If anyone would like to test connecting to the TCU, I have a test release of the NefMoto flashing software that allows you to connect to custom addresses. Just let me know if you would like to try it out.

I would definitely like to try out this test version for my bro's possible S4 tcu.  He's lookin at an S4 currently and liked the AWE tune for tcu to lower shift timing from 1 sec to .2 secs.

maybe a few tips on things I should expect, I guess.  Other than that, I'd like to test that out.

You dont need to modify TCU software in first stage tuning (2.5TDi 3.0TDi DSG-DQ200-DQ250 boxes with setup on serial DSG cluthes).

Just need to find map/maps that send to TCU information about calculated "engine Nm" and twaek them.

Regards.

Ps. its my first post - HELLO TO ALL :-)

My car has a sheared exhaust valve and I am trying to find some heads for it right now. But once I get my car back up on the road, I am down to try to read it and or write it.

Doesn't look like this went anywhere ultimately -- I'd love to try to start to figure this out.  Not sure my pea-brain will get very far, but I'm willing to try.

The TCU can be reprogrammed using the pass-through reflashing procudure the dealers use. You would need to get the .bin to flash to the TCU EEPROM. Then using KWP2000 protocol, flash the TCU with the tip chip .bin. over OBDII port.

I would pay for someone to write me a tip chip and somehow be able to flash it too my tcu, but i doubt it possible ...nobody really wants to upgrade a tip

I've found what I take to be maps and am beginning to disassemble, but haven't been able to spend much time on it, unfortunately.  Maybe over the holidays...

I would be more interested in the flashing aspect (as opposed to the tuning). Memory layout, addresses, OBD flashing?, etc.

Any ideas?
