Hmmm wrong part of the code then...

Ok then.. try 0x5116 for DSZT, and seems to line up with DKDC (and probably others too). Its set to 0xFF and looks like divide by 40 to get seconds of torque control. So 0x00 would disable it, or you could make it a lower number to retain some torque control.

Thanks Ryan

Is this a X*0.1 for AFR Delta table? If so, I'm not seeing anythign that would give me 17.0:1 Command AFR :S

not sure if it's the same as vs, but vs is an addition to afr.

Correct, its a delta value just like VS. The equation is (1638.4/(111-x))-(1638.4/111)

What's the checksum calculation for the VY?

Would be great to add it to the XDF rather than have to wait for teh flashtool to checksum the pcm on each flash.
I seem to have trouble writing calibrations when Flashtool pops up to correct it, but all smooth if I have it correct to begin with.

Its 2000-1FFFF but need to ommit the bytes at 4000-4007 (which includes the checksum). The Tunerpro checksum plugin feature will solve this issue though.

Yeah the trouble is a timeout I think (another member has similar issues), something on the bus must start talking again so will be changing it to look for heartbeat and disable chatter again. If your really fast at selecting yes to correct it it may not happen. Have not tried that though.
