    Why have you fitted a 4bar FPR???? the ecu will adapt it out again... there is no realistic reason to fit a 4bar FPR... and the only place to change it is in the actual map...

    you have logged your previous duty cycles to KNOW what they ran previously yea? BEFORE adding a 4bar fpr...

    ive done 10/15 logs ,lamba ect fuelling, boost, duty cycle, load, I have 10 dyno runs from midland vw as I went for a custom code map as I'm unaware of my current map but he advised low compression and 10 percent turbo so he was right actuator and low compression so all fixed and pcv delete -10 lamba at 6000rpm???? Idle hunts very slightly pistons were black withsootwhen replaced rings had only done8000 miles on them well say 10000!!??spark plugs brown pump pressure ok!!when I bent rod spark plugs were white!!I appreciate any help bill ive spent a lot more than I can afford at the Moment and was told by the chap at midland vw Jodie, there wasn't much at all he could do for me on map side anyway car was ok on dyno puling air, fuel, spot on boost was a tad low and he said low compression/worn rings in turn he was correct too give him his due!!

    a custom map is what I thought so I have been told by a tunning company there's not much more he could do so what is a custom map going too do for me??? I'm seeing max boost requested for a k04 hybrid at low rpm ie 25000rpm we both now they won't do that!!! im getting too much fuel so for 350 pounds what I'm I going too gain no power!!!! Egts are ok inlet temps good,so I can't justify that money at the Minuit that's why I'm asking for help what's your opinion?? Water meth manifold then a custom map for me!!, i will be using u and bill you have my word you are both very helpful hear on ther forum so out of exsperienced and loyalty for all the help but as for now I'm just want too turn my fuel down a tad even with 3 bar reg I'm seeing -10 at 6000rpm cfs are 3, bump timing up 1.5 and cfs are 6 only. On high rpm do I See any cfs , after 5600rpm my vvt was dodgy then ill do my logs with both regulators today and post results if you told me I have a stage 1 map I'd happily pay 350 but I've already been told its a good map??

    Just because the tuning company you have used say they can't do anything else doesn't mean somebody else can't mate... no need to name the company here but I have personally seen maps from reputable tuning companies that quite frankly are awful...

    Dunno where you are based but I would personally say book it in with Bill as I know for a fact he has loads of experience with this setup and mapping hybrids... even if you just get booked in for a health check initially at least he will be able to tell you whats going on...

    who told you the map was good? the people who installed it? << see where I'm going with this?

    If its fueling incorrectly, and by that I mean not doing whats its told OR its doing what its told and thats just being told incorrectly??

    Lobbing in a 4bar regulator will bump up fuel delivery around 15%, so you would look to adjust this down with unisettings etc OR via the map.. The reason however why you Need to bump up fuel delivery 15% is my question. If the maps been declared "ok" then why would you want to add more fuel. Most common reason to want to up the fpr is to gain more fuel from the injectors as they may be maxing out their duty cycles.. (block 002) Was This the Case with you?

    Aribtrarily adding a 4bar fpr will make the pump work harder.. It has to produce 4bar + boost pressure fuel delivery. Tired pumps can often delivery Less... so be aware of this.

    There may be issues you are unaware of which is causing you to have fuel trim issues.. Leaks.. etc... Has it been smoke tested to see? Very Very revealing test. (I do it all the time)

    I dont recall all your previous logs.. but if requested boost (whatever it was) is being met (and not 2550mb), airflows, CF and fueling are all there then it may help spot something. post them below (so in a single thread and not scattered over ASN)

    You may have hardware issue, and equally software issue on this "custom map".... It happens.

    Please start using punctuation properly. Your posts are really hard to follow because there's zero structure or punctuation to them, and it makes them difficult to read or understand. Putting a little more effort into writing the posts would probably get you more help and faster.

    I'm also kind of confused as to what you're actually trying to fix/achieve. It comes across that you don't seem to understand the complexity of how engine management works and what effects it's operation. It also seem as if you're maybe a little confused/mislead as to what you're wanting to achieve from the management. Sorry if that's not right, but it's how it's come across.


    There's a few questions that answering would help us all understand the issue a little more:

    What's the history of your engine?
    What spec was it when your current map was put on it?
    What's changed about the spec since then?

    I dont recall all your previous logs.. but if requested boost (whatever it was) is being met (and not 2550mb), airflows, CF and fueling are all there then it may help spot something. post them below (so in a single thread and not scattered over ASN)

    You may have hardware issue, and equally software issue on this "custom map".... It happens.

    So you have put a 4bar fpr in to add 15% more fuel, then the car is removing 13% of that, and for some random reason( s=despite you saying fueling is ok) you want to add 5% more fuel with unisettings??

    And you would gain from a custom map as it'd have all the the load settings and interventions adjusted, also the timing and fueling will be adjusted to suit the car based upon many things making sure its as good at idle as it is at WOT, which is something a generic map won't have

    no I want to remove fuel so I want to remove 13%not add!!my idle was 720rpm I can raise this in unisettings but not sure on fuelling ?primary fuel -how many??you say percent so I take away how much?? I'd rather some one explain than me do and log ect as I don't have a dyno lol!!my fuel is ok in logs as you say too much???

    222grams is about 270bhp.

