You need to change the RPM axis (the bottom row of the boost target table):
Change from:
Code:
200, 400, 600, 800, 1000, 2000, 3000, 4000
To:
Code:
3000, 3500, 4000, 4500, 5000, 5500, 6000, 6500
The new table is shaped like real driving:
Closed throttle (TPS 0%) row: All 100 kPa = no boost at all, ever. The turbo gets a break when you're not asking for power.
Light throttle (TPS 20-40%) rows: Tiny amounts of boost 105 to 130 kPa (0.5 to 4 psi). Cruising on the highway, light passing, normal driving. Smooth and gentle.
Medium throttle (TPS 60-70%) rows: Moderate boost 145 to 158 kPa (6.5 to 8.5 psi). Pulling onto a highway, accelerating up a hill.
Full throttle (TPS 90-100%) rows: Peak boost 162 kPa (9 psi). The most you can safely make on stock injectors.
I did not see this post when writing my last one. That answers one of my questions, thanks! I'll try these out and it definitely makes sense vs. just having a flat boost target.
Stock 265cc purple top injectors =====> Needs settings I suggested ===> Unless you can verify the fuel pressure on your car this is the safest bet for now.
Could you elaborate on the reasoning for this a bit, should I only go to advanced if I can't get good boost control results only using the sensitivity slide? Closed loop boost control in general was a bit confusing for me, does the rest of the cl bc settings look normal?
Source: MSExtra forum thread "what's going on here? MS3-pro PID boost control tuning"
"In basic mode, the code just sets the PID gains to 100-100-100.
Advanced mode allows you to change them."
And also:
"Depending on the version of the firmware, tuning P only will never reach the target.
Your best bet is to go back to basic mode and tune the sensitivity slider to get you
to the target with minimal overshoot and minimal oscillation."
Boost Tolerance is Off. Worth turning on with a value of about 30 kPa once you have basic boost dialed. It tells the ECU to ignore tiny fluctuations within tolerance and only react to meaningful deviations.
The forum messed up the formatting for the Boost Control Pasting into Tuner Studio ; attached for you.
Code:
The rest of your CL boost settings:
Good: Algorithm: Closed-loop correct for a working setup
Good: System type: Single Solenoid Good: matches your EBC
Good: Solenoid frequency: 39Hz Slow — fine for most MAC valves and similar
Good: Min/Max Duty: 0/100 standard
Good: Lower CLT Threshold: 170°F — sane, prevents boost control from running before warmup Good:
Lower Limit Delta: 100 kPa — this is your "open loop until close to target" gate. 100 kPa is wide; you're effectively running open loop with PID kicking in only near target. 40-50 kPa is tighter. Once Basic mode is dialed, you can reduce this for finer control.
Upper Limit Delta: 20 kPa — if MAP exceeds target by >20 kPa, system goes to closed (zero) duty. Reasonable safety net.
Max Rate: 500 kPa/sec — rate limit on duty cycle changes. Standard.
Edit: Just keep in mind that we are changing a lot of settings and this kinda puts you back at base map territory the fueling will for sure be off, but now that we have a solid base the VE changes will start to have a real effect.
I appreciate the sources, I will do some more reading on the topic.
I totally understand we're taking some steps back here. Good news is the fuel map wasn't even close to being dialed to begin with
I'll make these changes and get a good driving session in later today. Thank you.
Good deal and the data logs will tell me where the fixes landed and how to adjust, this helps me develop my software while helping you at the same time.
Edit: If you are using Auto Tune during logging or making adjustments at all then I do not need those logs, I need it with just you driving, the adjustments while driving will obscure data.
Alright the new ae curve worked like a dream, I really should've used trubokittys base map instead of whatever one I did.
Drivability got much smoother, but looks like it's running rich almost all around. I didn't hand tune any part of the fuel table yet, as much as I did want to adjust at least idle, to let your tool do the heavy lifting.
Boost control also needs adjustment as I saw it overshoot target pretty badly before evening out, I'm assuming that's tuned by the slider. Info is attached, looking forward to the next iteration.
I've got some new data for you so far I have only made changes as you mentioned them, no input from my end just fyi
The log got split in two because TS froze in the middle for whatever reason
