About this file
What this original file is
This is the factory calibration of the 1991 VW Corrado 1.8 (66.2 kW, 90 hp), for its Bosch ECU with hardware 0261200346, part number 037906022DP and software 356636 (1037356636). Use it to put the car back to standard, to recover the ECU after a failed write, or as the base of a tune of your own.
An original holds every map as the factory wrote them: ignition, fuelling and the torque limits, the speed limiter and the emissions controls. Tuners start a file from it; workshops use it to put a car back to standard.
The file is listed for the 66.2 kW, 90 hp version of the VW Corrado 1.8. Check the power on your car's papers: the same model was sold with several engines, each with its own file.
For software 356636 of the VW Corrado 1.8 we sell the original and Stage 1, each made from the same original read. Every file downloads straight after payment.
Read the Bosch ECU with your usual tool and keep the read: compare its hardware and software numbers with the ones on this page before you write the file.
DTC off and speed limiter (Vmax) off can be built on this file on request, for off-road and competition use: send us your read through our file service and our engineers add them (any file £50, from £30 in packs).
Hardware 0261200346 is the number on the Bosch ECU's label. Software 356636 (1037356636) is the calibration inside it: a read with hardware 0261200346 and another software number needs a different file. Part number 037906022DP is the car maker's number for this ECU.
