Wide vs Narrow Band

[joelittel]

Can a sub par controller cause sensors to fail?

If so I’d advise anyone interested in purchasing a wide band oxygen sensor to look into other brands.

Let me put it to you this way. The Bosch LSU 4.9 is the most common wideband sensor in the world. Every car built after ~2005 has at least one. They almost never fail.

The innovate controller on the other hand is known to be a "bit wonky" (i.e. inaccurate). It seems likely that it's the reason your sensors are frying. Could also be the placement of your sensor, but I doubt that. I've seen engines that had one sensor per cylinder - which means 4 of these bad boys basically 4 inches away from the combustion chamber. I can't speak to the longevity of those setups, but I also didn't hear the owners say he has to swap them out all the time either.

I've known two cars that had issues with the innovate. Both have gone to AEM. I run a PLX controller.

Thanks for the advice. It is helpful to me and hopefully anyone else looking to install a wide band.

Innovative recommends p;acement a min of 18 inch from the exhaust valve to avoid overheat/burnout.

Placement of sensor in individual runners (even in 2 cylinder runners) causes a significant pulsing in the reading and therefore a question in the reading. 2 cylinder runner placement caused a bounce from 12/1 to 14/1 all the way from 1000 to 4000 RPM.

I made sure my sensors were installed over 18” from the valve but it didn’t save them from failing.
