i am interested as well...

yaya.. let us know so that I can ask my fren buy 1 from me at AU...hehehe

hey ppl, i notice something today on my afr gauge. after accelerating hard on high gear, then the needle will tick tick tick as i mentioned earlier la.. but after that when i decelerate, the needle point the leanest end..

then i got me thinking, is the ecu so smart that when it detects high vacuum with zero throttle position, the fuel injectors stop injecting fuel to the cylinder, causing super lean exhaust? got such thing ah?

 

[Choon]

no one can help? :p

narrow band vs wideband....wideband is the best and show exactly ur afr...narrow band like chirtsmax tree''......hehehhe..pening edi....

see some video on youtube..

of coz wide band is better la.. hehe..

btw, i would like to ask all the sifus here; i actually tap the signal directly from the signal wire (black) of the lambda sensor, near the extractor there? will it affect the signal being sent to the ecu and affect the afr also? i did those things as stated in my blog http://choondiy.blogspot.com/2008/06/pim-part-ii-gauges-housing-and-afr.html

last time I had a friend test my car with his AFR gadget, turns out mine's putting rich reading between 12-15 but stable around 11-12 during 3k RPM.
This should be notified as normal, right?
From what I read & heard, the optimum point should be 13 or 14.

it's known that 14.7 is the best ratio, but we never know coz each meter might show different reading as they have different voltage multipliers, something like tat.. mine totally sucks..

aiyo... how can suck...
if suck then you use vacuum meter de...
BTW I have Autometer narrowband AFR for sale... :P (terpromote pulak)
