Sziasztok Kis segÃtségre lenne szükségem. Hiba : kis alapjárat ingadozás 100rpm egyenletlen járás.. Lambda 1.00 ha dúsÃtom kb 0,85re egyenletes alapjárat minden tökéletes. Teljesen általános jelenség 1.5msec injector pulsewidth alatt: * With low injector pulsewidth, especially ~1.6msec and under that, even with the ECU configured for perfectly consistent injector pulsewidth, the fuel injected by injectors vary a bit: between injectors, and also from cycle to cycle => hard to tune... With most injectors of that size, often impossible to get perfect idle at 1.0 lambda (factory engines idle with 1.9 msec injector pulsewidth or above - obviously with smaller injectors). ** in the old days people swapped injectors between cylinders, but with the individual injector trim, that's hardly necessary any longer (except maybe in extreme cases with very big difference, mostly for diagnostic reasons) * Start with lambdatarget=0.87, but tune VE for 0.84 so that EGO takes away some fuel (the good way is to tune slightly rich, so that EGO only takes away some fuel when all is good). ** check the injector order and play a bit with injector timing (the sweet spot makes idle a bit better at somewhat higher lambda) ** See injector trim / individual injector pulsewidths: add +100usec injector pulsewidth for each (additive term!), and see how much you can take away before stumbling (take notes for each) *** After you find how much "margin" each injector has, you can set them reasonably (add less for injectors that allow less; add more to those that require more). If you're lucky, you can slowly increase lambdatarget up to 0.9 (or maybe even 0.95). *** Some installers who need very high power, but want to pass emissions: use staging, or a smaller set of injectors for the time of emission tests. *** But of course check "Validate" in VT, and the usual things... Ãœzemanyag problémára gondolok .injektorok tesztelve egyenletes porlasztás, mennyiség megegyező mind az 5 hengerre . Van e valami tippetek mi okozhatja a problémát? Köszönöm ---- New project: TODO: move it to different page. Mixing different engines on same page is explicitely not supported, because very confusing => causes misunderstanding and costs extra time for developers Volvo 2,5 RNC DUAL VVT * http://www.vems.hu/files/MembersPage/VolvoS/Volvo25RNC/v3.3_u003132-2014.08.01-14.32.44.vemslog * http://www.vems.hu/files/MembersPage/VolvoS/Volvo25RNC/v3.3_u003132-A-2014.08.01-15.55.05.vemscfg * Engine started (with your help, related to primary trigger VR polarity) * sg is weird though: engine is sluggish ** note: This type of issue is often hard or impossible to see in logs and must be traced on site. ** verify firing order (especially ignition) ** verify exact TDC. Don't blindly believe any mark on the wheel. Remove a sparkplug and VERIFY the mark, really. ---- Reviewed vemscfg/vemslog clt ign adjust table was not reasonably filled, adjusted config available here: To allow further timing and trigger verification please provide a triggerlog of engine cranking 8-10 seconds without IGN and INJ fuse - DB ---- Received vemslog by email, supposedly after uploading [adjusted settings] linked above. * received log: http://www.vems.hu/files/MembersPage/VolvoS/Volvo25RNC/v3.3_u003132-2014.08.06-11.28.53.vemslog Review: * Adjusted settings was not uploaded. Are you sure you are using an up to date VemsTune version ? To proceed in the right direction, issue: ** In VemsTune when having active internet connection, use "preferences -> update ini files from web" ** after that re-upload [adjusted settings] linked above * after that verify in VemsTune that "Tuning -> CLT/MAP Ign adjust table" is filled with all zero. * after that take another vemslog and report. Sziasztok! Először is köszönöm az eddigi segÃtséget. Most ismét segÃtségre van szükségem. Nem indul be az autó. Feltöltöttem egy trigger logot. Megköszönném ha ránéznétek. Ãœdv, Kitti :http://data.hu/get/8188022/v3.3_u003132-2014-11-03-13.12.17.triggerlog Dave says: triggerlog seems good to me, no trigger errors perfect sync. * good vr polarity on primary trigger, perhaps a bit high cranking advance 3-4 teeth BTDC = 18-24 degree * I would advise her to check engine timing with timing light It's only a triggerlog, a vemslog would be needed to check the rest. Will review when uploaded. Eg. TPS and injector pulsewidth should be checked first. (they said RPM was good). Solution was easy: Injectors were disabled. (safe-mode ?) ---- Please review my config: http://data.hu/get/8212368/v3.3_u003132-A-2014.11.11-13.39.52.vemscfg http://data.hu/get/8212369/v3.3_u003132-2014.11.11-19.09.49.vemslog Review report: * stay away of boosting the engine (or anything over part throttle) without having the basics setup * knock control is enabled with bogus settings causing over enriching, please load configlet "Disabled" to disable it until properly setup as advised (following procedure) on: http://vems.hu/vt/help/v3/v3_knock_control.html * config validate has one error, lowmap fuelcut to high (set to 26kpa) better 18-20 kpa * table kpa table unit = 4 selected not recommended for your setup (with 300kpa map sensor) 2 should suffice as recommended on: http://vems.hu/vt/help/v3/v3_ecu_calibration.html * ign table does not make sense, seems inverted logic (too much advance @ low rpm, not enough @ high rpm, nonsense kpa scaling) * because lotsof settings (even basic settings) are incorrect, it is highly recommended to take lessons from experienced tuners. Risk of breaking this engine is very significant! Best regards, Dave - DB |
