I need someone who made before or is able to do:

VOLVO Bifuel (Petrol/CNG) 2.0T 157kW 213PS 300Nm
Engine code: B5204t9

VIN: YV1BW63J0E1299973

I had this car today and tried to find the ECU from petrol but have found only two BRC and PRINS ECUs (LPG and CNG) under the windowshield.

Can someone give me exactly the location of petrol ECU for this car?
What tool will read it?
Will someone edit this Ecu? (Will Pay)
