Innovate Lc-1 And Power Fc

[Lived4eva]

Hey all,

Has anybody had experience with using an LC-1 wb O2 sensor with a power FC? I don't have a datalogit though this might happen in the future. I know that with the datalogit you can connect the LC-1 to the Power FC. But without it what is the best practice? I assume since you only have the 1 wb sensor you would plumb it into the front pipe after the 2 pipes merge. Leave the standard NB O2 sensors in place but unplug them and use the analogue outputs from the LC-1 to drive the O2 inputs? Sound about right?

Thanks

no you cant feed a wideband 02 sensor input into the PFC

you could use a wideband <-> narrowband converter for the 02 sensor signal but that would defeat the purpose

you either have the wideband 02 sensor runing to a wideband 02 gauge or to a digital input on the ECU

in order to drive it to the PFC correctly you need datalogit and plug it into one of the 5v digitla inputs

then you can plot and log digital 5v input from the wideband sensor onto the maps and lots for tuning

I was under the impression the LC-1 was able to output a narrow band output. The powerFC will not be able to use a wideband without the datalogit. I was planning on using this output to still drive the powerFC so it still has closed loop mode. While using the wideband to drive a AFR gauge and hooking up to a computer while tuning the powerFC. I guess what I was asking is wouldn't it be better to use the LC-1 as a wideband to narrowband converter rather than use the 2 standard O2 sensors that way you would only be really running 1 O2 sensor instead of 3.

LC-1 does have a narrow band output, you cold do exactly as you planned. At least the hand controller could tell you something meaningful by using the o2 volt to tell AFR, but a datalogit setup is far superior.

Another concern I had was going from 2 standard O2 sensors to 1. I know on V6 and V8s they run 2 but this would be because they have dual exhausts where as the GTR has 2 outlets that merge. Is there any advantage on the GTR to running 2 O2 sensors? From what I understand the standard O2 sensors cost about $150 each and should be replaced every 40k. For $300 wouldn't you be better off getting the LC-1 and gauge. It is a bit more work initially to get your front pipe modified but after that isn't this a more ecconomical and superior setup?

Please correct me if I am misguided I just can't figure out why anybody would bother replacing their standard O2 sensors if for a fraction more and a bit of work they can have a superior setup that will be cheaper and probably less problematic in the long run.

Thanks

yes sorry, i missed that you can run the narrow output from the wideband sensor/unit into the PFC (or any other stock style ECU) and let the ECU run its normal closed loop etc. the GTR PFC grabs the two 02 sensors and averages them, so you can parrellel it up no problems. it just has two sensors, as you said, likely because it has two exhaust outlets, so pick the average from both

Thanks for the feedback
