Boost Control.

Stage_59

I'm having issues with boost control. have the 3 port mac valve wired to pwm1. i make changes to the boost base position and targets, but the duty cycle doesnt seem to do anything. it seems to be raising the boost, but im not able to see the duty cycle or boost target in the data log. target goes from 0 to 100, when leaving from a stop, but stays at 100 after 1000rpm. any advice on getting it working properly?

First, check if valve is operational and properly connected. Go to pwm outputs and choose manual mode. Set duty with slider, and verify that boost pressure is changing accordingly.

2nd. Target is set in absolute kPa. 100kpa = 0 bar boost.
