I just bought an ECU for a 01.5 S4 that has an apr soldered-in chip. The car won't start because of APR's anti-theft code implemented, and the person I bought it from does not remember the three digit code to bypass it. I read the 95040, and was wondering if there were any changes I could make to this to delete this feature. Maybe someone will see something that looks out of place? Thanks!

have you tried to flash it with another bin from a different s4 ecu to see if that worked?

i dont have my other bins here at work but can send you one later if you dont have any from a stock box, i do notice that the codes for the immobilizer are set to a 04, i will post you bin up with them corrected to a disabled code, see if that works.

Thanks, Infin...I couldn't flash another bin because there was an encryption board. I'll try this and report back!

sorry got you confused, i meant another 95040 bin, not a 800bb one. 

Get rid of the socket, buy a flash chip off eBay for 15 bucks, remove encryption board, solder in flash chip and flash away!

PS: Is the board EMCS2? Just get rid of it.

It looks different from others I've seen. It's soldered directly to the circuit board without a raised portion like I'm used to seeing with other company's encryption boards..There are two small logic chips on it. I assume one to hold the file, and the other to perform encryption. It looks like a real messy solder job too hehe. It's not for my car, just trying to help a friend of a friend. Where's the best place to get spare 800bb's?

here is a tbox eeprom that i pulled off another ecu i had, might try load it up.

Post a picture for reference?

And eBay! That's where I buy my chips.

I'll take one when and if I see the ecu again...I should have took one when it was here  >:(

I hope APR doesn't mind...
Here is EMCS2 on a 1.8T ECU with GT28RS program:

That's it!  ;D

did you ever get this solved?

This guy is real lazy, and I haven't heard back from him..I think he is trying to find another ecu...Not every one likes to do things the hard (fun) way like the fellas on here.  ;D

Bringing this back from the dead, well sorta. I have an ecu i was about to try and flash the 180hp 1.8t ruff tune gonzo tweaked with some changes. I bought the ecu that supposedly had apr on it, but it never made more power than stock so i assumed it was bs. I opened the ecu up to mod it for boot mode and i found that same chip.

Im assuming it can be read but not written to?

Do you try to activate tuned part of ECMS with CCS-Switch?
If not, than ECU will operate as stock.


You can read only 1Mb stock part of 4Mb-APR flash in standard boot-mode.
You can't write or change something in this dother-board in boot.

I have an old school APR EMCS programmer if you want to send it to me.
