Is it possible??
Is it possible to drive the oil injector pump on a s5 t2 externally? It it pulse , or just variable voltage depending on rpm? If this is the case, anyone have the voltage range?
Odd ball question, but its a question I couldn't find an answer to. Thanks in advance.

i'm not 100% sure what you are asking, so here goes.
the S5 has basically 3 parts to it. the mechanical part, which is basically the same as all the mechanical pumps.
the electronic part we can divide in two. to physically move the metering pump "rod" position they use a stepper motor.
the second part is a position sensor. so the ecu can give an instruction and via the position sensor it can verify that it is working.
its exactly the same as a drive by wire throttle body.
so any stepper motor controller can run the thing.
if you're asking the other question, the ecu is looking for certain OMP positions at certain points, so you can't really fool it
