol, right.

I have this 557P ECU from by AEB A4. I don't know anymore what tune was on there. IIRC the AEB ECU were literally 'chipped'. Back then I was in contact with Giac, got a decent tune from them (quite aggressive stage 2).
Can someone tell by looking at the photos what 'chip' might be on this one? Or can I read out with Nefmoto and then someone can tell?

immo blink only if write ori file from Alientech
if i write readed file+mod i have only ecu broken dtc
