That's how mine works.

 

get the digital it looks better plus you get an accurate reading down to the tenth of a point on the afr, where the analog its kinda guess work. Im happy with mine, 35k on it no real issues with it. Go digital save the analog for your boost gauge.

 

35k on original sensor too? Glad to hear these last I don't have more than 2k on mine. Hoping it lasts that long.

 

Great! That's what I have in mind too. I thought I was having a bad batch.

 

ulpps...doesn't sound good.

 

I have the same question.

 

Gotta think that the tailpipe sniffer is going to get just a tad bit of outside air due to it's location at the end of the exhaust. It won't be much outside air but it is enough to throw off the true afr's.

 

Just wondering, the tailpipe position does affect the afr on idle but not sure when there's a constant flow of exhaust gas at high rpm. I would have thought there's at least a delay in readings but the actual afrs remain the same regardless of the positions of the sensor? Hope it makes sense lol.

 

Has anyone made afr comparisons between aem and dynos? Do the values differ a lot?

 

Also, at what rpm do you start seeing 11 afr? As soon as you wot?
Still learning my new toy!

I must say this site has been really helpful!

 

I have the aem analog and it read from 8.5-18. Its nice & I love the way the dial sweeps but get a different one so yo can run with evoscan if you do that or have any interest in doing that

 

Digital is very nice, and you can log with it. Its nice not to have to eyeball the AFR's during pulls lol

 

I've had my Zeit. unit for a very long time.... since 2005 probably, the original unit and sensor... for well over 55k miles.... and its been mounted at 3 o'clock the entire time... its been so long I can't really give you an exact time frame or mileage lol

Lets just say I like it so much I bought another for my evo..... original is on my GTi

 

to be honest the tailpipe sniffers only work to monitor afrs as long as you dont have an exhaust leak at any flanges, or manifold to turbo/head. Any small leak can still throw your afr off a few points. My aem wideband is mounted on downpipe before cat flange. I like it, only thing I wish is I wouldnt have went cheap n bought an autometer boost gauge is like 1 or 2 psi off on reading, but an analog and digital gauge, looks ok but ive got mine on the steering column pod. Too many distractions, but I didnt want the jet fighter cockpit look on the A pillar haha

 

+1
a properly mounted wideband and tailpipe sniffers are only accurate if you have NO exhaust leaks. why do you think tuners want to check for exhaust leaks before starting the tuning process.
