OK, so here's my question, and I'm hoping someone will know if this is possible.

I have 2 good ecu's. One is a 06A906032LP with a APR Stage1 Chip (manual ecu) and the other is a 06A906032HF Stock (5 Speed automatic with tiptronic ecu).

Can I de-solder the APR chip and re-solder it into the Automatic ecu? Will it work, or is the APR chip specifically for the manual ecu?

If it is possible, is their anything I would have to change with the checksum's, programming, etc? I believe APR encrypts their chips, but i'm not 100% sure.

Any help would be greatly appreciated!

Note: Both ecu's are for the AWP setup. But I know you can't change the soft-coding from a manual to a automatic.... Freaking 1.8's

AWP tune should be a flash not a chip. So I do not think you have a APR chip.

What the hell is this then that was soldered in place of the factory chip?

Volcano is right... our cars are flash tunes... not a physical chip. No idea what's soldered on your ecu.

Weird... I wish it didn't still have the immo on it so I can test it. The person that was sold it to me did have multiple name brand items of the mkiv gti. And he swore it was a APR Stage 1.

But since I can't get it running on my car, I'll never know.

I do know that I couldn't read the .bin with nefmoto so it's just strange...

I think all AWP tunes where flashed. Only older engine codes where a soldered chip.

But do not hold me to this information since my car is a 03 and by the time I got the car all tunes where being flashed.

That could explain it....but it is from a awp motor, anyways I sent it back after the seller wouldnt respond and tried to delete his account. got my refund, too bad i removed chip from it.... He tried to screw me over, so I pulled the chip off the ecu before sending it back[flame]

Apologies in advance for resurrecting a six year old thread but I must correct both you and Volcano here as you both clearly have a lack of understanding of what is actually going on when an ME7.5 ECM is "tuned." First and foremost, to answer the OP's question - that is a riser chip that has been installed by APR when the ECM was sent in to be "tuned." APR will desolder the original AM29F800BB-XX chip from the PCB, flash the modified file to a flash chip of their own design and then solder the new riser chip in place of the AM29F800BB that was removed. In addition to containing the modified "tune" file APR also attaches an encryption board to prevent people from reading their file, copying it and distributing it as their own. Now back to the topic of what exactly happens during the tuning process. Hambone64 and volcano are correct in saying that, yes, a modified binary file can be either bench or port flashed to an ME7.5 ECU thereby turning the unit into a "tuned" ECU; however, this is only part of the whole picture and you both misunderstand the purpose of the AM29F chips found in ME7.5 ECM. You see, the AM29F chip is what actually stores all of the relevant maps (scalars and tables) that dictate how the vehicle seamlessly operates and behaves under certain conditions. It is these maps that are actually modified when a tune is flashed to the ECU which in turn modify the way that the vehicle performs and adapts to various input variables. In theory, this chip could be removed and replaced by a different AM29F chip by way of desoldering old and soldering new but this would likely result in a seemingly "fried" ECU to those who lack the understanding of the purpose of each IC chip on the ME7.5 PCB. Once again, sorry to resurrect old thread and inb4 "nobody cares dude" but I hate to think that the replies by these two gentleman might misinform anybody who happens across this thread when they are egregiously incorrect.
