^^ anyone?

 

I've had an LM-1 for almost a year now and am very happy with it.

PLX's new r500 looks interesting. http://plxdevices.com/R-500_productinfo.htm
It displays AFR, EGT and knock and is able to datalog.

 

I agree, I think I'm sold for the PLX R500, the display and features are very nice.

 

After doing a little more searching I found Klaus' patent application. The heater and pump cell control looks pretty clever. Where did you mount it, the stock location? If so, any problems with temperature being too high?

If your EGTs dont exceed 1200 degrees for extended periods you should be completely fine. If you use a heat sink made of copper or one of the HBX-1s the sensor can stand up in even higher temps. Up to 1700 degrees for limited (undefined) periods of time.

 

The sensor is mounted right in front of the cat. I have pics on the Innovate forums:

I'm poking my nose in here because I am trying to find the best fit for me as well. I have a feeling MINES13 either contacted Innovative, or he works for them, because I got the same responce from them as he posted in here. Here's what I got from PLX:

Thank you for your interest in our wideband controller kits. I will attempt to give you a brief comparison of our products vs. the Zt-2 and LM-1.

M-500 is basically a M-300 with wireless USB datalogger. There is no internal memory on the M-500.

R-500 vs Zt-2/LM-1

1. R-500 has a built in LCD graphical display vs. the text LCD on LM-1 and Zt-2
2. R-500's footprint is small vs. larger LM-1 footprint
3. R-500's is firmware reflashable (future firmware updates will improve the UI and add even more functionality)
4. R-500 has over 80 min of onboard memory for datalogging at 10 samples a second for 6 channels (2 speed, 4 analog) vs. no internal memory on Zt-2 and 44 min of memory on LM-1.
5. R-500 can be used to monitor knock both as a interpolated voltage and also audibly using headsets vs. no knock monitoring capabilities on LM-1 and Zt-2
6. R-500 has warning LED that can be fully configured with up to 2 arguments (can be used as shift light, or other warning light) vs. no such equivalent on
LM-1 and Zt-2.
7. R-500 has user programmable wideband output curve (as well as the 0-5V linear wideband output and 0-1V stock narrowband simulator output) vs. no such function on the Zt-2.

R-500/M-500 vs. Zt-2:

1. R-500/M-500 has built in display (controller and display integrated), Zt-2 has a separate display (controller+display).
2. M-500/R-500's software is more refined. (Feel free to download PLX Logger 2.0 from our webpage and play with it.


R-500/ M-500 vs. LM-1:

1. R-500/M-500 does not require user calibration. The R-500/M-500 is designed to auto calibrate and the controller is precalibrated during our manufuring.
The LM-1 requires frequent free air calibration (meaning that you need to remove the sensor from your sensor bung and calibrate it).
2. The R-500/M-500 does not require heat sink on wideband sensor nor does it have sensor timing "crashes". Many LM-1 users need to install heat sinks on their sensors to ensure that their widebands don't throw a error code when overheated. The R-500/M-500 is designed for full compatibility with the Bosch sensor and does not "crash" when running hot.
3. M-500 can be used with EGT up to the limit of the Bosch sensor. Bosch sensors will get damaged at temperatures over 850 C (1562 F). The instructions on the LM-1 tell the user that a heat sink needs to be installed at temperatures over 500 C (900F). The M-500/R-500 does not need such a heat sink and will work properly at temperatures higher than 500 C (don't exceed 850 C or else the sensor gets damaged!).

We wish the very best as you research for the best datalogging wideband solution for your vehicle. Feel free to contact us if you have any additional questions.

Here's what I got from Zeitronix:

Thank you for your interst in our products.

Zt-2 offers the highest sampling rate in the industry, 74 samples per second per graph! You will not miss a bit! You will see how smooth are the logging graphs due to the high sampling rate. Internally the Zt-2 samples the sensors over 1000 per second. Also, according to the independent tests Zt-2 is more accurate than LM-1. We cannot confirm this since we do not own the LM-1. Zt-2 is a fraction of LM-1 size plus it comes out of the box with more features making in more cost effective tuning solution. Zt-2 was called the best bung for your buck when the Import Tuner tested all widebands available on the market.

Thanks,
Zeitronix

 

The LM-1 has a text and bar graph display not just a text display.

True.

As does the LM-1.

The LM-1 samples at 12 times per second and the 5 inputs on the AuxBox are completely user defineable.


There is no accurate method to detect knock using a standard knock sensor on a modified engine.

As does the XD-1 display for the LM-1, plus it can display any logged channel.

The LM-1 and LC-1 do it aswell.

First of all, it is not frequent but if the sensor does fall out of calibration spec, (which happens after a few hours of "rich condition" constant usage) The LM-1 can bring the calibration back into factory spec. The R-500/M-500 devices rely on the factory calibration resistor that is only accurate when the sensor is new.

The LM-1 works over the entire EGT range of the sensor, but Bosch (the sensor all three companies use) also specs a maximum bung tempeture of 500 degrees C; which when exceeded causes inaccurate AFR readings or sensor dammage. The PLX and ZT2 devices do not monitor that condition, which can be easily exceeded in an modified application. The LM-1 does and will throw an error to warn the user that the sensor is operating outside its designed spec as opposed to just providing you inaccurate AFR data which would be pretty dangerous if you are actually tuning the vehicle.

A for effort.
