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.

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.

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?

try and get a willy ecu but they are hard to come by
