Did a few logs yesterday and I want to make sure everything is ok and to provide more info for those with MPPSK and are thinking about adding JB4. It was kinda warm out so not sure how that affected things. Everything is stock except the wheels. I'm running firmware 5e. I don't want the can flap function so I haven't updated to the latest. Are there any tuning advances to the new version?

[risktaker76]

What octane you running?

How's it feel? Hopefully I will get mine installed today and post logs also...

Ps also don't care for canflap also ... since someone stated the new version broke the ability to control the stock function for mppsk (i.e. Comfort closed ... sport and sport plus open).. waiting on confirmation how to get it back to oem function

Psss check your settings... log it says
N54 E Series

Should say
F Series All

Not sure if it affects anything

My feelings on the JB4 map1 is that you can definitely feel a difference whether in comfort or sport/sport+. It was pulling pretty good before but now it REALLY pulls. I'm using 93 octane fuel. I haven't tried any of the other maps and I don't know if I will for now. Don't see a need or feel there will be much difference. We gotta be at the fuel limit set in the DME by BMW or very close to it with MPPSK & JB4. I still haven't seen hard proof that MPPSK raises the fuel limit to be more than a 340/440 without.

[risktaker76]

You have the fuel control wires? (ie flexfuel wires) I ordered these to be able to control the fuel.. I guess we will see if it improves or degrades performance. Will compare with your logs when I get my first logs.

I'm no expert but looking at your logs comparing your 0 to your 3rd run it looks like your making 2 - 3psi of boost (as high as 20 - 30 hp)... that's great.. your trims look good.. afr slightly higher - almost no throttle closures... no major drops in timing.... to me your logs look good... lets see wht the experts say.

I'm with you also... I'm looking for the little extra... I probably wont try others maps except for logging...

PS - check your settings to ensure its logging properly - you have the wrong platform selected.

Your timing looks really good in Map 0, and pretty good in Map 1. AFR could be slightly smoother initially, but that's why mine look like too.

I prefer a flat 17.0 PSI Map 6 (for now), as I just don't like the way the DME ramps up and then ramps down like a triangle.

No I don't have the flex fuel wires and I checked my settings are on F series -all. There is no option for b58 or f30.

Thanks for taking a look.

[risktaker76]

Can you do me a favor...

Can you see what your sport gauges are reading?

After installing the jb4 in all maps my hp is Down Considerably

Map 0 struggles to pass 360 for example...

Before install I was hitting 375 easily

I know they don't mean much just want to see if it's normal with the jb installed.

Thanks

That setting is only for code reading. Not a big deal.

[Cruz28/40]

Terry@bms any thoughts on the logs?

[Steve @ BMS/Fuel-It!]

Why do you have PID Gain set to 0?

Map 1 looks normal at about 4psi above ECU PSI.

Thanks for taking a look and I didn't change any settings. Whatever default it was set on I let it at that since installation. I only updated to 5e firmware. Risktaker did alert me to what should be in the default settings as it says on the first post of the B48/B58 JB4 thread but nowhere does it tell you to make sure it's set up that way.

[Steve @ BMS/Fuel-It!]

There are other variables that can affect those settings, either way, make sure they are set to default and do another log.

[Bullitt1841]

I have noticed that I have different settings pull up on the app when I am in different maps. I never noticed this on my N54.

[risktaker76]

Yes! This is why I was asking if the Default Settings were Global or by Map...

Terry told me you set it once and is applied to all maps... but I also noticed they changed when I changed a map... Even for Map 0 they were different - it had values defined that were not defaults or 0s..

We need clarification on this point...

Oh I didn't know it might change and that you MIGHT need to set it for each map.

New logs.....much cooler for these pulls and a little damp out but with my Michelin Pilot 4S tires I made it work

Edit: almost forgot these logs are with Map 1 and I corrected the settings to the defaults as instructed. I plan to try Map 2 after I get the Eventuri intake and find the gas station that sells 98 octane gas.

[Steve @ BMS/Fuel-It!]

Some values are dynamic. In this case FF is dynamic on non-additive maps. What other values are you seeing change?

Your FF value is set to zero, default is 50.

Log looks normal to me.

[risktaker76]

None have changed for me...

But when I first received the jb4 maps 0 1 and 3 had different values from each other ... 1 had all 0... 3 all values where different and map 0 mostly had 0 with the exception of only a few... this is why I posted 4times in different areas if the defaults should be put in each map... when terry replied it's the same across I went to all and put in the default values for each map...

I admit I was on v4 firmware (what the board shipped with) and since upgraded...

[Steve @ BMS/Fuel-It!]

The user adjustments are the same for all maps as far as I know. the only exception to that is the N54 single turbo firmware.

[Cruz28/40]

Here are the updated Logs with version 8. I would also have the Eventuri B58 Intake but it doesn't fit autos only manual cars with B58
Can someone take a look and tell me how they look please?

[risktaker76]

They look great... Are you sure you have the MPPSK? Your boost is VERY low compared to mine - Albeit your timing is outstanding... From what I can see you can push it easily to map 3 or map 5...

Here is mine - stock car except for MPPSK/JB4 on 93 Octane.. My target is a mild 2psi above stock (which would be less then map1)

DME boost is fairly low but the target boost is correct at 4psi above ECU-psi. Ultimately you've got to get ECU-psi up or switch to a different map for more boost as it does seem pretty low, especially for PPK but this DME is finicky!

Lol, yes I'm sure I have MPPSK. Thanks for taking a look. I'm not sure how to read logs so I dunno what's going on in yours. Also not sure why boost is low. I have no other mods as I stated before my Eventuri intake didn't work out. I am using 96 octane fuel though.

Thanks for taking a look. I did a couple of pulls with map 3 (96 octane). The first one I had it in sport+ with manual shifting and did a 3rd gear pull. It didn't pull as hard as the second log I did which was sport mode letting the car do the shifting.

[Steve @ BMS/Fuel-It!]

Second log down shifted to 2nd gear instead of 3rd so that makes sense.
