During the process of building my Weber 32/36 equipped g10 my research convinced me that to properly tune the weber I should really have some means to accurately read my air/fuel ratio. This, of course, means installing a wideband O2 sensor with associated hardware to read the sensor.

After doing a bit of research into what was out there, I decided to go with the least expensive option I could find, which happened to be the Innovative MTX-L product. The MTX-L appealed to me because it included everything that was needed, and the display was an easy to mount standard 2" gauge. The price, while a little high at $158 purchased off ebay, was the lowest of any comparable product.

After receiving the product I was impressed by the quality and contents of the package. The gauge comes with 2 faceplates (black or white) and 2 bezels (black or silver), has an integrated data logger and connections to integrate the sensor into other data-logging systems, as well as connectors and associated cables to monitor and log the gauge output in real-time with a laptop using the provided software (LogWorks). The O2 sensor comes with an 8 foot sensor cable, which provided plenty of length to mount the gauge in my car (which, admittedly, is not a great feat considering the diminutive size of a Mk1). The quality of the cable appeared to be good, with no flaws in the connectors or cable itself. Also included in the package is a basic manual which covers installation and how to calibrate the unit, while the full manual is available on the software CD.

When the unit is first powered up, the display shows an indication that the sensor is heating up for about 30 seconds or so, then starts indicating the detected air/fuel ratio. The rate at which the display updates is near instantaneous, so there is virtually no lag in the readings. During the process of tuning my carb, I did notice that extremely rich conditions (where the car is starting to misfire) causes the gauge to show an over-lean reading, which I assume is due to the fact that the unburned fuel is not detected by the sensor. This is easy enough to deal with as long as one has a working nose, because the smell of unburned fuel in the exhaust is unmistakable ;).

All in all, I am very pleased with my purchase, and would recommend this gauge to anybody who has the desire to monitor their air/fuel ratio for whatever reason. I know that, in my case at least, the data provided by the gauge was invaluable during the process of properly jetting this carburetor for my application. Unfortunately, I have yet to try out the real-time monitoring software or the on-board data-logging capability, as I do not currently possess a working laptop, but if it is anything like the rest of the package, it is top-notch.

:thumbsup:

I have one of these Innovate widebands too and it's the bees knees. I've tested the datalogging capability and it works great.

Further, and perhaps most importantly for those of us still using the OEM ECU or piggybacks, it can simulate the original narrowband sensor's outputs so you can mount it in the existing bung--if you have some desire to do so (ecomodders?) you can even "fool" the car into running rich or lean in closed loop operation by tweaking the simulated output. I did a lot of research and nothing else does this.

Caveat: simulated narrowband only seems to work most of the time. That isn't a big deal if your tune is decent to begin with and, again, nothing else will do it, so I can't complain too much.

Mine has also thrown an odd error once :huh: but it was fine after I restarted the car and it's an amazingly useful tool.

OF course, like everything else I buy, prices drop AFTER I buy something...

A couple months ago when I was looking for a/f gauges the Innovative was about $20 cheaper on ebay...
