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...g-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..
