WGDC Correction (direct boost control)
I just realized something about it today and i'm not sure if it has been discussed before..
I was under the impression that WGDC correction only works throughout the pull (while you're in open loop) and then goes back to 0 once you get back into closed loop. So next time you do a pull or go into open loop you start with correction at 0 and WGDC as it is in the tables.
Well today i went out to log a bit, and changed my error correction and WGDC tables to run less boost. I put around 26psi for boost desired and got a spike to 29, so by the end of the pull my correction was like -24. because i have -20 in my error correction table if i overshoot it by 3 psi ( which after today i will definitely reduce by a lot). I put it there for safety after i changed the values without logging..
I'm sure i was the only one unaware of this
Long story short, every time correction is used it compounds, but not only throughout a pull (as i thought it did), but until you restart the car. Which means very conservative values will need to be used in the Boost Error correction table, which is less safe i guess...
