Cum zice Liviu.

si aveti wideband pe masina fetelor? ca asa sonda am si eu da fac pisu pe ea ca e narrow si da semnal am pulea.

V-a si spus tomi da tot n-ati bagat la cap.

tre sa caut eu pentru voi:
The FN2 has two semi wideband lambdasensors. They are essentially narrowband sensors, but have been fitted with pumpcells to enable them to measure within a wider lambdavalue, for instance lambdarange 0.5-1.2.
Don`t know the actual ranges, but it`s not as wide as a real widebandrange.
According to Doug MacMillan from Hondata, this is the reason the ecu can give less than correct closed- and open loop lambdavalues when mapped with flashpro. After repeated full throttle blasts on a dyno the engine gets overheated, lambdavalues from the sensors fall outside their measuring range and give skewed readings. Proper cooling down phases will prevent this. Their accuracy can sometimes be off by a full 1.0 AFR

hondata put in flashpro a compensation feature. This will compensate the error of the OEM sensor to make it a true wideband sensor.
So in flashpro there is the read AFR of the OEM sensor and the true AFR

The feature in flashpro have +- 0.1 maximum error.

hondata:

The Civic Si stock oxygen sensor is of a wideband type, however it does not read accurately once the mixture is richer than lambda 0.88 (13:1). Dyno testing shows that the stock oxygen sensor reads over 1 AF point different with rich mixtures.
However, our testing has showed that the difference between the stock oxygen sensor and the actual lambda is constant - there is no effect from exhaust gas temperature or time.
From there measurements we created a corrected AF sensor, using the correction as below. Mixtures leaner than lambda 0.95 (14:1 AF) were not corrected, even though the stock o2 reads richer than actual, in order not to alter the closed loop operation
The corrected lambda sensor is available for datalogging and graphing as 'AF.Corr'.
The corrected lambda reads very close to an aftermarket wideband

note= FN-2 sensor = civic SI

Stiu astea man, eu am facut comparatie intre masina lui Razvan (stock) si a mea (anumite modificari), si am vazut cam ce diferenta avem la AFR.

Sunt cam nou pe aici... Am avut o experienta interesanta... Am comandat ulei 5w40 pt civic 2003 , mi'a recomandat un prieten ... Nu eram hotarat de unde sa il iau si am gasit un site ... Eu nu prea ma pricep la cumparaturi online si l'am pus pe fiul meu. Initial am cautat motul dar un site care a facut un test de produse si a comparat motul cu castrol si liquid moly spune ca liquid moly cam prinde avantaj de ceva vreme... Am vazut ca nu mai au in stoc uleiuri... Si nu prea ma pricep sa descriu dar au ceva detalii si as dori sa stiu daca sunt reale, in 500km urmeaza sa pun uleiul, se merita acest liquid moly? L'am prins la reducere si din cauza asta l'am cumparat deja. Informatiile sunt pe acest site: http://agobooks.ro , la sectiune uleiuri exista liquid moly, este adevarat ce spun ei in acea descriere?

Multumesc!

eu sunt la al doilea schimb in crx cu liqui (nu liquid) moly. daca e vorba de synthoil, da, dupa parerea mea e un ulei foarte bun. liqui moly se fabrica doar in germania.

Și eu recomand Liqui Moly, o singură fabrică pentru toata lumea !
Eu nu am avut probleme niciodata cu produsele de la ei, indiferent de mașină !
Foarte mulțumit !

Atunci voi merge pe Liquid Moly, dupa 500km il pun , abia astept sa vad diferenta... Multumesc frumos!

am gasit un test interesant. in partea de jos e si o clasificare in f de perceptia testatorului

Buna,dragii mei ! Sunt nou pe-aici,desi am ,,fiara” asta de prin 2008 si am o intrebare:ati folosit careva sau ati auzit de uleiul Polytron ? Multumesc !
