Is it good to buy a wideband?
Or is it worth it?
I have a ecu(p06)(engine:d15b7) with uberdata on it
Wich one is the best I can buy to tune my car perfectly and have no fuel problem

Of course it is good and definitely worth it to me. I've got an LM-1 and I like it.

lm-1 is made by innovative ,I think
the lm-1 doesnt come with the data logging thing?

do you know If I buy aem uego,do I have to buy aem ems to plug it ?

You can datalog afr with the LM-1, but if you would like to datalog other inputs also you do have to buy the LM-2 or aux box. I think they make a good product. I'm happy with mine. http://www.innovatemotorsports.com/

i picked up a cheap one from radio shack for $18. the positive cable on the voltmeter goes to the green or white wire on the 02(i can't remember which one it was) then the negative you connect to a chassis ground. then you compare the voltage you get to this chart:

i did this and i was getting between 11.5/1 and 12.5/1 above 4000rpms. a wideband is better as far as not having to convert volts to afr but this is way cheaper and easier to hook up. hope this helps. :-*

hey trebor, so you just basically match up the volt on the graph to the voltmeter? can you explain more of your setup and more info on how it works? thanks, i am interested in your style of afr

I've heard some bad things about the aem like inaccuracy.
I'm pretty sure you do not need the ems and you can just use the wideband by itself.

You cannot simply use a voltometer to get an accurate AF. The working voltage range of a thingband o2 sensor is much smaller, and thus less accurate, than a wideband.

i can just say what i see. the dynosheet says i'm at 11.5/1 to 12.5/1 in the upper rpms 4k and up rpm and the voltmeter/afr scale says the same. have you ever tried it?

So what was the voltage at this "11.5-12.5" af?
