Power Enrichment questions

[joecar]

Try setting the NBO sim voltages to:
0V = AFR 15.1
1V = AFR 14.3

The other programmed voltage/AFR points correspond to CALC.AFR_LC11/2:
0.883V = 10 AFR
4.216V = 20 AFR

If you still have problems, try this:
keep LC-1 green and white isolated from chassis/engine ground...
i.e. have it go directly to the NBO signal low pin and FlashScan pin D.

Green and white don't have to go to chassis/engine ground...
Green is called "analog ground", but a better name would be "analog return"...
White is internally connected to green.

Just wanted to give an update on this.
I guess the title to this thread really should have been "Innovate LC-1 installation simulating NBO2", after seeing how it progressed. After changing a few wires around and re-programming the lc-1 per Joecar's recommendation I think things are working correctly. Open loop seems to be working fine (although the voltage seems odd to me), and Closed loop now seems to run great. I've been able to dial in the VE real well with the WB. I'm not sure that it's 100% correct, but the car seems to run well with this current configuration.

Joecar, I would like to know how you knew to program the lc-1 for NB simulation. I still can't find this anywhere (but it worked!).

Here's is everything I did to make this setup work:

I should point out up front that I'm using a custom pigtail on the NBO2 sensor. It basically plugs into the existing wiring harness and to the existing NBO2. Two wires still go to the NBO2, the other two are hooked with the LC-1 analog wires described below.

LC-1 red wire connected to switched power coming from Alernator (5A fuse)

LC-1 blue wire going to chassis/engine ground

Heated O2 low (pigtail from S10Wildside), LC-1 green and white wires all connected directly to pin "D" (middle external port) of EFILive interface cable.

LC-1 brown wire connected to Heated O2 high (pigtail from S10Wildside), which serves as simulated NBO2 return to PCM.

LC-1 Programming:

Analog 1 (yellow wire) -
.883V = 10.1 AFR
4.216V = 20:1 AFR
serves as WBO2 output to EFILive external interface (pin "C").
Uses PID EXT.AD2 in EFILive.

Analog 2 (brown wire) -
1.0V = 14.3 AFR
0V = 15.1 AFR
serves as NBO2 simulator back to PCM via pigtail from S10Wildside.

The results of this was:
in Open Loop HO2S11 PID showed 1.016V (this one confused me; I expected the PCM to see .445V)
in Closed Loop HO2S11 PID showed less than 1V (mimicing NBO2)
With ignition on;engine off HO2S11 showed .009V

The LC-1 default settings for Analog 2 are pretty much 1V=14.3, 0V=15.1...
The LC-1 user manual pdf also shows the same/similar thing.
When you think about it after reading descriptions of the stock NBO2 you will see that makes sense
(voltage swings up/down between 0mV and 1000mV very rapidly thru the point 445mV=14.7).

HO2S11 will show 445mV only for AFR 14.7, so 1016mV shows "rich" (but you can't really say what the AFR is, unlike a wideband).

How is your existing NBO2 connected (signal high and signal low disconnected...? power and ground connected...?)...?

Your exactly right, attached is a VERY rough sketch of what the pigtail looks like that I'm using. I kept the NB connected to the PCM to prevent any diagnostic codes. The NB is just zip tied to the Oil filter hanging out in the wind.

And Open Loop is running rich ... expaining the 1.016V reading. I just didn't think it would be that high of a reading. I've been leaning it out a bit, it was around 12.5 in most cases. This car would not run well at all in OL at 14.7.

Could be the NBO2 degraded over time.

What 'Response Speed' should the LC1 be programmed to?

[joecar]

Trying to remember what I set mine to, I think 1/3 or 1/6.

does this same set-up apply to the 5 wire lc-1 as well?

There's a 6-wire and 7-wire... they are the same except the 6-wire has no green wire.
