Hello, just picked up an Audi S4 with the 2.7T engine, car is stuck on ALS 4k RPM matter what gear or speed. Did all the basic electrical diagnostics and VCDS work to verify all my inputs are good. At this point, I believe that I need to read my bin file. After all my research, I'm hoping that the idiots who had it before me put the VNMX at 125 km/h instead of 1.25 but who knows. I've been doing hours of reading the S4 wiki and I still haven't connected to the ECU through Nefmoto yet. Not because I can't, just making sure that I have everything correct before I even try to copy my bin file. Don't want to brick my ECU. Appreciate all the information on here and I look forward to learning more.

But I potentially can brick it by altering the file is what I learned. Better safe than sorry, right? I will take my time, continue with research instead of rushing into anything. Thank you for your reply. I will make a new thread in the proper place when I get the files read and uploaded.

That's where my problem lies. I bought the car as a project, had a hurt engine and blown clutch hydraulics. Has K04/K24 hybrids, injectors (unsure of size), larger SMIC's and MAF housing, full exhaust, etc. Car made 480 whp in current setup with a healthy engine. So I believe that I need to go in and edit out the AL/NLS and leave everything else alone. And from reading S4 wiki, I'm hoping I can alter the VNMX to nothing and leave everything else alone. I did make one mistake, thought I could use the Ross tech cable but it doesn't work for dumb boot anymore, at least the nee cables they sell. So the blue cable should be here in the next day or two so I can read my files, which I will be asking for advice on if I cannot find the problem myself. Thank you for your input, I really appreciate more knowledgeable people chiming in.

Now if the tune was from someone who does remote tuning, would that still be the case? Sorry if that's a stupid question.

Nefmoto shows the option for boot mode however, it does not do anything as the program was never finished. You need to use some other tool like the arcarric Galletto 1260 that's floating around. You will need to modify the serial number in the ft232rl cable using something like mprog to match the serial number galletto software looks for otherwise the program wont work. Other option is to spend a little bit of money and buy something, even the cheap mpps clones work fine and have boot mode baked in. Do not buy MPPS v18 clone, you will only have a handful of uses before the cable kills itself, they are a bad clone and after a few uses the software will not see the cable, known bug that exists in the software. Its the same cable that is used on version 16 but if its used once on v18 it will brick the cable after regardless if only used on v16 after. Clone kess and ktag work fine on this ecu too, kess even has a bootmode option for this ecu too. My advice would be to buy a clone kess as that will flash your ecu, do the checksums, and generally work fine for the low price of like $35-$60 bucks depending on where you get it from. Also in order to read something out in bootmode the ecu needs to be open and the boot pin needs to be shorted to have the ecu power up in bootmode.
