Fuel Pump Voltage Fix without ProTool possible?

[Benjiman]

Hey guys, installed a Walbro 535 and sometimes getting a fuel pump fault.

I'm hoping to try the voltage fix before spending money on a Speedsty upgrade, however I do not have ProTool and not sure I want to buy it just to try the voltage fix.

I have INPA, ISTA and WinKFP, does anyone know if it is possible to use one of these apps to do the voltage fix? Surely it can be done without ProTool?

Thanks for any advice
