Hi guys,

Can't seem to figure this out, I am trying to get my throttle to open to 100% but it just does not want to play ball.
It's a 1.8T with a GTX30 so every little help in spooling helps.
I'm running the 5120 hack for a few months and everything else is behaving as it should.
KFWDKSMX is set to 100% across the map, and I have filled in KFVPDKD/E based on a 0%WGDC pull, but in any case anything above PR 1.96 is set to 1 and requested pressure ratio vpssplg_w is always above 2.
The log shows vpssplg_w > 2 for every point but vpsspls_w is 0.95 until 5k RPM.

Any ideas? Anything else I can log to help diagnose?

The map simply tells the ECU for each pressure ratio whether it should control filling through N75 or through throttle.
Filling it is done by doing a 0% DC pull with a hot manifold and logging the highest boost the car is able to attain.
Add 0.1 bar to that for good measure and then fill in the table so that the values are <0.95 for the zones where the axis pressure is below spring boost and >0.95 where the axis pressure is above spring boost.

Of course that requires a correct definition of the map. If your defs are wrong all kind of messed up stuff is going to happen.

In Volvos they’re identical from factory for example.

Did you solve this?
