No, that's it. You are running it.
It's not final, because there is a lot of stuff that needs to be enabled in the windows software, but the general control is there.
Quick tuning guide:
- Setup your MAP sensor type. For now, the TIP sensor must be of the same type
- Set your overboost pressure (max boost allowed)
- Set your gear targets
- Start control (PSI) - The pressure at which the boost control starts. Set this below your spring pressure. 1 psi is probably good for this. Set it higher to try and reduce PTB. Set it lower if you want to build boost faster.
- Spring pressure (PSI) - This is your spring pressure, i.e. the pressure your car makes on spring control alone. If you don't know this for sure, you can take a guess, because it will be learned for you. But, AIM HIGH. Higher spring pressure = lower boost, lower spring pressure = higher boost. If you are way off on the boost, adjust this accordingly until the boost is close.
- Learning range (psi) - When your boost is within this number of psi of the target pressure, the learning is enabled. This will make small adjustments to the boost and spring pressure to learn and stabilize the boost. Increase this range to allow more learning over a wider range, decrease this range to decrease overshoot. 3 psi is probably a good value here. Maybe 5 psi at most.
- Ki - Gain. This controls how fast the boost responds to changes. It doesn't change the spool rate much, but it controls the boost adjustment that prevents the boost from falling off at redline, for example. It also controls how fast the spring pressure is learned. LARGER numbers are LOWER gain. SMALLER numbers are HIGHER gain. Decrease this number if your boost isn't responding fast enough or if it is failing off at redline. Increase this number if the boost starts to oscillate.
