Can someone take a look at my log.

Anything that comes out that might point to issues or looks all good?

Running stage 2 91 with 94 Octane pump gas

[BreakMyWallet]

Here are some logs I just took. Running the BMS BEF for Hybrids/PI/E85. I'm unsure of the ethanol content as I didn't measure, but it's a mix of about 9 gallons of FlexFuel and 9 gallons of 91. I actually topped off 4 gallons of FlexFuel after burning that much off of a 5:13 mix of FF/91oct ACN mix I had earlier.

Here's the earlier ones before I topped off with another 4 gallons of FF, when I still had the 5:13 mix of FF/91oct ACN. I'm a novice at interpreting logs, but I think the timing was being pulled compared to the above log due to the lower ethanol content.

I just upgraded my LPFP from a Walbro 450 to a 525 (running the EOS/Torqbyte BPM4, and wanted to test it. It did noticeably improve the pressures at redline/high boost. I think I might be able to run the FlexFuel straight from the pump without mixing. I'll try that next.

My setup is Pure Stage 2 high flows, PSP 900IC, VTT inlets, PI, freed up exhaust and intake. I have outlets to install and will upgrade to 3" piping from IC to TB next. I haven't walnut blasted yet and I'm sure it needs it. After I do that I plan to get a custom tune. Also have a Motiv FlexFuel setup to put in.

Here's the 2nd log. This one felt a little worse. The pull wasn't as strong and from the looks of it I had more corrections this run than last.

Stop going wide open or getting into any power until you fix your STFTs. Your bank 2 is dead lean(assming what the sensor is reading is right, which it most likely isnt) What codes do you have?

You should have a primary o2 sensor dead, replace both or all, don't beat on your car until its fixed.

I fixed the O2 sensor. It wasn't reading at all like you said. Code kept coming back, but now that I replaced bank 2 no more codes.

That was the run I did last night after O2 sensor install.

Was hoping to see if someone could give me a second opinion on whats going on here. Basically what is going on is while cruising at ~50-60mph, my car will almost "buck" or lose power for a moment before regaining its composure somewhat frequently driving home. It seems to be sporadic when it happens too. The crazy thing is that there is no engine codes what-so-ever.

Only mods are a DCI and that's about it.

My thought process is the dips in timing @ ~-5 deg is causing the dip in power.

I'm thinking that likely the culprit is vanos solenoids being dirty/clogged? or is this something with a bad o2 sensor causing it?

Any help would be greatly appreciated!

Reset all adaptations and pull another log with the car on cruise control near/at the speed where you notice issues.

Forgot to mention, all adaptations in MHD were reset a day prior to this log to try and clear out this issue.

I'll try and log it on cruise control though, if I do recall correctly, it does happen then as well.

Is there any other parameters I should be logging?

Here you go. I reset all adaptations again to be on the safe side.

Some more info I forgot to mention earlier:

new OEM bosch spark plugs ~5k ago
new OEM Bosch coils ~5k ago
new index 12 injectors @ 120k

Based on what i'm seeing there, the turbos look like they're building some boost and then cutting out? Maybe the boost solenoids potentially?

[Jwallace410]

Does anyone know what the numbers represent for MHD parameter "TQ Lim 1-3"? I had [number "4" show up on Tq Lim 1 & 3] and [1048 on Tq Lim 2]. I read that 1048 was a "code" but no explanation for what they mean. Im guessing they show power exceeding trans tq numbers, but dont know what the 4 and 1048 mean.
I do know theyre accompanied by dramatic cut in timing and power, usually happening on my car with anything over 50% throttle on a custom map.

Hoping xHP flash will help along with more custom work on the map.

Anyone wanna take a look at this log? I was hitting tq limits with Alpina style flash. These logs are about 100 miles after flashing xHP stage 3.

One thing I noticed is that I never get to 100% WGDC?

Your never really hitting target boost and getting mad throttle closures as well. Lambda looks like its never going to hit 234 either

What typically causes that?

Here are 3 more logs I pulled very early this morning. Car was at around 180° so not fully warmed up.

For the Lambda, if its both Bank 1 and Bank 2 and they don’t shoot up at same time could be indicative of leaking injectors in the corresponding bank

You should be logging both banks as well log STFT on both banks

Just did the N20 TMAP conversion and remapped. Going to fuel up and run a few logs tonight to see if it helps with the throttle dropping. 👌🏽

Mine did this a few days before one of the fuel injectors decided to take a dump.

