valver ECU would end in 105 on the number on the left, not 107 as the williams does in the pic

I was wondering this myself.
If i do have a valver ECU in my hybrid, and a fit a williams gunner chip to it would that be ok?

Gunner chips do not work correctly when used on a valver ECU.

Will the williams lump run ok on a valver ECU? Mine seems to be running ok.

will run but not as good as with a willy ecu
what if you number ends in 103? mine does and my ecu has a raised limit, willy 2 doesnt run well on it thou how can i get it to run a williams map? do i need another ecu or can i have a williams map put on this ecu?
you can getr that ecu remapped or fit a williams chip.
pm gunner and ask him.

do the rest of the numbers match ?
as in S101262***
never seen that before if it does and ends in 103
Bish is using a gunnerchip on a valver ecu an it runs his williams fine, 170bhp on a recent rr session.
nope, the numbers dont match it looks like this...
this is my ecu.. sorry its not clear couldnt add a more detailed pic as it was too big.
the numbers read
Siemens
s101715103 b
HOM7700851741
7700863568
s101715103 is a valver ECU number, however S101262105 is far more common
you could try a willy chip in it
What would you recommend..a gunner chip?
Using the ECU that i currently have (the valver 1) would that make my williams run very poorly as in not accelerating propperly and top end being only about 110mph?
having never done it mate i couldnt be certain
try and get a willy ecu but they are hard to come by
hill power chips defo work, been done loads of times, ring em up
