Vadim,
Thanks for the reply. I got ahold of Dave after posting my message here and he doesn't even have a xdf for an OBDII RTV2. Nor does he know the memory addresses that are used to trigger the registers. He let me know that code would need to be placed in the ECU so it would know to trigger them.
From some of the older posts I read of Calum's, and some of the comments he made to me personally, the RTV2 was intended to be a development platform. So that if someone was interested in developing code to do all kinds of things in the ECU, it was possible. But he did not do much of the coding, he just provided the platform (which was really his mission from early on.. to provide the ECU's for us to tune, etc..not him).
I don't post on here much, or on G20.net (were I'm an admin), but I have copies of some apps (NDS, Tunerpro RT, Logworks, Calumsult (the Logworks version), drivers, and the non ODBII RTV2 xdf.
If I had saw his thread back when it was started, maybe I could have helped out.
Let me know if I can be of assistance in the future.
Regards,
