440 MPPSK - Map 6 Logs - N54Tech.com

risktaker76 · 06:59 AM

440 MPPSK
FF wires installed
FOL 0
EWG - NOT installed (just no time)

Been playing with Map 6...
All defaults set (except for FOL)
Flat 17 psi

Would like an expert to provide some feedback. What I am noticing

1. Timing is flat 0
2. Very smooth
3. Doesnt feel as much umph as Map 1 or even Map 3 but I can see its not allowing boost to go above 17ish... Maps 1 and 3 will boost up to 20 momentarily...

I am wondering if a some type of boost curve would be better
Such as higher boost at lower RPM 19 psi then actually lower it down to 16 as RPM gain... Im curious about this strategy.

Any other feedback welcome..

How does timing look if you target less boost or add more octane?

risktaker76 · 06-21-2017, 12:06 PM

I tried 15psi and the car was a pig...

I'm running 93 octane from Shell.

I will try 16psi to see if timing improves some

Terry @ BMS · 06-21-2017, 02:46 PM

I'd run map6 with 1 or 2psi over stock as an additive map, and call it a day. You're already running a lot of boost for the fuel quality.

risktaker76 · 06-21-2017, 03:21 PM

Interesting...I will try that and post a log

Here is MAP 6 Flat 2.0 PSI.... Runs very smooth... I had only 10 minutes of driving and seems it was still learning.. after this run I could feel a tad more powering down low actually.. I will post another.

I have included ALL maps I have tried if anyone is interested..

So far most stable, smoothest with best performance is
Map 3
Map 6 with 2 PSI flat (better than Map3 in the smoothness category)

Map 6 with 17 does not pull as much as 2PSI flat which I will attribute to 93 octane just not being good enough..

Take note the DME BT is tracking perfectly - Does this have an affect?

As always... Logg.. Then Logg some more!

Honestly I think your burning a hole in your stomach with the settings. The car has a fueling limit with or without mppsk. Either stay map 3 or map 6. At this point you have to accept the car as is. The more you turn up boost w/ lack of fuel the more it will result in choppyness and timing pull. Boost target will never hit as well. If you honestly want more power than you need to invest in WMI. Not only will you make more power but the car will be much happier at the boost your targeting. I love my jb4&BMS WMI kit. Transformed the car.

risktaker76 · 06-22-2017, 07:35 AM

I hear ya... I knew that the JB4 with the MPPSK it would yield small gains... right now just trying to get it as smooth or predictable as possible. Map 3 is the best map without tweaking - but unpredictable in smoothness... I think I can get Map 6 tweaked enough to get it smooth yet more power (albeit small)...

I would do Meth but its a leased car and just too much effort/cost vs risk...

Im nearing the end of tuning...

I hope sharing of all these logs provides MPPSK owners a leg up on tuning - or even for BMS to tweak the JB4 for those who have MPPSK cars - Maybe a MPPSK map.

I've had meth on my lease for 13k miles. It's cheap and easily removable

Terry @ BMS · 06-22-2017, 09:31 AM

Of the logs I thought map3 looks like it should be working best for you. I'd just stick with that and enjoy the car.

risktaker76 · 06-23-2017, 05:25 AM

Thanks.. I will look into the install and may seek your advice some more..

It's very simple and if your handy you can complete it yourself. If you need any advice you can pm me.

risktaker76 · 06-23-2017, 05:36 AM

Terry.. Your right... As you can see did another run today and honestly drove like a champ - but Map 3 definitely has more pull..

The issues I am having are inconsistency on Maps 3 or Maps 1... One day the car drives like a champ... in the next few moments its falling apart under WOT (not just bumpy but clearly loss of power). Of course most of my logs look pretty good however they just dont tell the whole story. I have settled on using the same grade , brand even station of gas to keep it consistent... My Av Ig Ret. is always a consistent 3 - 4 thus I cant believe its timing at this point..

I have not installed the EWG yet (just no time at this point). I hear from many it will make it more consistent - is that your judgement too?

One other note - It seems Map 6 with 17 psi target was butter smooth - Hit the 17 psi mark but didnt seem as much power - e Now at 2 PSI additive its also driving very smooth... Does Map 6 do something different than Maps 3 or 1 outside of Boost?

Also one other note, and dont know if its a bug - I tried 2.5 but it would not save at 2.5 and would only set at 2.6. The car also did not drive well - again inconsistency and went back to 2.0... thus this next log

Im close to the end of me bothering the community with all these logs..

I guess next steps is Dyno Map 0, Map 3 and Map 6 - do that when I get back from vacation...

My engine "resets" its timing occasionally to 0 or negative, and also increases its factory boost target. You can see this with an external OBD2 reader and the Torque app. I think it might do it each time I fill up. After a few pulls, boost drops and timing increases.

