Hi all, a very big hurdle as far as the use of the very much preferred NTK sensor is simply the availability of the information as far as the software and the code to write the software to the NTK control chip. This information is simply not available to who ever asks for it making it virtually impossible to write to the hardware chip that the NTK sensor is controlled with. I have used lots of different brands of wideband meters for many many years and have had my share of sensor failures, mine are more so just plain worn out, use of leaded fuels such as avgas, Excessively rich mixtures on a hot sensor that destroys them as they get cold shock when very hot. Dropping them, melted wires, and the biggest one the unknown, loan it out , used to work, get it back doesn't work anymore. Letting the battery run flat with the sensor hooked up. Lots of things will destroy these sensors and or shorten there life span, incorrect angle in exhaust allowing H2O to come into contact with the heated element causing failure. As we all know H2O is a by product of the combustion process and can not be eliminated. So unless you have millions of dollars to get the chips coded and a full reconfiguration of the main ECU or another CAN MODULE i doubt we will see much happen here. The best advice i can offer is to avoid the above mentioned sensor killers. Calibrate your meter regulary, avoid over rich mixtures. Poor tuning of engines that cruise at 11:1 instead of stoich or a little leaner if possible will save the sensor life also. Also in this day and age, is that really a genuine, LSU 4.2 or LSU 4.9 sensor. The other issue is if the sensor is connected to a controller then an analogue output voltage from the module to the ECU is not of high standard, the sensor may be fine and the meter is the culprit. And this is where we come full circle back to the Innovate LM-1 with no analogue volt output earth/sensor ground. Earth looping. This issue was big enough for Innovate many many years ago to design and build a GIA, GROUND ISOLATION AMPLIFIER to stop ground loop feed back effecting readings. There are wideband meters on the market running NTK sensors, with the intellect (i definatly don't have it) and the ability to buy the chips,maybe the code could be reverse engineered to get the base code to program the chip, who knows. Anyway just my long 2 cents worth. Regards Dave. P.S BY THE WAY DAMIEN KING THIS IS YOURS HA HA HA HA, SHOULD BE THERE SOON.