You sure you want your WGDC pegged at 100% every pull ???

u DONT wanna see a 100% there

Good to know. Been hearing some conflicting info about WGDC lately. How's the log look otherwise? I need to graph a few more here soon. I did the N20 TMAP conversion and am running E50. 😁

Hey guys i was wondering if someone could take a look at this log i took. Im currently running MHD stage 2+ on 93 octane with a catless downpipe and an intercooler. I noticed on this log im not hitting anywhere near my target boost psi. I also was revving my car a little the other day and noticed when i let off the gas i could hear a slight flutter which i figured could be related to me not hitting target boost. Thanks

Hi, everyone,
please take a look at my logs, recently noticed short trim deviation greater than 13%

https://datazap.me/u/frankenfive/hug...23-24&mark=117

when I step off the accelerator pedal AFR sensor for Bank 1 is somewhat slower in reaction

Cant help but like what I read here from DAW.



This is a New Set of N54 Turbocharges & They Utilize A Full TD04L Bearing Housing Just Like RB Turbo & The Pure Turbo Stage 3. These Are Made Right Here In The USA & They Come With Every Upgraded Option You Can Possibly Do With No Added Cost While Still Maintaining The Highest Quality On The Market. How We're Able To Offer This Price Is Very Simple "We Manufactured & Machine Many Of These Parts In Large Volume To Get The Prices Down"





These Are Brand New Full TD04L Hybrid Turbochargers with a Garrett Style Gtx Forged Billet Compressor Wheels, TD04L Ultra High Flow 9 Blade Turbine Wheel & Upgraded Thrust Assembly. These Turbos Out Flow a Standard 17T Turbo & Are Good For Roughly 775+HP Depending On Your Mods.


Turbo Response is the Closet Setup To The Factory Turbos But With All The Added Benefits Of The TD04L Turbo. End Result Is The Broadest Power Band Possible With The Most Average Power Throughout The Full Power Band From Below 2000 Rpm Past 7000 Rpm



We Build & Balance These Turbos 100% In the USA Anyone Is Welcome To See Proof Of This.


These Turbos Are Very Similar To The RB Super Evos, Except We Use An Upgraded Thrust Assembly Free Of Charge, Custom Turbine Ring, No Cores Needed & Far Less Money..


We Aren't Playing The Manipulating Dyno Jet Games Like Most Of The Others Selling N54 Turbos "Their Numbers Are 100% Not Real World Or Remotely Close" If We Ran This Setup Right After The Others On The Same Dyno With The Same Settings You Will See Extremely Similar Peak Power Numbers But We Will Average More Power Throughout The full Power band.


We Do Have a Dyno at our Disposal Like The Mustang Dyno But We Let Real World Performance Speak For Itself. "For Instance At 19Lbs In a Full Weight 335i With Full Bolt-Ons We Stay Dead Even The Entire Way With The Dodge Hellcat From 40Mph To 140Mph On E30"


We Build These Turbos When Ordered But Most Of The Time We Have Them Built & In Stock.


Black 2000 Degree Ceramic Coating On The Exhaust Housing is Extra Please InquireCastings Are Brand New (No Core Charge) Brand New Factory BMW OEM Wastegate Actuators Ultra High Flow Forged Billet Compressor Wheels Parts Are 1st Component Balanced & Than VSR Balanced (Data Sheet Included)Custom Turbine RingThis is The Highest Flowing TD04L Turbine Wheel Available (9 Blade) Free High Performance Dual Oil Port Thrust Assembly Machined From Copper Bar Larger 2" Compressor Cover Inlet No Modifications needed to install (Except For 2" Silicone Inlets) Billet Wastegate Flapper Valve With Upgraded Stainless Rod Tune required! 3 Year Warranty!



Note... These Are Not A Modified TD03 Stock Bearing Housing With Smaller Coolant Ports To Except A Machined Down TD04L Turbine Shaft Which Uses a Turbine Ring & Bearing That Is 30% Smaller Than A True TD04L. That Is Fine For Some People But Not The Same As a Full TD04L Bearing Housing & Components.
