Map scheme 3b

[wastegates]

Hello friends.
I need the electric scheme the MAP of ECU of a Audi S2-3b.
Is for a friend whom to change by the 300 kpa and needs the electric scheme.
Thanks

Its pretty straightforward... max output from MAP sensor is 4.8V - divide that by the dynamic range (200, 250 or 300 kPA) to get the absolute pressure per volt.

In short its -
2.40V per bar on the 200kPa
1.92V per bar on the 250kPa
1.60V per bar on the 300kPa
Those are ABSOLUTE pressure values i.e Ambient plus Boost pressure

hello Paul.
Is necessary to replace a Map of 200 kpa by another one of 300 kpa, I then need electric scheme are not equal

Pin out is the same on all Bosch MAP sensors of that type - they are pin compatible.

ECU reprogramming is necessary after a MAP upgrade of course...
