We have spoken to Mr. Mike Kojima the author of the Fordmuscle shootout and got first hand test details. According to Mr. Kojima his article was edited prior to the publication.
The tests were done using Innovate methodology and Innovate equipment.
There were several major flaws in the test, including but not limited to the way the O2 sensor was exposed to the test gases.
One of the major test flaws was reading the AFR value from the Zeitronix Zt-2 analog output using the Innovate logger. There is a voltage drop on the power-ground wire caring 12W of O2 sensor heater power and offsetting the AFR value. Reading the AFR value from the Innovate digital output but logging a raw Zt-2 voltage using Innovate logger subjected the Zt-2 AFR reading to the voltage drop, noise and Innovate logger analog to digital conversion offsets and conversion time.
The Zeitronix ZDL datalogging software should have been used to read the digital AFR value from the digital output of the Zt-2; not any other product brand.
Using the Innovate analog logger to read the Zt-2 (and other wideband meters) analong AFR value gave Innovate LC-1 unit, a half track length advantage in this 1/4 mile race. We either start from the same line or this test is not valid at all. This is an absolute violation and unscrupulous action.
The same goes for the "latency" measurement. The Zt-2 AFR readings were obtained by using the Innovate logger and software.
The Zeitronix ZDL software was not used in the test but scored the lowest.
For those who use our ZDL software know that hitting Enter starts logging, Enter stops. What's easier? "Clap on, clap off"?
Let me point out again that the other unit, which does not come with any logging software scored higher in the "Software" category.
Moreover, the Zt-2 scored the lowest in "ease of use" category. In order to get the AFR value from the Zt-2 all it takes is two wires to be connected to +12V and ground plus the O2 sensor placed in the exhaust stream. The Zeitronix LCD display plugs and powers up directly from the Zt-2.
