    and, i think the fact you are now over maxing the injectors by 26% is in a way awesome, and shows what can be achieved with the setup you've got. i think its fair to say you've accomplished your goal already.
    i just hope for you, and other people that follow this route that its reliable.

    Thanks guys that makes sense. Only thing to bear in mind is that will a 4 bar FPR give me enough of an increase through my injectors. I think uprating the FPR is the easiest way forward as like Bill mentioned, the ECU is used to a 386cc injector so If I start plopping in bigger injectors it might become a bit more messy.

    My fuel pump is brand new so should cope with the 4 bar FPR fine and if I need to I can always run an inline pump to compensate but that will be another couple of hundred squid.

    I'll go and do this log in a bit and see what Bill thinks. If a FPR will make much difference then I can get hold of one of those easily and it's a 5 min job to change.

    ^keep what bill said in mind though, it might not be as simple as putting one in, well, it wont. so probably best you experiment with a fpr when you go and see him.

    it will be good for you (cheaper and easier) if the 4bar reg works. im guessing you want to avoid the cost of a custom map?? so injectors are kind of out of the question.

    I've got a 4 bar reg that won't be needed once I'm mapped and only done a few thousand miles, paid £45 for it but will sort something out if you want matey ;)

    Only a 5min job to do as well

    Only downside is dont think will have it ready for as soon as you need it :(

    Yes mate, trying to avoid custom map really as it wont be worth the cost. Would be nice to just have this running as quick and as stable as I can get it.

    Anyway here's the log data Bill requested. Did 3 runs:

    more fuel pressure = more fuel for the same injector open time...
    4bar add's ~15% more fueling


    I see from the logs its already adding 10-20% fueling to achieve lambda..........
    afr on revo are richer than I set them on my custom maps... I never ask for 0.7x lambdas

    as an experiment worth getting hold of a 3.5 or 4bar fpr and dropping it in and see what the adaptions make of it.
    whats block 032 sat at currently?

    Ok cheers Bill I'll try and get hold of an FPR to test. I'll check block 032 later, what does that block show?

    From those logs am I ok to drive this car hard or should I be taking it easy?

    This is a value that changes as you drive isn't it? So I just need to read it, I don't need to do a run to get results?

    actual fueling is ok.. 031..
    we now know that the ecu is using its adaption abilities to achieve this, and the injectors being max'd is part of this

    032 is fuel trims.. the learnt fueling adaption since last faultcode reset

    makes you wonder for all those who claim they already have 280bhp-300bhp+ on "some" rollers, will also be max'd on their duty cycles...

    Oh bum! I've been resetting the engine fault codes every couple of days due to the EVAP system error I get now i've removed the charcoal can so the 032 figures might not be very helpful at the moment :(

    I'll drive it about a bit and wont reset the code if the CEL comes on just so we get some decent readings.

    A custom map will fix all these issues you know... no more CEL from stuff you have removed and injectors/4bar dialled in correctly... plus tuned fully to take advantage of all the work you have done with the manifold/large port/wmi etc...

    Westicles, I've got a 4 bar fpr sat in the garage that you're welcome to try. Drop me a text with your address and I'll post it tomorrow or saturday :)

    It's definitely something to consider it's just a shame this has reared its head just as i'm about to move house and car money will be dramatically reduced :( hence why I'm trying to make do with what I currently have.

    If I can get this setup to fuel ok and not run major high EGTs I'll be happy for the time being as it does feel quick through the gears.

    Found this info on the TT forum from Awesome about running the 4 bar FPR with revo stage2:

    Well... he is correct to a degree... just fitting a 4bar doesn't enhance the performance as such but... in your case it will provide a degree of fuelling headroom and the higher pressure does atomise the fuel better so this can lead to better idle and a better overall air/fuel mix...

    Obviously at the expense of extra strain on the std pump but yours is a new one so will be fine for the foreseeable future

    Bit off subject and sorry for spamming, but I'm now getting an eml for my evap which has been coded out? It seems to have started to occur after unplugging the resistor briefly, and reseting fault codes through vcds as well as a tb reset? Any ideas?
    Cheers

    it is likely a different resistance value.. a connection issue.
    n80 must bee seen... incorrect flow is what would have been coded out, although I dont remember doing this? (could be me.. memory of a goldfish and all that)

    4 bar is definitely the thing to try next then. I can always get an inline pump at some point in the future if needs be.

    More info I've found:

    I did wonder if it was a connection issue as had pulled it out ( resistor has got little spade connectors soldered on there so could be inserted into oem plug ) to show tam and Westy a couple of weeks ago but have since checked it and all looks ok but now get eml for it?

    I've always got a the incorrect flow code but never got an eml from it and think may have jinxed it by telling / showing westy and tam the resistor and happily saying don't get any eml from it...doh :(

    Ps sorry for the hijack although slightly relates to one of your issues ;)

    I'm finding a lot of contradicting info on 4 bar FPRs with Revo Stage2! It seems like the TT boys say it's awaste of time but the Skoda lads are saying it's needed. I even found info on Revo Stage2 products saying it is needed for stage 2:

    Revo Technik ECU Tuning Stage 2 Software for 1.8T Audi and Volkswagen Vehicles, Revo, Chip Tuning, Revo Technik Products & Other Performance Aftermarket Auto Parts - North American Motorsports

    Yet Revo's own website doesn't mention it as being "required":

    Revo | Audi

    I suppose it's all down to how the car is running.

    Not sure why you are researching it mate tbh... facts are you have maxed your injectors... fitting a 4bar while running on your current map will give you a degree of headroom fuelling wise even if adaption will pull a bit out...

    If you want it right then its custom map time... you don't need to buy injectors as the 4bar will turn what you have into 440cc's effectively... the custom map will be scaled to suit and adaption won't be trying to pull all the fuel back out...

    I was only researching as I was wondering if Revo themselves recommend it or not, still not got a proper answer lol.

    Plan of action is this:

    Fit Prawn's 4 bar and see what the fuelling is doing in VCDS, if all is ok I will leave it as it is for the time being. I will then discuss with Bill availability and costs for a custom map at some point.

    I don't want Bill to spend a lot of time and me spend a lot of money on a custom map only for me to then need the same amount of time and money spent remapping it in the future for a BT.

    Pending what BT thinking of as for instance was going for gt28 and went for 550cc injectors on a custom map now then mapping won't be anywhere near as difficult when swapping to BT as been discussing a simular situ with bill at the mo about daves TT with future spec for upgrades as probably will go with a custom map with 550cc injectors with stage 2 spec hardware so costs are lower for hybrid ir other future spec?
    May be able to do something simular? ;)

    K03 cars needs it K04 cars dont - REVO

    end of

    thats the revo spiel

    Remeber... these are stage 2, generic remaps, and when revo did these, it was'nt on cars running higher flowing tips or manifolds.... so the goal posts have moved....... and this is where custom maps come into play

    If you plan on a BT at a later date... an option is custom map on larger injectors now, so when BT comes, if it comes, the injector scaling is already done, and you wont be paying full wack for another custom map..

    Ok, so what size injectors will be the intermediate between my K04 and a possible GT BT in the future?

    EDIT- Just saw Stacey say 550cc, is this the recommendation then?

    620-870 ranges depending on flow of turbo chosen..

    I've not thought that far ahead yet not to mention I have zero knowledge of BT setups! :)

    If I say 550cc injectors what would be the GT turbos I'd be limited to and what sort of power would I be looking at. I can relate to power ;)

    620cc region.... ok for high 300's

    Ok so ideally I'd want larger injectors because I'd want 400+bhp from a BT. What size injectors would you recommend for that and would it be possible to map those for a K04???

    620cc.... perhaps, and 4bar if you indeed did go for >400bhp
    should be mappable on k04 yes
