N55 E-tune progress

I went back to the stock oem box intake with k&n intake filter and noticed that my tps act.% did not have a spiked drop, throttle closure.
Have a look at that when you log with different intakes.

I haven't posted any progress as of late and thought I would give my updates in this thread since there is good information here.

I had to ditch the Cobb AP and now running a JB4 e30/e40 mix.

Why I ditched the cobb and PTF tune.

I was having issue with the car going into major limp mode and would be very random. This limp mode when under WOT felt like the brakes coming on, like hitting a wall, not a good feeling for sure.

I would load the PTF map and all would seem ok for about a day (I did have this issue running any cobb map over stage 2 as well). The car sometimes at throttle tip in or WOT would go into a limp mode where I would have no power but car would stay at idle. Probably a safety thing to keep brakes and steering active. Absolutely zero throttle. Turning the ignition off then on again the car would run fine until the next time.

PTF asked me to capture logs, but I could not get the issue to happen when logging. I could run 3rd gear logs and they looked good.

After this happening on the freeway a couple of times which put me into some very unsafe situations I uninstalled the cobb AP and went JB4.

Once the JB4 was installed I ran the BEF from JB4. Everything ran fine but again started getting some misfire and bogging issues under throttle. No limp mode as I would back off the throttle.

Uninstalled the Cobb AP and now running the JB4 with e30/e40 mix and no issues, not one. I do need to get some logs running the e85 mix but it runs great.

which BEF were you running, pump or e85?

I was running the pump BEF as I wasn't using e85 until later.

Thinking back it may have been an issue that I was running the AP for monitoring, which I understand may conflict with the JB4.

Which map are you running with the JB4, map 5, autotuning?

Yep, map 5.

Hit,

That's crazy - I've had more or less the same experience so far wtih my cobb and the BMS BEF. My car has always taken to the Jb4 + map 5 / E40 with NO problems. I threw the BMS BEF on it and the car started to misfire, stutter and even go half engine lights.

I'm under the assumption it must be setting related.. I was running the E40 flash

I thought that the BMS BEF's are strictly for use with N54 engines not N55's with DCT.?.?

[Mernardi]

There are high load BEFs for N55s. They are technically for larger turbos than stock, but can run with the stock turbo. I personally run JB4 + pump BEF and use map 5. I tried the E85 BEF and it did not agree with my car; misfires and such.

As for the PTF maps, I captured the misfire/limp issues on multiple logs. They were never able to figure it out, and obviously still can not. With the success people have with the JB4, I do not see any reason to protune an N55. My Cobb will be used strictly for BEFs.

I have had issues running with both tuners in one way or another. I currently am running a Cobb with ptf and just got an updated map that seems to be working very well so far. Very smooth, no tps dips. I love the high yielding consistent boost compared to map 5 on the jb4. Map 5 just didn't do it for me.

Ptf pump or e50 flash?

For those of you running the bms BEF. Don't forget that the BEF is only for jb4 ISO. Also, if you are running the latest jb4 firmware, you need to select setting 4,2. This was not required with some of the older firmwares.

When running the jb4, I run the pump BEF with 91 or e50.

Ptf 93 octane. I don't want to mess with e85 anymore unless its 100% e85.

[Everfly]

I have the same issue with E50 map on Cobb. JB4 never have any problem even E65

Nice. Ptf unleaded fuel flashes are solid

Then I gave up on pro tune and installed a JB4.

Well that might explain my issue. I am non-ISO jb4.

I am considering going ISO but any reasons or side effects of going ISO?

This is why I wanna get rid of my Cobb AP and not even bother going the PTF route.

Just get a jb4 and be done with it.

[houtan]

just checking in to see if anyone has updates on their N55 ptf etunes. especially ethanol blends.

I have a new e50 map to try out but haven't had a chance to pull my jb4 to test it.

[houtan]

bump. anyone have new experiences with their PTF etunes? Please post your results and experiences.

[tglazed]

I had a ptf tune done on my n54 135i, it was awesome and car ran like a champ. Not to mention that they were always willing to keep perfecting the map. It took about 7 maps to get it perfected then I would still send them logs every once in a while and they would adjust a thing or two and send it back. Car ran awesome on it. I plan to go the same route with my n55 135i

[houtan]

I have the same experience. They are always willing to make adjustments. Looking forward to seeing your results.

I'm running an E50 blend. Been getting fuel cuts at WOT at the top of 2nd and 3rd. Haven't had a revision yet that solves it.

Getting frustrated at this point.
