VT V6 VATS Removal

[vc81]

Hi all,

I'm turning off VATS on a standard VT V6 memcal. This will be the only mod done. When I do a compare, the checksum on the original bin is 0F56 and the checksum on the new bin with VATS off is 0F5E.
I think I read somewhere & I can't find it again now that I need to put AA or $AA in the checksum in the new bin?
Is this correct?

Thanks,
vc81

No only need to change to AA if the checksum calc isn't working!

I'm not sure that calc is right but assuming you used the correct XDF it should be!

So how do I tell if the checksum calc is working correctly?

As it a $A5 revision C bin I used this attached xdf.

The checksum is correct for just a VATS off change. The VATS flag is bit 3 (which is hex 0x08) and your checksum changed by 0x08. Wont need to set the program ID to AA.

Sounds good, thanks vl400.
