I am about to start my path on ecu tuning.. and of course first my own cars.
We have some Volvos in family, this topic relates to V70 and S80, my2000, with 2.5TDI (VW) engine.

What tools would I get to access these boxes? According to latest listing, KTag does not have a support.

As I've learned, this ecu Bosch 0281001776 /09496667/ H9.2 has memory chip AM29F200BB and immo-chip M24C04.

I can also buy license to official VIDA and VDash, but I'd like have more independent solution.

One related question.. if I solder these mentioned new chips to PCB, does it look like virgin to systems?
