Good day sirs.  Was told via NGK support and also in the manual in not so many words that cutting down the mile long cabling on my AFX is a not recommended for calibration reasons.   I have a Miata and having that bundled up cabling under the limited dash space is dumb.  I don't think it would be an issue but I figured you fellas would have some insight and input.

I approve!

Hold me.

lol. It seems like such a minute change in resistance especially considering the sensor is calibrated and the unit can run on 11-28v.. It must be able to compensate for such a small change.



Should I worry?

 I think the problem in the cable may be in the shielding. If you splice all the wires and leave it open wiring it may get a mixed signal so as long as once you get done splicing it to tape it back together shouldn't hurt it.

The sensor is probably calibrated for a certain wire capacitance.  Changing wire length alters capacitance which effects the absolute value of your sensor offset slash calibration. Its not a big deal if you use your wideband as a delta measurememt and not think of it as an actual absolute number. (It probably wont 3v3n change the absolute number very much)

I'd never run an o2 to get absolute value, just to make sure the map is even and use the plugs to give the final word.

I can tell you I've lengthened the cable on my LC-1 w/o ill effects. I took an old PLX cable & put the correct end on it so the unit wasn't dangling in the engine bay.