    From those logs its pretty poor to be honest!

    You Definately don't need a 4 bar fpr

    it needs proper mapping! Unless its got a funny clipped stock turbine hybrid there's no reason why it shouldn't perform better.

    Well if you want to remove fuel, before you mess with Uni-settings. Fit a 3bar fuel pressure regulator back in and see what the fuel trims are like then.

    it is a standard clipped turbine not stage4 spec!!221gs at 6000rpm is poor???i am not hitting my requested boost still in 2nd 3rd gears it rises the higher the gear???pcv delete venting too atmosphere??my clutch started slipping in 5th and 6th gears and I get the pull and boost I got before engine blew but can't seen too get it in 3rd more actuator preload???or is it my n75 I'm going too fit a boost controller ???

    yes I think I will put my 3 bar reg in tmorrow turn up the boost too we're it use too go if I can with some more preload and see how I go!! If not I'm back too the boost creep!!!!

    Adding a 4bar FPR adds around 15% fuel as Mark has already said... why don't you just go back to the 3bar FPR and then thats fixed... assuming you haven't changed the injectors you can't just do this kind of thing on ME7 as it will adapt it back out again anyway... you will prob find LTFT's will head towards -15% anyway after a while as the ECU adapts...

    Fitting a 4bar turns the std 370cc injector into just over 420cc injectors (theoretically) but the map will still be setup for 370 cc... using unisettings isn't tuning dude, its a sticky plaster... I use unisettings to make global changes, log then adjust the map to dial the injectors in... the map has several other maps that need tweaking to get fuelling right too...

    In unisettings in you need to take 13% fuel out then you do just that in primary and secondary but in all honesty its not a method I can recommend considering the the current unknown state of you setup... you have a hybrid that probably capable of 300hp on an unknown map on std injectors...

    13% fuel adjustments is well within the ECU adaption range but if it was doing that on anyone else's car it would be classed as a problem... LTFT's in block 032 is where you need to look... don't look at lambda adjust in block 001 too much at this time as you need to get base fuelling right and sorry to say but proper mapping is what you need...

    Your logs are not very clean runs so its tricky to see whats actually going on... a proper logging run will be 2k rpm to redline in third gear foot to the floor... there is normally enough resolution in a run like that to get an idea of whats going on...

    Whats block 032 saying?

    If you are not hitting requested boost then thats a hardware issue... actuator preload maybe the issue but don't over do it plus all hybrids I have ever work with need a stronger actuator anyway... typical preload is 3 turns from where the gate is held shut...

    No need for a boost controller at all... the map you have isn't asking for loads of boost tbh and its not the N75 thats the issue I don't think...

    TBH I don't think there is much more that can be done over a forum... if you are sure you hardware is setup ok and your 'map' is ok then you are missing something somewhere and ideally need to get it to someone that knows these engines inside out... if your previous tuner couldn't find the issue then I would suggest taking it elsewhere...

    Go to bill @ badger 5 or niki @ r tech and get a custom map...... From reading your thread it's got to be worth it's weight in gold to you????? You will know what map you have and your car will be running how it should !

    0.8 STFT's is nothing.. -10 LTFT's is the ECU adapting out your 4bar... swap it back as you said to the 3bar, do a fault code clear in VCDS (even if there are no fault codes) as this will reset fuel trims... make sure any unisettings to do with fuel you may have adjusted are back to defaults and run it a few days to see where fuel trims land...

    N75 duty is difficult to say on the logs you have... seen an 88 in there... most maps are capped at 95%... would expect to see this a little lower if the actuator was 0.8bar as it should be on a hybrid... stiffer actuator will give more duty cycle head room...

    I'm no officianado mate but it seems to me that you know a little about what you are talking about, but not a lot about what you are talking about......lol And if you have a car running all them mods with an unknown map and then some mush in the garage at the corner of the road saying everything's ok that wouldn't be good enough to me...... I would be taking it to someone to give if a full health check to make sure everything is running as it should.... My own personal opinion...

    it does look to be achieving requested boost when it see's sufficient load.. and has plenty left in the n75% to do more..
    the airflows are meh... but its only a stage 2, so dont expect to get big numbers from that spec.. Hardly more than a stock k04.


    forget boost controller.. get it mapped properly once you have fixed the known issues, and then take it to a specilast who may find you have other issues you dont know about. it will save you angst and money overall I imagine.

    yep, slipping clutch will drop load on engine

    clutch slip i would expect in higher gears not 1st however..

    Get it on a dyno dude... an hour of Bill's time will probably answer all these questions.... until you can say for sure that you have no hardware issues you are going to be chasing your tail on this.. trust me I have been there on more than one occasion... its getting impossible to help diagnose the issues you are having without knowing for sure that your hardware setup is working as it should...

    The map is requesting the boost and the hardware is not making it by the looks... there could be any number of reasons this is happening including air leaks, incorrectly set actuator or even a damaged turbo...

    load! + "unknown" map

    get it looked at by someone who knows fella.... Dyno, logged, smoke tested etc etc etc All that has been already suggested

    I cant add anymore than already said...

    you are just poking and hoping otherwise

    FIX YOUR CLUTCH before proceeding.. No one can tune a car with slipping clutch = pointless
