	1,8T MAP sensor size and higher pressure « on: June 11, 2020, 10:56:10 AM »

Hi, in my new project(1,8T, ME 7.5, AMK software) i instaled 18mm sensor (2,5bar), 0281002177 oem code (because of hole diameter in intercooler), software in stock car works with 12mm map sensor(2,5bar) 0261230073. Now ecu shows 1,9bar(ant follows ldrxn almost perfect), but real pressure about 1,3-1,5bar(or absolute 2,3-2,5bar), that means about 0,5-0,6bar higher. Tested with 3 mechanical gauges. On idle, shows 1000mbar. Maybe someone know if these sensors are really different or just different in shape?

You will need to find the datasheet for either, or the stock bins that go with each and compare DLSOFS etc.

0281002177 ( 038906051) and 0261230073 (038906051D) sensors are identical in electrical characteristics.
