Looks good! No other changes needed for Map 2.
Looks super clean. Still want to see if boost can get closer to target:
| duty_15 | duty_20 | duty_25 | duty_30 | duty_35 | duty_40 | duty_45 | duty_50 | duty_55 | duty_60 | duty_65 | duty_70 |
50 | 50 | 50 | 50 | 50 | 50 | 60 | 65 | 65 | 65 | 60 | 60 |
You're banging the limiter on both logs there. Just FYI, the throttle starts to close in anticipation of the limiter at ~6800 rpm or so.
OK, so as soon as it hits redline I should be shifting, not just letting it drag. Makes sense lol.You're banging the limiter on both logs there. Just FYI, the throttle starts to close in anticipation of the limiter at ~6800 rpm or so.
The second log has a clean pull on there. But again, your foot doesn't go all the way down until you're over 4000 and 3rd. Throttle stays above 80% after your foot is all the way down and before you hit the limiter, and boost is within 1psi of dme_bt+target, so this tells me boost control is decent, you're just not requesting very much (map 1 adds +2psi above 6000).
Ignition timing is "okay". Its detecting knock and pulling timing in some cylinders, but not enough to drop all of them like a rock. When your timing starts to diverge from each other, but are still able to (jaggedly) climbing to redline, that's about the limit of the boost you can run with this fuel. Don't need to turn it down, but can't add more.
You'll also notice that in all of your logs, boost drops after the shift and takes 5-7 timesteps to recover. This is because when you hit the limiter or traction control kicks in, you get a "lazy" shift without the fart/brap. Yet another reason to shift a little earlier.
The general consensus is that power/boost peaks way before 6500 and that's when it really takes a nosedive, so there's no point in going all the way. the gears are so short and you only drop 1300-ish rpm between shorts, so even if you shift super early, you'll still be in boost.
When you do a pull, leave it in drive but use the paddles to shift down to 3rd manually. That way it will hold 3rd long enough for you to start the pull and shift automatically when it needs to.
DYNO IT! LETS GO!https://datazap.me/u/coloneladama/log-1713878042?log=0&data=1-2-3-4-11-15-25-26-27-28-29
Been a while now without having to make any revisions on my catless MT. Running like a champ!
- Ideal timing (all ign converged climbing to redline)
- Trims under 40 (2 gal ethanol into 93)
- AFR rock steady
- Boost consistently ~4 psi+ over stock request
- MT technique (LOW WGDC: FF=14, PID 15) (MT firmware needed)
Think its ready for some dyno time?
Looks great! Keep an eye on trims.
No, keep as is. Will go lean if you add any more ethanol. No recommendations, Map is perfect for your fuel and car. Some throttle activity, but looking at the boost2 curve - it fits target nicely and is smooth.
