::I've been updating this post as I research further::
I guess what I meant was wiring one of the outputs to the ecu which is what I’ll most likely do now, won’t interfere with my tuner logging with Cobb atr software? He won’t want to mess with spreadsheet formulas and typically inputs the wideband via usb.
My LC-2 has two analog outputs “The default analog outputs are as follows: Analog output one (yellow) is 0V = 7.35 AFR and 5V = 22.39 AFR. Analog output two (brown) is 1.1V = 14 AFR and .1V = 15 AFR”
If the rear o2 is a low voltage input, is it possible to connect the brown to this and get accurate readings without a formula? I’m guessing not.
If I can connect the yellow to the ecu tgv, will this prohibit me from
Installing an aftermarket afr gauge down the line?
Maybe instead of getting aftermarket gauges I just get an android device, and eventually monitor boost, afr, oil temp, and oil pressure through btssm? This sounds like the best option over all. Maybe I can log this way too?
Looking at a refurbished nexus 7.... seems cheap enough and all it will do is this. Maybe connect to my phone and do maps.
Ok....
Getting excited about BtSsm.
"A recent Beta addition to BtSsm is the ability to reference some external sensors via a USB connection.
The list of supported sensors is still short: Innovate LC2 / MTX-L AFR sensors, and AEM UEGO AFR sensor.
The physical connection is like this: External sensor serial output -> RS232-to-USB converter -> OTG converter -> Android device"
So I could just plug the wideband direct into the tablet using usb.
My end goal would be to monitor AFR, boost, oil temp, oil pressure, post intercooler IAT, and fuel pressure via BtSsm. Looks like the AFR is easy enough. I'm running Speed density so I'm sure there's a formula to figure out boost from the map sensor. Oil pressure and Oil temp will require sending units as well as sensors im certain. getting those signals to BtSsm though might be tough. If I route the AFR direct to usb, oil pressure through the tgv and oil temp through rear o2 that might just do it unless that btsense module is released already. I may have to start a new thread, but I am super excited about these possibilities with Btssm. I've always been intimidated by the electrical aspects of it, but Im dumb enough to make mistakes and learn.
Damn it looks like I can do everything I want! The hard part is just figuring out how janky I want the wiring to be. And if I can use both TGV left and right as seperate inputs then I have even more I can do! I'm so excited. $40 dollars for a tablet is SOOO much cheaper then $150+ per vei dual gauge.
