what I was saying is I was not trying to target 20kpa. I was trying to target 20 psi. Or 34.7 psi absolute. But links unit labels suck like I explained below. the confusion is that link doesn’t label their units correctly. “Psi” means relative psi. “Psia” means absolute psi. They need to put “psia”, not “psi” if they want people to know it’s absolute psi. Even in all their instructions, they don’t mention that the table is absolute psi And I totally understand absolute pressure. You don’t have to explain it. Been tuning cars that use absolute pressure for about 20 years now. It’s just that link didn’t have it labeled as absolute pressure. They had it labeled as relative pressure.

I have it targeting 20psi, not 20KPA. Since I have everything scaled in PSI, a boost target of 20psi should be 34.7 PSi absolute. And even the graphing shows this, as my target psi is higher then the actual psi. I don't want anything in KPA. Where I'm from, we use PSI, not KPA. Why is there no ability to change the pressure scaling for the boost table? And are you saying the boost table is absolute psi, and if I want to target 20psi, I should put 34.7 psi in the table?

So I'm tuning an EVO with a Link ECU. Tuned the boost in open loop first, had it holding 20psi just fine. Got a good wastegate duty map from that. Next moved to closed loop boost control and I don't know if my settings are wrong (Set them up according to the instructions) but the P&I is pulling a bunch of wastegate duty, even though I'm below boost target. Any idea why?
