Why? Because I got sick of this crap:


That pile of **** autometer a/f gauge is worthless. Little LEDS are stupid.

Here is the apexi unit.


OMG! WTF? Is that a NUMBER??!??! For my air fuel ratio?? YAY!!!!

This thing was only $78 bucks too. It also has a voltmeter, o2 volt reading, and naturally the timer.

Turbo Timers =

 

nice.. so that a/f gauge from autometer is really useless then huh?? i was almost bout to get one .. but i heard that they are mostly for just looks cuz of the leds always going up n down.. (( cant get a good read on them ))

 

Totally worthless.

 

Hey Brian, what is that under the turbo timer and to the right of the clock?

 

Bottle Heater switch.

 

You went turbo?

 

haha i think he is still gettin ready for it.

 

He's more ready for it than I.

 

nice nice, how was the install?

 

wow i didnt know that the apexi turbo timer had all those other options with it.

 

cake

 

Does it read off your o2 sensor like the autometer a/f guage?

 

reads from the ecu.

 

apexi says it does but it gives accurate readings when everything is warm..

 

Yeah, it takes a few minutes upon startup to get a reading.

 

where did u get that price? the lowest i found was 98+shipping

 

Its just as accurate as the autometer guage then. Its only accurate on full throttle. No/Part Throttle it won't give you an accurate reading, unless you have a wideband sensor. It is less annoying than the autometer guage though since it doesn't have a light that moves around all the time, but that is what your car is really doing at idle and partial throttle, it is going from full rich to full lean trying to get to stoich. My friend has an autometer guage in his Maxima and its ecu works differently so it doesn't bounce around it stays in the middle or stoich unless he is at full throttle.

Not my observation. During cruise the apexi is not hunting. It might go from 14.5-14.7 but doesnt do any autometer crazy red green red greed crap. The apexi unit is quite nice and at full throttle it indicates a 14.6 a/f naturally aspirated and a 14.4 under n20.

 

...........

 

I believe that is because the autometer guage reads real time, and the apexi unit is 'smarter' and averages out the signal it gets.

 

It has to be. The 14 pages that were stuffed inside the apexi box has a chart explaining how it does this. I want to hook the autometer up to a snowblower or a lawnmower, and put a worthwhile gauge in its place. (EGT, oil pressure, water temp, etc)
