Default LC-1 hook up to EMB w/ Autotune

Just want to make sure if the value I put for my programable LC-1 is correct to Simulate NB going to the AutoTune (brown wire).

1) I am going to use Analog #1 out to the AutoTune (brown wire).
What Value should I be programming to simulate NB: 0V = ?
1V = ?

2) I am going to use Analog #2 out to Monitor with an Autometer NB gauge.
What Value should I be programming to simulate NB: 0V = 18:1 ?
1V = 9:1 ?

3) Advance setting- Anything I need to change? Respond time?


4) Wiring in the unit.
RED 12V - ECU Pin power 1B
BLUE Heater Ground - Engine Block near to ECU ground.
WHITE System Ground - Engine Block near to ECU ground.
YELLOW Analog 1 - Simulate NB to Autotune Brown Wire
Brown Analog 2 - NB gauge monitoring
GREEN Analog Ground - ECU Pin Ground 2B
BLACK Caliberation - NA

If anyone find any information I just put up distrubing.. Speak out! Thanks!!

Look at page 14 of the LC-1 manual. That is basically the curve that a regular NB sensor provides. The manual says that this is the default setup for output 1.

I'd suggest a linear output where 0v = 20:1 and 1v = 10:1. This will make your NB display serve as a reasonably accurate linear indicator, with 14.7 (stoich) almost perfectly centered at the top of the display.

Looks good, though I don't think the ECU ground actually goes all the way to the block. Not sure where it grounds to, now that I think about it...

Is this the correct engine Ground for the LC-1 ??

1) for heater ground.
2) for system ground, on the same bolt with ECU ground.
3) I've ground the Analog ground to the 2B ECU pin.
