Flashing TCU
« on: May 22, 2012, 10:35:50 AM »
Is this possible with this process ??
I do believe that it is connected through the CAN bus and would be worthwhile over GIAC Tip Chip as a DIY Solution

I'm still soldering these, I think it's too rare and old for any tool developers to work on now.

So you have a programming tool, flash a new chip and then solder it in?
IIRC GIAC was actually doing it this way for a while as well

Nefmoto tool connects just fine (address 02) but navigating security was beyond me.

The fact that it connects means absolutely nothing besides the fact that the TCU obviously speaks KWP1281.

As I found out LOL
Which makes perfect sense.
For me the TCU is integrated inside the trans so there is no way that I know of to unsolder/program/resolder
Oh well fun thought LOL
