Using Auto Timer with Innovate LC-1

[MitchTSIAWD]

Can you hook up the Apexi Auto Timer to the output signal on a Innovate LC-1? Instead of hooking it up to the narrow band signal at the ecu, can you use a the wideband signal from the LC-1 to get a more accurate reading to tune from...

I don't believe so. Especially after reading this quote from their website:

By inputting O2 sensor voltage, the Timer can also display theoretical air fuel ratio. Since the Auto Timer uses the factory O2 sensor which is primarily designed for emissions, the readings may not be as accurate as racing air/fuel ratio monitors.

the signal coming from the LC-1 is still a 0-5V signal... it is just much more accurate.


The reason i am asking is, i am going to use just the LC-1 and remove the stock O2 sensor, since the LC-1 has a output wire that can mimic the stock narrowband sensor. This way i dont have to run 2 O2 sensors in my housing... and i figured if i can run a more accurate signal to the Auto Timer it would work much better as a way to tune.

How else were you planning on reading the signal from the wideband if the turbo timer wouldn't work? I don't see any sort of logger in your profile.

Get the gauge for the LC-1

or

I am running a MAFT Gen 2 and that will display the A/F... but its in a seperate screen, so not very tuner freindly since i would have to switch back and forth...

yeah my profile needs to be updated.

i was just trying to eliminate extra money and gauges in my car.

I just got off the phone with Apexi and the guy said it was possible. The turbo timer sees 0-5V as an input already, but he said it's recommended to reconfigure it according to the manual. One down side he said is that it is a lot more delayed in feedback vs. using the stock sensor.

So, if you don't mind a delay in feedback, go for it. Otherwise, I'd say either get a logger that can read it as an input or get the gauge. I have mine through a logger and a gauge and it's very nice.

 

[MitchTSIAWD]

how bad of a delay?

 

[snowborder714]

That I'm not sure. I would assume that the stock sensor would be a bit delayed though it, so the wideband would probably have a good bit of delay. But that's something that you'd have to test out if you were really interested in doing this. He didn't have any statistics for me.

 

[MitchTSIAWD]

you would think if it was delayed it would be just as delayed as the stock one...

Wouldn't it be the same as using the LC-1 w/ the Innovate gauge that goes with it... right?

All it is, is a Auto Timer rather than the Innovate display gauge.

The voltage will get to the Auto Timer just as quick as it would get to any other gauge.

 

[snowborder714]

The delay is something you're either going to have to try out or call them and see if they may have some numbers sitting around somewhere. But the guy I talked to had to go ask someone and they didn't seem to know that much about it, since I assume most people wouldn't do this.

 

[MitchTSIAWD]

ok.

thanks for your time and feedback, i will see if Apex has anymore detail on this.

Not a problem. Post back if/when you get some more info!
