Hi  friends! :) :)

Please can you be kind and tell me! ???  Is it not possible  to request  higher than  129.99bar  fuel pressure  on  this ECU?  Its  a  Audi S3 2.0T BHZ engine.   I have tryed to raise  fuel pressure  to  136bar. but can not make ecu to request  higher than  129.99bar   when i am  logging it.   i have uppgraded  Loba  fuel pump and  140bar  fuel regulatlr on rail.  THanks.

Yes you can

Thanks!:) Can it be becouse   the rail limiter   is set  to  low?   hope somone will take their time to answaer  a  neewbi!:)

Tell me the maps you have changed and I will tell you what you missed. :)

Thanks Beaviz! I reallt appreciate that!  i think i found a way to request the pessure  now. 

But i see that  ecu dont request the same high  rail presure  on each full throotle run.  Some times it request  136bar all  the way to  redline. but some times it only request as  low as  90-110bar  only on a fulle throttle run.  it meets  desired  AF  0.81 all the way  but  pulse widt is higher at  8-10ms  when it request lower rail pressure.    what detirmes  requested  rail pressure from ecu?   does  ecu request lower  rail  pressure if desired  af is meet? ???  Thanks   all help is  appreciated!!:)

The requested rail pressure should be consistent if you corrected all the required maps.

It will not drop if the requested AFR is met. The ECU will adapt the injection timing in that case.

Which of the KFPRSOL maps did you correct?
