Having Wedge "pro-tuning" my car at the moment, which I specified for moderate timing advance and boost level for reliably performance when I go tracking on road courses. But from the look of the logs I did, look like BMS pump flash is still a better match for my car and E30 fuel (see my sig for mods)

BMS_pump+93pump+e30+map5: http://datazap.me/u/cloud9blue/bmsma...29&zoom=61-107

Sent the logs over to Wedge on Monday night explaining the issues that I have with latest version of his flash, still waiting for a response from him

Just too bad PTF doesn't tune backend flash for JB4...

If Wedge is your tuner and he's still revising your map, it's a work in progress and it's in somewhat poor taste to immediately post logs and decry judgement.

Many initial maps are sub-optimal. I don't know about Wedge as a tuner except for what I've seen on the forums, which I take with a grain of salt, but yeah, let the dude do his thing. When he's done if you don't like his map, post up, find another tuner, etc.

i definitely agree .
That being said so far the logs look clean , wedge maps are very aggressive but looking at your logs there are no timing corrections which is always a good thing.

10 out of 10 Wedges Flashes are far better then anything out there and the flash alone pulls strong.
a couple of things you should check is

is the JB4 set-up properly
Did you do a few learning runs before you took the log


as a side not the boost should be a little higher in map 5 you should be peaking in the 17 range and I didn't see that at all
I would recheck settings what ISO are you running

JB4 is set-up correctly. have been installing JB since days of JB3.

Yes, I typically do 2-3 pulls from 3rd gear to 4th gear before logging.

Latest ISO 28 with individual cylinder logging. What could the reason be? Ambient temperature is around 70F. I actually have seen16-17 psi after running through a tank of E30 at the track. but to be honest I have no interest in running the stock turbo at boost higher than 15psi.

Perhaps the tone of my first post was a little negative, but I am here to seek advice on which flash is the best running one at the moment.

I have another track day coming up this weekend (I typically run map0 to 1 on track to preserve the turbo). But as I mentioned I have been waiting for a response from Wedge for the past 3 days, so I need the help of the forum to see which map works best for the moment. Not sure how is that poor taste on my behalf...but thanks anyway.

[09BMW335i]

Just for shits and giggles try going back to 27_12 and do some logs and see what you get.

I am running one of wedges flashes and Map 3 with a max PSI of 19. I run around 35-45 % E85 I am hitting max boosts of 17-18

Have you posted this question on BMS forum and other bmw tuning forum? BMS forum is the best place to go for advice on stacking JB4+back end flash.

[09BMW335i]

cloud check your PM

Wedge flashes are good for 1 gear and as soon as you shift they fall on their face. Post shift timing on wedge flashes are horrible. Cylinder 1 is a joke and if you log all 6 you'll see. I've raced 5 wedge cars and destroyed all of them. They all quickly went back to BMS maps. It's better to have all cylinders at 11* than have 3 at 14* and 3 at 6-8*. Terrible flash and if anyone that has a brain and knows how to log all 6 cylinders will realize that.

[tc535i]

would somebody mind shooting me a PM? Don't want to thread jack, but it seems like there's some informed people in here that could help suggest a flash setup for my car... appreciate it

I did actually, but the guys at BMS had problems reading the csv files. Not sure what the problem is exactly, since I can read them just fine on my side.

I agree with the fact single cylinder logging is no good. Was using BMS pump flash for almost 1/2 year now, but the reason I decided to give Wedge a try is because the post-shift flat-lining that I had after I put on DP and FMIC last month. Note, I specifically asked for non-aggressive timing w/ Wedge, but seems like the map was not adjusted accordingly. As you can see from the logs, timing was all over the place w/ Wedge's flash. Also noted was the throttle response was way too touchy even w/ linear throttle map, which is fun for street driving but hell of annoying if I decide to use this map for the track.

Funny thing is that after I switched back to the BMS pump flash, the timing flatline seems to mostly disappeared.

Those timing flatline because you may have multiple timing drops during the one gear. When you shifted the DME pulled your timing to protect the engine. The new 6 cylinder logging will show you that.

lol, so anyone actually read the logs I posted?

From my basic understanding of N54 tuning, the ECU flash sets the base timing table, which is then adjusted accordingly base on the operating condition of the engine (IAT, octane, etc.) base on the knock sensors. If my understanding is correct, at the very least, map 0 / stock boost should demonstrate the targeted degrees for the timing advance (since the engine is operating under the least demanding condition).

If you look at my log for map 0 again, timing is all over the place between 12-14, which suggests that the ECU is targeting timing advance that is at least above 14 degree, way too aggressive for pump fuel even for stock boost level.

Here is log w/ Wedge flash in map 5 running 93 pump, you can see that the timing is again way too aggressive. http://datazap.me/u/cloud9blue/map59...2&zoom=288-346

Btw, if you look again at map5 e30 log, there is some pretty noticeable timing pull around 5300 rpm in 3rd gear. Considering 4000-6000 rpm is where the engine spent 80% of its time at on track, it is pretty hard to consider this is healthy. Not sure if you ever read my log carefully, but I don't think anyone would call this a clean log I suspect cylinder 2-5 might be even worse off if I didn't forget to turn on the individual cylinder logging that day.

The only I don't understand why Wedge is giving me such aggressive flash while I made it really clear to him I want reliability and sub-10 timing advance.

because butt dyno is where the money at. lol just kidding. Yeah. more than 10degree timing is pushing it on pump gas.

I already stated that it is aggressive.
That being said ignition 2-6 showed 0 and assumed you have set CPS to 4 which gives you correction ( 0 correction is very good).
Now that u said it was off then that is a completely different story.
u should have mentioned that when you asked us to look at your logs
I recommend setting CPs to show correction on Cylinder 2-6 to get a better idea of how the car is reacting to the flash.

The log clearly says ign instead of KR...

[Msport335]

what could cause a drop in timing during WOT but no timing corrections?

No definitive answer on it yet ( most people say it could be traction,IAT,etc...) but it happens even on Cobb.

Not sure what you mean.
I select CPS 4 on my JB4 and it still says ign but shows me the correction.
