Have you changed the map so it keeps the Lambda values above 0,80, so the cars won't run out of fuel at app. 5200rpm even with your own upgraded HPFP and the ECU starts reducing boost until it's within 20% of requested value?
I had that proble and you made me a testfile with that specification :smiley:

Sorta, on the Golf R specifically its different. For older Audi S3's its different again. The results are the same but the way to go about it is a little bit different.
On face value all ko4 cars are the same hardware and ecu's but looking into it deeper we've discovered that the software is not the same at all.

I would like to have your car at our facility for a few days if possible.

So a gti with AXX engine code and K04, S3 injectors and your HPFP will still have trouble above 5200rpm getting enough fuel?
Or do i read this wrong? :drinking:

Its relative to your perspective. More load (power) requires more fuel than is available at a certain injector on time at a certain lambda that we typically like to calibrate to. You can either request less load or a different lambda or tell the ecu to not care about the on time necessary to maintain the lambda we want. Each of those opportunities however has its disadvantages in other areas. In your specific case, you relayed you were cool with a leaner lambda so that's what we did. Regarding the Golf R and Audi S3 there are some other methods that allow us to keep lambda where we like and injector on time within its parameters so they are different from your calibration and those options I first mentioned yet again.
It can be confusing and I know most people like to lump them all together but we've found that spending a lot of extra calibration time in several different markets around the world with each specific ECU and engine reiteration provides more opportunity than previously available.
There's also engineering and then marketing so I would prefer not to get into how "other companies" do it as I feel that is somebody's next question. :wink:
