    Thanks for the offer mate. I have the engine bed in now so I'm not overly fussed on racking up miles. I need to see what the furling is doing with the 4 bar FPR on. It might be a bi iffy so I don want to be to far from home just in case.

    Just read the fuel adaption figures before I fit the 4bar FPR clear the codes then go for some logging.

    Is that guide seriously suggesting fitting bigger injectors and running e85 by just tweaking unisettings?! That's surely just asking for trouble.. I can't believe anyone recommends that's an acceptable way of doing things... Am I wrong? Is unisettings that good and reliable?

    Some logs with the 4 bar FPR:

    [​IMG]

    Injector Cycle no higher then 96% now which is an improvement:

    Just need the experts to tell me what the fuelling is doing?:

    as suspected, the long term trim is pulling the added fueling of the 4bar FPR, but seeing as at WOT it relies on the maps rather than measured values, it appears to made a difference the the IDC's

    So what are you saying lol. I'm guessing it makes sense to keep th 4 bar frp for the moment?

    Did a couple of AFR graphs for comparison between the 3 bar FPR and the 4 bar one:


    3BAR
    [​IMG]

    4BAR
    [​IMG]

    As you can see, the 4 bar is making the car run slightly richer on boost but at least the injectors aren't being maxed out. I'm happy with the fuelling going on all the above figures and I did go for a bit of a blast this morning and the car feels strong.

    It's not running mega rich, only slightly rich. I'd rather it was slightly rich then having maxed out injectors. I only plan on using the 4 bar fpr short term until I get a custom map.

    What I don't understand is why requested changes from 3-4 bar? The requested value is taken from lamfa it's a value table thus it should request the same regardless, it's not like it knows you changed fpr. Only reason it might be different is if load is different but then the graphs aren't comparable!

    The graphs are made from "Lambda Bank1 specified and actual" block 031 so maybe it's slightly different to the map actually requesting the fuel :think:

    All logs were done on the same stretch of road in 3rd gear so load and conditions will all be similar.

    Not sure yet as haven't driven it with the resistor yet.

    It'll be nice to to have the ticking from the old solenoid, that thing is annoying!

    Fuelling doesn't always come from LAMFA... LAMFA is used under normal conditions but BTS maps and knock maps come into play should circumstances arise... any of these could be potentially throwing the logged AFR out depending on whats happening in the engine... the ECU calculates lambda request based on these conditions and applies the lowest requested AFR...

    Not overly conclusive tbh... would be better to assess this from the actual logs with relevant blocks to see what else was happening at the time... egt's, lambda live adjustment etc...

    Blocks 001 (lambda control), 031 (Lamda request/actual), 112 (EGT)

    Block 002 will give you injector on time...

    There is also an enrichment factor for the calculated EGT's which (from what I understand) is measured from the heater temp of the Lambda probe... this is typically set to 820 deg on the S3 and is where the ECU starts to use enrichment tables beyond LAMFA... this (I think) is on block 034...

    This may be of use too

    I've not had a chance to go out and do any more logging yet but I have noticed my MPG is better! It's actually climbing! I think this is possibly a misreading from using the 4 bar FPR.

    Noticed today that my exhaust is slightly blowing by the de-cat where I had taken it apart. I've got to the stage now where I think it's time to get a custom cat back system.

    I've only had one quote so far and that was from MIJ near Brum for £395 for a 3" system. What seems to be the going rate for a custom 3" system and can anyone recommend anywhere in the south east?

    MIJ used to be good but seems they've slipped. Could be a test mule for piper? Just means you'll have to take a trip to Folkestone but the system is free I think or atleast very cheap. Bit far up this way although not too far once you move. BTB in daventry. Bit more money perhaps but a damn good quality system. Just look at their site lol

    Tell me more about piper? I don't mind bein a test mule for a cheap system :eyebrows:

    Edit: just been on their site. Why would it be cheap or free?

    Because it'd be a development system they haven't done before. They don't do anything Audi currently according to their site. Unit18 developed a few systems with piper recently, that's how I know. The 8l s3 scene is pretty big, just look at the amount of people you see posting up with new cars. Worth an email perhaps. Looking around earlier all the systems I found were over 500quid so if they could do better than that they'd be onto a winner.

    So you don't know for definite that they will do a cheap system lol. I've got a couple of local places to get quotes from first but I might bang an email to piper just to see.

    I pinged over a nice email to Piper to see what they think. I doubt they'll do anything for free but it's worth a go to try and get a cheap system as a guinea pig car. I'll let you all know what they say.

    i think I need a 3'' zorst as well these days.

    It's all well and good having an ultra quiet car, but I fancy a bit more sound if I'm honest! It only records 86dB on the sound checks at trackdays!

    Just need a smaller backbox or cut it open and pull some of the baffle out. My jetex is too quiet for my liking. The backbox is huge and it's the only box in the system. Expect mines about the same volume as prawns just about. Sounds nice around the mid range but up top is mainly engine sound and down low there's hardly anything. I'm used to asbo spec systems lol.
