We should not need the heater because our temps are consistently high, also the heater in the auto is always being switched on & off to regulate the temp at low eng. RPM , this is only on OBD2 sys. ( newer cars, boats ) Heaters on the older cars was used to get the sys. to op. temp as fast as poss. for the Government,,,, no wait I mean emissions ya that's the ticket. David

You don’t need the heater in our application. Why hook it up?

Richard, regarding the Ellison TB
I have a friend who tried an Ellison on his rotary - never could get the low end and high end to work together. It appeared that (at least for the size Ellison he was using) that the range of airflow quantity below idle and WOT was outside the range of the size Ellison he was using. If he got the idle set right, he ran out of fuel on the top end. If he got the top end running right, the idle was too rich.
His engine eventually quit in flight, airframe was destroyed - he fortunately escaped injury. Just thought I would pass it on for what its worth.
Most O2 heater voltages are 12 -13 Volts - but, not certain about the Renesis O2.
Sensor output for narrow band is generally from 0 -1 volt, Wide band from 0 -5 volts.

I am planing to use an O2 sensor from a 2009 Renesis on my test engine. Does anyone know what the heater supply is? I am measureing 2.4Ohm, cold. Probably 5V? The connection is coming out of the ECU.
Would appreciate any info on that.
Still having issues with the mixture setting on the Rotec TBI (Ellison). No real flying yet, just a lot of crow-hopping down the runway.

Forgot to say, under diog. for RX8 they call both sensors HO2 not AF. ??? David.

Steve, another update on O2 sensor data,,, for a 2007 RX8 frnt. HO2 sensor is read in mil. Amps,,, 1.0 mil. amp is center point under accell is looking for decrease, under deccell looking for increase, did not give min.-max. for the high & low that I think could have been useful. David.

David,
Do you remember ballpark values for the amps and volts?
Thanks,
Steve

Steve, I'm not sure why but when diog. the other day on 07 Mazda 3 for a code P2188, Snap-on scanner shows me amps for pre cat. AF sensor & volts for post cat. O2 sensor & that is how they describe them in Mitchel Automotive diog. text. Hope this helps in some way. David R. Cook RV6A Rotary.
