2010 X5M S63 Logging
 
1 Attachment(s)
Finally managed to get around to doing a third gear log on MAP1.
Had been running MAP3 previously on a ~E30 mix (107+98 RON).
Stock apart from JB4+BCM and drop-in K&N filters.

Are the HPFP and LPFP readings supposed to be the other way around?
Was expecting boost to be a little higher with 4psi over stock, or is this not really representative of actual?

Cheers

FP_L is not a real value.

You'll need to set your user adjustments back to the default settings.

Hi Steve - not sure I understand

I haven't adjusted any user values in the interface - only changed between MAP3 and MAP1 on steering wheel.

This is the current settings when connected to the JB4.

Should they be what's used in the screenshot in the above post?

MAP1 is the same with the exception of FF/Wastegate Adaption changes to 100.

I'd like to up the boost (especially in lower RPM) and run more E85 if possible.

Steve @ BMS/Fuel-It! 02-19-2017 03:12 PM

Yes, that is the example you'll need to set your user adjustment values to. Those settings affect all maps...not just map 6.

I've changed User Adjustable Settings to reflect those above but Boost Safety comes back with an error saying value can only be 1-25, so I left it at 25.

Ran another third gear WOT log but ran out of road at 6000rpm.
TRIMS are up slightly but doesn't seem to be increasing boost anywhere across the RPM range, and AFR is relatively unchanged.

Would you suggest trying a custom MAP6, or is there something else preventing higher boost?

Steve @ BMS/Fuel-It! 02-20-2017 09:58 PM

N20 TMAP needs to be set to 1, it's currently set to 0.

Competed in our local annual "airstrip" attack event over the weekend.

Managed 230.14km/h 22.619s for standing start 1000m run.

Logs attached.

Would love to run more fuel (higher ethanol mix) and timing.

Steve @ BMS/Fuel-It! 03-07-2017 07:19 PM

I wouldn't recommend any additional ethanol. Your trims are already maxed out but not ba enough to force you lean...yet. ;)

Thanks Steve - would it be worth looking at upgrading/additional pumps to increase flow?
AFR doesn't seem to be affected?

Logs look good. I think boost is reflecting false high in logs as you checked off 3.5bar TMAP sensor. But on this specific firmware that should be set to 0 since we're not scaling the output to the JB4 interface beyond 25psi the standard setting.

Also note open loop is set to 0... Raise that to 60 to dramatically lower fuel trims!

Thanks Terry - will change those back.

Any other adjustment needed?

Is there a way to reduce the "aggressiveness" of the boost control to smooth it out? Seems to be hunting for boost levels and looks pretty lumpy.

Bump to see how this is going?

m5james 10-05-2017 11:20 PM

Second bump...I see a PID of 8 on one screenshot, 20 on another and different duty bias' on each screen as well Mines been set to 0 this whole time. What happens if I change these and/or what is recommended?

Truck feels like a beast for being...a truck...but I'm always game for faster. So far my best kills are a heavily tuned MazdaSpeed 3, FBO 335's, newest Mustang GT, buddies E60 M5 and another buddies E55 supercharged, then today a Shelby who failed to pull away from me in the fast lane until he gave up around 130 and finally pulled to the right :-) I'm sure there's others but you get the point.

protecon 10-06-2017 12:59 AM

PID was set to 8 when shipped, and as per comment above, Steve recommended setting to 20, in line with N54 default settings.

Haven't really played with settings lately, as waiting to get the WMI in and sorted before fine tuning.

Cool, it'll be good to see the final results.

I'll copy your settings and see how it feels.

Let me know how you go - mines running flawlessly at the moment, which is one of the reasons I haven't played with it lately. Still mixing a tank of E30 in every third or fourth tank, just to keep the DME on it's toes. I see a bunch of people are switching from JB4 to flash-only setups, but I'll be sticking with mine, not only for WMI control, but the ability to customise settings on the fly during events, and not having to rely on a remote "tuner".

WMI install is taking a little bit longer to pull together, as I'm working to comply with local racing regulations, as well as making sure it's somewhat future proof.

Got a bit sidetracked by chopping off the exhaust - it's amazing how much upper RPM response is gained after removing this bottleneck. Putting together something simple to replace it.

I enjoy my HCP flash, but even after three revisions, flash alone doesn't touch the difference in power when running the JB4 as well.

Can I run these settings even though I've got an HCP stage 2 flash?

Steve @ BMS/Fuel-It! 11-09-2017 11:38 PM

I'd recommend starting with the defaults and adjusting as needed. PID
gain is a bit high.

Those are Protecon's settings...I've never adjusted duty bias, PID gain, etc. The ONLY things I've ever adjusted myself are Map 6 Boost (anything above 21 and I get overboost errors that take a while before they clear) and my FOL to 80 (per your advice, Steve). Anything beyond that I have truly no idea what I'm doing. I don't know at what point or even what it means to adjust duty bias, PID gains, etc. I considered flashing back to a stock tune just to try Protecon's settings to see how it'd feel, but then I'd get a CEL for no kitties.

Is there a "JB4 Settings for Dummies" page somewhere so I can educate myself? S63 support stopped shortly after I got the JB4 going, I've posted a few logs, only have really adjusted the FOL and then nothing has changed since, yet I feel like I've got this great tool that's not being utilized.
