	VAG 2.5TDI AKE 180HP restriction « on: October 27, 2014, 10:38:22 PM »

I have made two Audi with AKE engine.
Both of them have restriction in injection pump ecu.
One of then over the hole engine speed the other one only until 3000 rpm.

Where can i get a injection pump ecu without restriction
Or is it possible to flash this ecu.

When you order a new injection pump ecu, there are no data on this ecu
People who repair VP44 can flash this ecu. Can they also disable restriction ?

You be right there is a restriction in the pump. You can upgrade the pump.
The max. (if I remember correctly was 52 or 54mg/strk). You can read the pump and flash it... you "just" need to find the voltage map inside and delimit,chks...

No idea which tools flash it or if it's the good old manual method.

But the whole "limit" is because the IQ to voltage conversion is done in the pump.
So if you can not extend that map, there's your limit.
