I should have been clearer i changed whatever was at the vats address as used in the stock ddrh bin and the
Car won't start without the key.
But it does start with the key and it has an engine checklight on.
Will try tomorrow and see what i can get working and detail what happens thanks
even if it starts without the key and still has the checklight atleast i have learn't something new lol.

changed the address i suspected as seen in the pic it worked fine with no changes to checksum at all.
I had made a mistake in my earlier post i mixed it up 43 to 4b 4b to 43 lol dislexic
And no engine check light .

Pretty sure Kalmaker would not include the cal segment for the checksum, otherwise it will always be changing while tuning.

I would have thought the same for vats ,if it was not turned off how could one bin suit all bcms, as i thought from vt on the bcm and bin were matched pair

BCM and PCM are matched, the EEPROM inside the CPU stores the key that the BCM requests. This thread has some info ... https://pcmhacking.net/forums/viewtopi ... 02&start=0

The supercharged PCM and BCM are paired in a VT too.

Ah ok so if you change the pcm it won't work in vt on supercharged or not ?
something i have never tried.
I thought it was just the vx on flash pcms did that.
