Silly question perhaps but why don't you fix the eeprom with a hex editor to remove the P0601 code. Bootmode the ecu flash the newly fixed eeprom file the the 95040 and then also flash a new stock file on to the ecu and see if it runs?

I'm guessing something in the LC code is screwing up the checksum process. Many have seen this before; it touches RAM that isn't actually unused.

if i were to delete the po601 dtc will this issue still exist? as in the code will not appear but the symptoms will still appear?

also i thought the dtc was in the ecu main flash file not the immo bin???

It shows the bits that are changed in the eeprom when you have the P0601 error.

Read your eeprom, correct this and then flash it back in bootmode. There will likely be something up with your file due to the LC/NLS.

That's why I said to just flash it back to stock again and get the car working if you need it.

Removing it from the bin is a bit of a hack really. Ideally you just want the file to be right and not cause you a checksum error lol  Tongue

Why are you fixing an issue that your tuner should be fixing?

Yes, it is possible it will eventually return.

Your "tuner" did not write the LC code. He just ran the script, which does random things to the ECU bin.

Okay so if I were to send somebody my bin would they be able to remove the script and code in a good lc/nls?
Or is it not possible cause I like having it


And idk if he's a real tuner or not
Do any of you know where the script installs the coding on the file? Cause I can search for the code

Okay well the problem still exists
Is there anybody that can remove the lc/nls script?
because i really enjoy this tune unless someone has a good like 20psi tune they would like sharing with no checksum errors

guidance: flash to stock. read the stage1 community file thread. Learn ME7. Write your own tune.

Or ask your tuner to remove the LC code.

Use tunerpro then. It's free or make a payment for registration which is 39 US dollars. There's plenty of XDF files floating around on here and I'm sure someone will have an original file for your car. Do what Nyet said and make your own tune.

It does seem a bit weird that your tuner hasn't been able to assist since from what you've said this problem is caused by his file.
