Evening all looking for some advice on some data i retrieved from the car using vagcom. main symptoms i have are hard cold start, general power loss and car doesnt want to rev under acceleration past approx 5.8k rpms. several fault codes and a logged third gear pull below 3 Faults Found: 17526 - Oxygen (Lambda) Sensor Heating; B1 S2: Open Circuit P1118 - 35-00 - - 17522 - Shareware Version.

MAF looks dead. Did you try running it with the MAF unplugged? also second oxygen sensor might need replacing. B1S2 = bank 1 sensor 2

Car is adding alot of fuel from 2700-5800, any logs with actual boost vs desired? Would be nice to see the rest of the error codes... What temp readings are those in the last coloum? Check fuel pressure.

I retract my statement I was reading the injection readings as the g/s reading. MAF seems to be working

Something is amiss as the injector duty is mentally high... at 5720rpm the injectors are over 27ms and the ECU is adding 24% fuel.... that suggests a tired fuel pump Also notice the engine temp doesn't get over 80 degrees... 17522/P1114 - Ross-Tech Wiki 17522/P1114 - Oxygen (Lambda) Sensor; B1 S2: Internal Resistance too High 16706/P0322/000802 - Ross-Tech Wiki 16706/P0322/000802 - Engine Speed Sensor (G28): No Signal You have stated in the title this is a big turbo S3 so applying the normal methods of diagnostics is going to be tricky especially as we have no ide of the spec, what actual mods you have done, what mapping, stuff thats been removed, stuff that been uprated etc... going in blind atm.. I assume you have a decat? is the rear lambda plugged in? suggests the rear lambda is shot... (and seemingly not coded out?) <tuffty/>

Ok... found some info about your car... http://www.audi-sport.net/vb/a3-s3-forum-8l-chassis/174111-injectors-big-turbo-set-up.html I assume the above is still relevant and that you are using injectors that are too small? Seems your issues are too small an injector and potentially a tired fuel pump... please clarify current spec <tuffty/>

hi thanks for all your responses .. the car has the same spec as in the posted thread link, however i have fitted a new maf, cts, rear o2 sensor and spark plugs since then. in response to suggestions of a tired fuel pump i have got a bosch 044 inline ready to plumb in, i already tried a lower mileage used s3 intank one but no difference. for a while it was taking three cranks to start the car with a lot of spluttering, now its taking 5-10 cranks.. warm restart fine no problem.. wondering if that is fuel pressure related aswell

when jabba put those 450s in during the mapping session i did question it at the time but went with their decision as they are the 'experts'.. i did ring them up on a later date to discuss it again and they insisted that they were not too small so i focused on fuel delivery instead. from what i can understand from the log they do seem to be maxed out ? (my first log!) .. however when it was mapped it came in with 343bhp running lean at top end iirc, so the injectors must be good for that at least which is a lot more than its putting out at the mo ?

No... get um changed for at least 550's and with an 044 inline backing up the intank you can use a 4bar FPR to give more than enough fuelling overhead.. 440's on a wideband ECU is not good for this powerlevel... no overhead left... the logs say it all.. I have seen a few Jabba mapped cars and would rather not continue to comment but needless to say your current setup is not right... Bill maxed 550's out at around 360hp on a big turbo LCR recently... There are other tuning 'tricks' Jabba use too... I would guess you have a 'label' stuck on your MAF element?... My advice is this.... fit the inline, get 550cc Bosch injectors and a 4bar FPR then go to Bill or Niki and get it mapped properly... you will not regret it.. <tuffty/>

They are too small for that power As confirmed by the logs... simple evidence confirm fuel pressure and state your actual spec.... if you want help...

ok guys, changed over the 450 green giants for siemens 630s .. i know it needs mapping again but it pulls hard past the previous 5.5k cut-off point now which I am over the moon about ! My conclusion is that JABBASPORT are a joke, they fitted injectors that were categorically too small for the application and (potentially) compromised the entire engine build by letting me drive off with ridiculously high lean readings (mike told me it was the fuel pump at fault which i spent much time and money investigating to no avail). When quizzed on their decision they bull****ted my engine builder and even tried to keep my old injectors after removal (they were actually bigger than the 450s that Mike told me were 'perfect'.. 'not too big' Mike said) to seemingly hide their deviousness. In no uncertain terms I feel robbed by these people and would try to take them to the cleaners if I didn't have better things to be getting on with .. Anyway, moving on to those better things .. before I get it mapped again, is it worth putting on an r32 throttle body ? happy with any gains it may yield.. cheers

Yep.. just need to get a few minor things sorted out now (slight engine oil leak/slight exhaust leak/ext fuel pump fitted) and then will be looking to have it mapped, i guess i just need to give you a call (bill) when the car is ready to see when you have a slot .. ps is it worth fitting an r32 throttle body in conjunction with (already fitted) rmr manifold and agu head ?

what exhaust manifold and downpipe size? T25 manifold and internal gated turbo yea? what a/r hotside?

i have a t25 top mount cast manifold sourced from the ttshop (iirc) and a ceramic coated 3" downpipe .. was just about to order the dp new from the ttshop for around Â£6-700 when a lightly used one popped up on ebay literally the same day for Â£120 delivered .. touch !

heres my latest log with the larger injectors being the only difference from the log above [TABLE="width: 1024"] [TR] [TD="width: 64"][/TD] [TD="width: 64"]Group A:[/TD] [TD="width: 64"]'002[/TD] [TD="width: 64"][/TD] [TD="width: 64"][/TD] [TD="width: 64"][/TD] [TD="width: 64"]Group B:[/TD] [TD="width: 64"]'004[/TD] [TD="width: 64"][/TD] [TD="width: 64"][/TD] [TD="width: 64"][/TD] [TD="width: 64"]Group C:[/TD] [TD="width: 64"]'006[/TD] [TD="width: 64"][/TD] [TD="width: 64"][/TD] [TD="width: 64"][/TD] [/TR] [TR] [TD][/TD] [TD][/TD] [TD]RPM[/TD] [TD]Load[/TD] [TD]Inj.

too short a log and odd blocks to log imho I usually look at 002,020,115 and 003,115,118, if looking for fueling things 001,031,118 etc etc and 3rd or 4th gear pull 2krpm - 6krpm

ok, its only my 2nd log so still experimenting next time i'm out in the car i'll log those blocks you suggested.. when you say the duration is too short, how do you mean exactly ? use a longer gear or do repeated pulls ?

...this.... That looks like you used 1st or 2nd gear... 3rd or 4th will give more data over the rev range... 200-500 rpm steps rather 1500 rpm steps as in your last one <tuffty/>

Shame you cant change the sample rate for whatever gear you use so you dont have to go breaking speed limits

Its more the overall speed mate... logging multiple blocks slows data capture down quite a bit... you can go into the advanced blocks section and select individual params to log to get rid of the chuff... this speeds things up a bit but the faster logger I have ever seen id ME7Logger on NefMoto... its not for n00bs though.. <tuffty/>

ah ok, cheers tufty .. i thought that was a 3rd gear pull but may well be wrong, will do some more anyway .. like superkarl says i was concentrating on my speed mostly and if any rozzers were lurking around. It seems quite hard to find a place thats 'safe' to do some 'testing', empty A road/Motorway slip-roads seem the best option, not many round here are flat though

private roads - lol dyno's difficult otherwise to find stretch of road to explore revs in 3rd gear or above to 6krpm..

yes it is difficult .. plenty of private roads round my way, but also plenty of speed-humps so a definite no-go unless you like flying !
