Why? The protocol is the same/similar between the two.JRSCCivic98 wrote:Supposedly there may one day be integration for LM1 into ecuExplorer, but it will not support the LC1... ever. At least this is what I gathered last time this came up on the Tari forum from Calvin.

Yes.
I don't think anyone is seeing my point here.. If you set aux output voltages to that of the stock rear o2 sensor and wire it in place of the stock sensor, you should be able to just log rear o2 in Tari and it'll be in the logs. I'm not sure what would happen if the voltage was outside of the expected range (I believe the lower limit is 2.8v for ~11.5AFR) -- would it scale or just read 11.5? You can scale the o2 voltages within the ROM, as well, which would fix that.

It's more complicated than you think. First EcuEdit can't log the front A/F sensor voltage, unless it has a secret ability to support OBD-II scan functions. Front A/F voltage isn't available via Subaru Select Monitor protocol. Second the voltages on the two wires between the ECU and sensor originate at the ECU, not the sensor. The Denso sensor's "signal" is the direction and magnitude of current flow.chuckdez wrote:qoncept wrote:Everyone is trying really hard to make this more complicated than it really is.
Yeah this isn't rocket science, it's just a matter of someone spending the time and providing a proven method on how to configure them to work.
We are just talking about simple voltage values. Matching the *output* of the LC-1 to the factory *input* allowable range.
ECM STI04 input Front O2:
Front oxygen (A/F) sensor signal (+) 2.8 — 3.2
Front oxygen (A/F) sensor signal (−) 2.4 — 2.7
ECM STI04 input Rear O2:
Rear oxygen sensor Signal 0 0 — 0.9
The front O2 voltage can be logged via ecuEdit.
Someone with a LC-1 could use the sensor stand alone while logging with ecuEdit front O2 V. Verify the 14.7 AFR(1 Lambda) on the LC-1 and record the front O2 V. Adjust the analog signal output on the LC-1 to match the stock voltage.
My next concern would be does the ECM CEL when it is unable to detect the heating of the front O2 sensor. When it's in a CEL condition does it still monitor voltage?
