I am not good in reading logs,But why do you have several Throttle Closures ?

Default Iso 9 - 01-16-2018, 12:22 PM

Hi Terry

Im new to n54tech. I have a f30 n55 335i, bms intake,******* ** and jb4. Im running pump 95 octane down in South Africa. I did the upgrade to iso 9. There seems to be heavy knocking. I cant even log the car. The car idles at 4-5psi, ecu boost is starting at 22-25 psi when i try and log. When i go back to iso 8. The number look normal again. Idle at 0psi,14 afr. Im using all default settings as on page 1. Has anyone else had this problem. Should i just stick to iso7.12 or 8. Thanks.

Yes. Cut one side. The numbers all just seemed to spike. Even afr was getting over 20. Back to 17/3 now and all seems good again. Logs looking smooth and numbers holding good.

Also having similar issues. Idles at 5.6 psi and after a while, it goes back to normal until I start the car again

Default new FW logs - 01-16-2018, 03:07 PM

Wasq - not sure thanks for pointing that out...it felt fine but I see what you're talking about

New logs attached with slow speed CANbus enabled in new FW map 5. Still seeing throttle dip in middle of pull.....

Waqas....did you keep the slower speed CANbus enabled still? Or did the FW actually make it so that you could disable it and ran fine?

I tried both ways with slow speed and without, and didnt notice any differnce. But i am using the slow speed now since terry told me its better to keep it on in our car's that needed theslow speed befoure the new update.

Terry sent me this: You may still need to keep slow speed on but in the new firmware the slow speed is better than old high speed , Slow speed is 6hz, high speed 10hz, sampling.

And Bit5 also no longer used, its full time all the time now.

okay thank you. I posted new logs, still with partial throttle closure. I'll have to see what Terry says

The throttle behavior is normal. In the midrange you'd only be at 100% if boost is way below target. As boost reaches target it's mapped to around 70% in the midrange.

But what is a problem is the boost dip post spool. I think you'll need a user adjustable for spool mode smooth that out by remaining in spool until boost is closer to target.

Cool, thanks Terry so that I better understand you, remain in the RPM range (by keeping pedal steady) just before it has been dipping before going WOT? and/or do I need to be adjusting other parameters to help me out?

You drive the car how you want to drive it. The throttle isn't much of a barometer for anything, what you want to look for tuning at is boost vs.target. And specifically what WGDC is doing when boost isn't on target.

Okay I just wanted to see if there was anything I could do to fix the dip in boost post spool

cripes, I think I could raise FF in just that area to bring it closer to PWM for starters?

I thought those cylinders were logged by default? and the 6 cyl timing on this ISO is for pedal aggressiveness I thought?

Just to clarify, since we're removing the boost solenoid diode, does that mean the blue wires no longer do anything and can be removed from the harness? I don't like having extra stuff in the engine bay, so if that patch is now useless, I don't want it there.

Opposite, actually. It means boost is entirely dependent on the JB4 driving the solenoid via the blue patch, rather than sharing control with the DME, as was done with integrated control.

Wow. Glad I asked before I removed it. Could have gotten messy. Thanks Terry.

cnm135, I just pulled up some of the logs from my other posts and checked those ignition values for 5 and 6, I am seeing values, so I think it is logging...what exactly did you see when you thought they weren't being logged?

Also, I am trying to figure out why my boost spikes a little at WOT and then dives just slightly under the target (and in some instances goes back over target toward end of the pull). I have raised FF globally (since I don't think map 5 is learning up) to try and match FF and PWM better, my next thought was to look at the specific RPM values and slightly increase the DB by RPM to get the boost back on target....

I notice the PWM going a little higher in each instance when the boost is below target.

Any input is appreciated! Thanks guys.

He's probably looking at your logs from the older firmware where not everything is included by default.

My truck doesn’t seem to like ISO. It gave me a Drivetrain Malfunction after I hit the gas, and is also throwing a low boost code. Any ideas? I set the user adjustments as shown in the first post.

You forgot to attach the data we'd need to help you, the JB4 log.

I lowered PID gain just a tad and raised FF globally and now FF and PWM seem to be a good match right now, however I'm still seeing boost oscillations after "tip in".

I am also in map 5 and feel that it should be learning up way more than it is....it varies between 12.8 psi and 14.5.


Thoughts anyone?

I didn't want to beat on it with the drivetrain light on. I reset it and will get some sort of log tonight. Its not gonna be great since I already have a date with a judge, but it'll be something.