I took the JB4 off for my first dealer visit and I'm rolling around right now with just the Torque app for live viewing. Logging is a pain in the ass with it, so I don't log.

I'm telling you, if you install the EWG wires and run a 16 or 17 PSI Map 6, your boost will look so much better. I still avoid Maps 1-3 like the plague.

risktaker76 · 06-24-2017, 04:50 AM

I can't catch a break with this weather to get the wires installed...

Raining again!!

Map 17psi flat is fantastic (hitting 17 most of the time but all the time above 16)...but my average ign retard is showing 7... timing is flat 0 under wot...

It's butter smooth also..very consistent. The car felt weird actually..

The butt dyno though didn't feel as much. Almost like I lost

2psi adaptive butt dyno feels not bad but again inconsistency is back... also some odd shifting is going on. I will watch out for that.

Since upgrading to Hex 8 I went back to Map 6 2 PSI... See above logs - wasn't smooth...

Wow... Hex 8 is a HUGE improvement... As you can see y Boost is solid, smooth and my timing is excellent!...

Bullitt1841 · 07-11-2017, 09:13 PM

This log looks great. Everything is doing what it should and looks like it feels smooth.

Can you change the FUD bits value so you enable 6-cylinder logging? I use a value of 64. Then try a log in 4th gear. 3rd gear is a little more forgiving on the timing

risktaker76 · 07-12-2017, 05:14 AM

I added 3, 4, and 5 gears (fell off on 5th gear though was already at 130mph) and added all logging for ignition..

And this is interesting... First time I am logging with more than Ing1...

Ing1 is just about flat where all other cylinders are normal.. Nothing changed from my previous post today - even same tank of gas. look at the other cylinders... they have great timing...

And the car is driving like a champ! And honestly I watch Ing1 in real time on the screen (though at high speed I am looking forward) -

I wonder if there is a logging issue because I have it displaying on the screen

Does this make sense? Any ideas?

risktaker76 · 07-13-2017, 05:50 AM

More logs...

Its very clear - Timing on this car is all over the place. This is within 8 hours - again same tank of gas - no changes what so ever...

There is no way its octane alone but more the car I am more convincted... This sucks...

I filled up at a different gas station this morning... I will see later if it resulted in any timing improvement. If not, I will try E85 next and post logs.

HOWEVER, Boost looks fantastic! I must ask the experts - If timing is so bad, why does boost look so good?

Bullitt1841 · 07-13-2017, 07:29 AM

What I have noticed with the B58 is that the DME BT changes ALLLLLL the time, even during the same pull in the same gear. This will have a direct effect on the timing. It's pretty annoying.

Have you tried running my exact settings for a fixed Map 6 yet? The additive boost settings are always dependent on the DME BT. Therefore your timing will not be consistent.

risktaker76 · 07-13-2017, 10:01 AM

Not with Hex 8...

The last time I ran Map 6 with 17psi defined boost was solid at 17 - however same issue with timing - completely flat. I was also having some odd shifting behavior.. I switched back to Map 3 (now map1).

I will try however 17PSI flat with Hex 8 and see if anything changes..

I just filled up though - may throw things off again.

Bullitt1841 · 07-13-2017, 11:57 AM

Do a few pulls with 17 PSI Map 6 to let the timing and other things learn. I think you'll be happy.

risktaker76 · 07-14-2017, 08:19 AM

Instead of 17 flat.. I did 17 flat till 5000 where i change it to 16 flat to see if I can gain some timing..

Did a few pulls... Whats most interesting and very consistent (or inconsistent i guess) is Ign1 Is randomly low - more often than not but still random as some times its fine.

Can anyone add insight as to why Ign1 is so much lower than the rest of the cylinders? Again - no drivability issues at this point.

If we compare Flat 17 /16 with Additive 2 - It looks like Additive 2 is better with boost but FLat 17 is better with timing... Additive 2 timing though low is tighter across the cylinders. Hard to say without a dyno... But Butt dyno says additive 2 is stronger and maybe even smoother.. but I have not ran enough on the flat 17/16 enough

Insight always welcome...

Bullitt1841 · 07-15-2017, 10:53 AM

My Ign 1 does the same exact thing. Terry said he hadn't seen that, as of a few months ago. I would be really curious to see if others are having that issue.

On those two logs, your boost is targeting a higher amount at all RPM's with the additive map. You will definitely feel more torque that way. I think you could try 17 PSI all the way, or even 18 PSI tapering to 17 PSI.

risktaker76 · 07-17-2017, 06:31 AM

Took a log this morning with the suggest settings... I Start at 18, taper to 17, then down to 16 at peak RPM...

My FF has not learned down though..

My timing is fairly lower..

Terry - Any comments on Ign1 being 0?

Here is some good info (albeit not confirmed) on Timing vs Boost...
