Just finished installing inlets and outlets, car is now true FBO, stock turbos, 91, stage 2+. XHP stage 2

At WOT, near redline the car goes into limp mode, I’m guessing it’s a fueling issue.

Code 29DC - DME: Cylinder injection cutout. Always comes up

Code 2C7B - DME: Oxygen sensor after catalytic converter: Signal. Sometimes comes up.

The car pulls strong when it gets into boost but then it falls on its face.

Have had 2AAF - DME: Fuel pump, plausibility. Since I bought the car a few years back. Bought it at 198K, now at 206K

Thank you guys

First log is the pull
Second is how it idles horribly when I pull over to the side of the road

Looks like your HPFP is toast. It drops down to 3xx psi when it should always be over 1,500 at WOT.

Get a new lpfp and hpfp and u are good to go

Hey guys its me again!
After the experience i have since changed the LPFP , did walnut blasting , changed the chain guide rails (aparently afew pieces of the plastic broke due to high milleage).

Have currently flashed stage 1+ 93 oct will attach the log below , still has some timing pulls but nothing above 3 on average , need more experienced guidance if the tune is fine! Turned off burbles too

Ps: i did get a 2D2E throttle valve angle-intake manifold vacuum corelation code, searched online and alot are pointing towards it being a false alarm, but some advice on this will be greatly appreciated too
Edit: from my logs it seemed the 2D2E came when i temporarily went over boost target so dme tried to compensate by closing throttle? I think that is normal yes as long as it doesnt happen too often?

vadonchez hey bro greatly appreciate your advice too if you are free could you take a look at this log

A french N54 owner on french Z3/Z4 forum had the same error code than you (2D2E) and it found that the VC was cracked. he didn't change parts yet so har to say if it solved the error code but take a look at your VC.

Your log is ok to me everything looks good on fuel side.Everything looks good on boost side too.
But timing corrections on all cylinders as if you are using bad fuel.
Did you try to run 91 octane map with 93 octane fuel?

And again, try V7 2+ map as they are demanding less timing @low rpm than V10 wich can help in your case.

Hey man thanks for the input , sure ill give v7 a try ill let u know the results!

As for the 2D2E code , i cleared it that day and it didnt came up ever again, think it was just a freak accident or something , anyways what is VC?

[vadonchez]

Your Valve cover

Awesome ill get it checked out , thanks for the recommendation gonna go flash 7.1 now and give it a log , ill get the valve cover checked too just to be safe , but the 2D2E code hasnt came back since that 1 time

Fairly terrible. You have lots of timing corrections and the throttle is sat at 50% the entire pull because you are probably (why not log boost target) overboosting.

My man , thank you so much , v7.1 stage 2+ 91 oct worked wonders , close to 0 timing pulls , all looks fine too

stage2+ v7.1 91oct

[vadonchez]

Ok cool.
Now you Can try with 93 octane !

Because pedal position is low.too.
I think je just not wot totaly but if you look at his other logs that's better.

Pedal position is at 99% the entire time.

We are not talking about same log, i talk about E92335ISG log

Hey man did another log for you! Gear 4 WOT now! I would suggest showing throttle position too , a short while after WOT timing pulls all dropped to 0 , im assuming thats a good sign and timing pulls just normally cruising before wot is normal , think the massive timing pull could be due to fake noise as i downgeared with burbles before pulling so that section can be ignored? If im wrong could correct me too! Lmk!

stg 2+ v7.1

[vadonchez]

that log is ok to me, some timing @low load but mhd say that's ok so...

Try to do a log up to 6000/6200 rpm next time.

Enjoy!

Hello fellow car friends.

I just replaced my turbos with bigger twins, installed a 3.5 tmap sensor and deleted the vac. canisters. I test drove the car after the install and at wot the boost solenoid doesnt want to close the wastegate. The only codes I have right now is that my Fan is not connected to my car because its currently not installed. I hope yall can help me with this problem...

PS(no timing corrections, hpfp value is at 1850 on wot, lpfp always at 80, throttle body also doesnt really want to open at 99% pedal position)

I hope yall have a great day.

You'll need to connect the fan otherwise the engine will be in limp mode, hence the lack of power.

Help with this log please. New boost solenoids fitted and now the car is surging.

Odd! Did you get Pierburg solenoids? lines mixed up somehow? Not sure if thats even possible tbh.

How was it acting before?

It ran fine before but cut power if the boost went too high. It looks like it's doing the same but instead of cutting power it just drops the boost down.

I got the maxgear solenoids from Autodoc.

I'll put it on the stock map and see if that changes anything.
