Only 12 left, I better order soon. Wonder if they sell them by the case. Take that Big Oil, I'm fightin' back.
Obviously. I remember these from years ago. Surprised they are still around. If you want to see a lot of snake oil check out some things in the audiophile world.Lol. Quackery
They are H02 not 02 sensors and my last post applies regarding H02 as they are input sensors to the ECU.Does anyone know if the CX5 uses narrow band or wide band O2 sensors?
It is a gimmick and in the long run could damage an engine.The Honda CRV mass airflow sensor swap does seem to get around 5 mpg more. I personally know a CRV owner who saw the MPG increase on 2 different CRVs.
I don't think it's a gimmick. Just not sure how the sensor swap works and why doesn't Honda use it to get better MPG from the factory?
What about what VW did with their diesel cars. Mercedes and a few others got caught tampering with those tests.Not sure where you saw that information about the test vehicles running different ECU maps for test. Most all Auto manufacture follow the CAFE under the USDOT for US and EURO market is very similar. So no "typically tune the car rich" for testing and posting required results. In the ECU world of engine richens not only effects all the drivability but will reais e the vary narrow of limits allowed in many country for exhaust emissions.
ECU calibration adjustments are becoming more for individuals and companies offering the service with some training and possibly certification to safely change maps in an ECU.
Going to larger Turbochargers over stock does not always mean the need to change sensors. This is always determined by the total boost targeted.
The MAZDA mapping in the ECU for a Skyactiv engine is VERY different than any other platform currently available for the general public. And Black smoke does not always ,mean high HC's and CO's which would be a emission related and EPA regulated exhaust.What about what VW d
Also, look at any turbo car that is GDI and factory tuned and you will see black soot all over the exhaust tips and bumpers. That soot is typically unburnt fuel.
Factory a/f for our cars are in the 10’s & 11’s. That very rich considering most tuners shoot for low 12’s A/F.
