LSU 4.2 slcfree build hex

I have a car with a lsu 4.2 sensor and the clasic slc free could use the 4.2.

Is there a nice way to get a build hex file to use this sensor or do i have to change sensor to use the open source version?

I rather not change sensor due to price and curent sensor is already in the car.

PSOC miniprog is on the table and controler is easy to modify.

Thanks in advance.
