So i need to buy a good quality wideband controller for my turbo build that uses the NTK L1H1 O2 sensor and I need it to read OVER 20-1 accurately. I have been researching widebands for months but the only one that seems to meet my needs is the Motec unit and I dont really have an extra $1000 laying around.


I would like to find something under or around $3-500 if I can

thanks for the help

 

Contact PLX. I know some of their wideband displays are capable of at/or over 18:1 and still may accept the NTK sensor. Other than that you're looking at a MoTeC or similar

 

are you using this on a diesel? what are you running that has 20:1 AFR's?

also look into FAST EFI they may have their wideband

 

nope, still a gas engine

and under light load conditions around 25:1 is where the engine likes to run



And it looks like the FAST EFI widebands use Bosch sensors, and as far as i know NTK's are the only sensors that can read over 20:1 well. Also I dont think the PLX is capable, same Bosch sensor, damn, at least my tuner has a Motec.

 

I had a Daytona Twin Tech that used a ntk sensor and read up to 19.99:1.But like several other company's they discontinued it in favor of the less expensive bosch sensor.I think your right about not finding that range in an inexpensive wide band.

 

my lc-1 read to 20.0 but that doesnt help this.

 

The Innovate LC-1 can read some crazy lean AFRs, but to actually see them with anything other than a laptop you have to pair it with the XD-16 gauge as their other gauges have a more limited range.

 

I know the NGK AFX can use a NTK sensor, but as far as I know I think the AFX unit's range is 9.0-16.0. Can anyone confirm this as I am looking into the NGK AFX and the innovate LC1

 

you are correct the HIGHEST the NGK can read is 16:1

 

zeitronix reads to 21.0 but it uses the bosch sensor.

 

For what fuel???

And no i'm not going to turbo an Insight but this article shows a gasoline honda engine lean cruising @ almost 26:1. The writer uses a motec and also monitors the factory wideband which uses a NTK sensor, the readings from each are very similar.

NTKs can read higher then 20:1, they last effin forever (mines going on 190,000 miles OG sensor, and cost $200+


Just sucks I'm going to have to spend three times more than my turbo kit cost for a wideband, lol. Such is life

 

the probably on honda civic CX or VX. they are designed to run super lean. you WILL have issues doing that with a B-series

 

How cost effective is tuning for fuel economy going to be if you are using a $1000 wideband to do it? Maybe I'm missing something but that makes absolutely no economic sense.

 

Most Techedge widebands have the capability to read the NTK sensors. They have several models to choose from.

Edit: They only read to 19.0 afr though, sorry.

 

lol @ cost effective. People round here spend as much as there car is worth on a turbo kit. And even If I have to spend 1k on a wideband my total kit cost is way way less then average kit prices. I would still be ahead of the curve

I'm also thinking that since I already have the sensor that the Motec uses the unit may be a little cheaper to order without one.


So.....anyone here have a hookup with Motec, lol

 

thats cool, B series are overrated anyways

 

Motec= Tony1

 

what engine are you running so lean? especially on gasoline

 

so far i have ran aem, zeitronix, lc1 and now plx and i am the most pleased with the plx thus far.

 

Can you share? And explain?

 

zeitronix control box crapped out on me after about 6 months (awesome onboard datalogger, however.)
LC-1 grounding situation and finding the one it wanted was tedious and the constant need to recalibrate it was quite annoying. Sometimes it would connect to log works, sometimes it wouldnt.
AEM control unit crapped out on me after a few weeks
plx, so far so good and everything is pretty much plug and play and is self-calibrating.

 

I haven't had issues with AEM. I personally like it the best (used LC-1, LM-1, AEM). Only I've seen one issue on one car. That it doesn't read right unless it's warmed up quite a bit, I got a feeling that heater element is burned out in it (if it has one).

 

i recently played around with the innovate LM-1 and i saw some insane lean numbers come up like over 40 would flash up when goin from wot to closed in hi rpm. dont know how accurate it is at that lean but it looked pretty accurate around 20. dont remember what sensor it used though.

 

The engine is a SOHC 1.6

I was pushing for around 250 hp on a bone stock engine but I have a built single cam coming my way and hope to put down 400+ in the future on the same turbo setup with great transient response and power.

I have tons of pictures and specs but until I have some real numbers and AFR logs I think i'm gonna be laughed @ a bit. Hopefully tuning should be done in a few weeks.

I have a friend with a Lm-1 and its huge, lol, but seems to work well
