good day, i've tried hooking up my lc1 to my s300 and there seem to be a problem with the af in my db gauge. btw, this is how i hooked up mine, brown (analog 2) this is your wideband signal, connect to D10 (ELD) on your ecu , yellow (analog 1) this is your narrowband signal, connect to D14 (O2 signal) . when i tried running the car the afr seems to be a bit high but when i tried removing the brown wire which is connected to D10 the afr goes back to minus 1 compared with the connected brown wire. what seems to be the problem?thanks.

 

Did you remove the resistors at r138 and r136 ?

 

is this because the OP is in a different country where the ECUs are not the same? im curious cause i bought a s300v2 installed to a computer you guys provided (thanks!) and am wondering if i would need to do the same?. I also purchased the LC1.

 

If you want to use the D10 (ELD) circuit it will work better for a wideband sensor signal if you replace the two stock resistors.

 

If you want to use ELD as your 0-5 volt logging input for a wideband you should cut/remove the resistors at r136 and r138 on a usdm ecu.

I wasn't able to cut the resistors at r138 and r136. Will try to cut it. I am correct with the wiring ? lc1 brown wire to d10 and lc1 yellow wire to d14?thanks. and also do i need to ground the lc1 to the ground of s300?thanks guys. I've read in some forums that they wire the brown to d14. and tried to adjust the difference through the voltage and af tables and voltage percentage.thanks
