wondering what would be the best AF meter for the money. I ahve a Ef hatch with a high compression ls/v

 

I am going to assume that you are looking for a wide band O2 sensor, controller and gauge setup. In that case, I would say PLX or Innovate Motorsports wold be the best bang for your buck.

 

I heard all good things about the Innovate MTX-L and how its the fastest rate..And its only 159 shipped if you look around on ebay..

i think streetrays or streetside or street something was the seller.. been a few weeks since i looked it up.

 

I have mtx-l im not sure if new models are direct usb or still serial port but one i have still needs a serial to usb converter

 

yea, still serial last time I checked

Only drawback is they use the Bosch 4.9 sensor which is better then the 4.2, but not as good as the NTK sensor.

Even the NGK Powerdex doesnt come with the NTK sensor in the box.. I find that quite odd.

 

http://www.wbo2.com/home/products.htm is about the only place I can find that uses a lsu 4.9 sensor. Pretty much all others listed are the old lsu 4.2

 

X2 other than the streetray part. I avoid that company like the plague. They have horrible customer service and never responded to any messages I sent them. They actually blocked me from any purchases due to giving them a bad review. I only learned this after accidentally trying to make a purchase without looking at the seller. There are other companies on eBay with the same low price. I plan on ordering my mtx-l in a few weeks after months of research!

 

Always a fan of NGK AFX, but the PLX does work great too.

 

thanks ive bought several things from streetrays with no issues

 

The innovate mtx-l works very well at a cheap price point.

 

x2. can't beat the price

 

If you actually hook up the MTX-L either serial or through the analog output it only updates at 12 times a second. Just thought I would throw that out there.

 

Can't go wrong with any of hte PLX wideband kits.

 

As opposed to USB?

Or you mean compared to the competition?

 

Oh and how does the mtx-l compare to the lc-1?

 

Had an LC-1 and I got some water in it and it took a crap on me so I just ordered the mix-l.

 

The MTX-L can't output faster than 12 times a second.

 

What do you use / recommend?

 

I personally use AEM.

 

The output is used for data logging, correct? How fast is needed?




How fast is the AEM?

 

OK so it sends it's samples 12 times/second, what's your point?

Is that not quick enough for tuning?.... So are you saying that the Bosch 4.2LSU sensor that they use in the EUGO is different from the one used in the innovate one?

 

It is not that it samples at 12 times a second(sensor). The output only gets updated at 12 times a second. Is it good enough for tuning maybe for some might not be for others.

The AEM is a live analog output. So whatever the sensor itself is sampling at the output gets updated at the same time.

So looking at a turbo K-Series Log as boost is ramping up starting at 4100 RPM 5.4psi in one second I get to 6500 with 18.5 psi.

 

Testing I have read shows the AEM behind the Innovate for accuracy and latency.

Accuracy;
Innovate +/- .10 AFR
AEM +/- 1.00 AFR

Latency
Innovate = <100ms
AEM = <400ms

However, speed isn't always the key in sampling, specially if it has a full point probability of error.... I'll take accuracy over speed!

Are you able to share the source for your information on the AEM unit?

 

Your accuracy is way off Innovate and AEM are both +/- .1 AFR

Latency what exactly are you talking about and about which products?

The Innovate MTX-L & LM2 is significanty slower than the older Innovate units. The fastest it will be from 83ms to 120ms. There is no more instant mode on the MTX-L

The current generation of AEM Widebands are around 100ms.

Where the two differs is that AEM uses an analog output so it is a continuous output of what the sensor is reading. The MTX-L has a digital output so it takes the number and outputs a stepped value meaning it will give you the same reading until it sends out the next number.

 

OK...I'm still working with my LC-1's, I think that is where we are bumping heads. I didn't realize the newer Innovate units were slower in processing and fully digital.

Little behind in the game I guess.
