I had an AFX and loved it. The tune was also spot on.

I wonder if an NTK sensor would show an improvement in this department? I always used the bosch the NGK came with.

I had this same issue with my NGK-AFX. I ran both the power and ground directly from the batter in hopes of eliminating as much noise as I could. I used a switch to controll power to the w/b. Even...

Does he have headers?

I connected my signal ground to the MPVI EIO plug. I didn't remember reading that part of the manual.....maybe it was revised after I bought mine. Either way, it doesn't "appear" I am having any...

Thanks for the help guys. I have actually be running around this way for ~3 months. I mounted my switch right beside my ignition switch and its engrained in muscle memory to turn it on before...

Does anyone see a problem with this? I have my wideband powered directly off the battery with a switch in-line that I use to turn the wideband on and off. I figured this would reduce any voltage...

Interesting that an NGK rep is stating the only advantage of the NTK sensor over the Bosch unit is its ability to handle race fuel:doh:

I bought my AFX roughly 4 months ago and it came with the Bosch sensor.

I have been very pleased with my AFX thus far. Aside from constantly having to slightly alter my HPT equation to match the display, it has been consistent as hell. The unit is hardwired and I just...

Calibrated recently and allowed to warm up for ~ 60min or so. It seems like the voltage is always varying ever so slightly.

Does anyone else have to re-edit their formula to match up HPT to their display before every tuning session?

I have an NGK AFX powered and grounded directly from the battery, which makes...

I have mine powered and grounded directly from a battery and use a switch to turn the w/b on/off. I still have to modify the equation ever so slightly. What I have figured out is that matching the...

I am glad I am not the only one who names my logs by the frustration they cause me haha.

I ended up using MAF sensor cleaner

I don't know about you guys, but I have to modify my equation every single time I go to log my car to make it match from my HPT readout to the NGK display. I have a very accurate way of doing this...

Is there a particular type of cleaner you guys might recommend for cleaning the newer, card style MAF's? I would assume your typical electronics cleaners would be sufficient, but figured I might as...

Is E10 the fuel that says "may contain up to 10 percent ethanol"?? If so, I have been wondering about the quality of that fuel. Its seems some tanks my car runs like a raped ape with no knock, then...

With my Evo, I copied the high table to the low as well. My tune was set up safe enough that a bad tank of gas wasn't going to fubar me and I only ran 93oct anyways. Just depends on how safe you...

Welcome to the world of F/I ;). My Evo picked up 60whp and 70wtq w/ just a tune

Just wanted to update a bit. I loaded a open loop tune from WS6FirebirdTA00 and the a/f was WAYYYYYY more consistent. I was also able to hook up my w/b and verify this even though it is reading a...

My NGK also shows this max using the default NGK PID. I have not tried a custom one yet. I am however still showing a .06~.07 a/f difference from the guage display to the scanner.

Guys, I know it isn't a constant number....however, I have never seen a car vary up to 3 full a/f points at times just at idle. I w/b tuned my Evo, so while I have not messed with an LSX motor/tune,...
