Hi all

Recently I installed an Innovate LC-1 wideband w/ Innovate AFR gauge into my Ralliart, it worked fine for about a week (reading from the gauge) and then I wanted to do some logging so I hooked up my laptop.

I had trouble with a serial to usb driver on my laptop, after I updated that I tried logging with LM programmer and EVOSCAN and then it all went haywire.

Now my gauge reads 7.4 flashing on start up and then when heated it basically will just give me random readings. It used to sit on 14.4 at idle (I only did calibration but not reprogrammed it).

Any ideas? I was just going to free air calibrate again and try that, but maybe someone has seen this before and can advise me please?

 

The LC-1 is the biggest pain to set up. What happened was that your baud rate got changed when you updated your serial to usb driver. Below is the link to my thread that should fix the problem.

Thanks for that.

I'm the one who replied that thread!

I'm going to do another free air calibration and change the baud rate on my laptop and go from there.
Would have done it by now but I've been stuffing around with wheels.

 

Well I fixed my setup, the terminator pin was in the "out" jack rather than the "in" jack and that solved my problem with the serial to usb not working with my laptop.

I did a reset and another free air calibration.

I managed to do a short log of my car idling and reversing up the driveway. Logged fine in EVOSCAN and worked well in LM programmer.

But it stopped working while I was driving, now it's just flashing 7.4 along with the LED.

Only thing I can think of is that I need to earth the yellow wire from the gauge ( is meant for dimming the gauge lights). So far it's just taped up.

Any other ideas anyone??

 

Did you check the fuel setting in LM?

How do you do the calibration?

 

Yep i set the fuel for gasoline (14.7)

First i disconnected the sensor from the control box. Turned power on, waited 10 secs. Power off.

Reconnect sensor to control box, but not screwed into exhaust, sitting in free air.
wait for it to heat up, then depress red button. LED came back on with no flashing.

Installed sensor into exhaust.

Then I started the car, and it was fine. Gauge reading 14.7 at idle, richened up on throttle.

It conked out about after 10 minutes of driving. Gauge just kept flashing 7.4

 

They have always been good about helping on the phone. Does seem they have some issues with thier products even though ive been lucky so far.


Have you tried calling them?

 

Hey cheers, I never thought of that.

I'm in Australia though. I'll need to work out time zones etc. If I want someone to answer me I guess.

Thanks for the replies guys. I'm slowly eliminating the potential problems first. But I did get the thing to log on EVOSCAN correctly so I must be close.

 

I've never disconnected it from the box. This is what I've done for the last 6 years:

1. Take it off the DP
2. turn on the ignition to on, but engine off
3. wait for the heat cycle, then hold the red button for 30 seconds
4. let go of button and turn off ignition
5. put sensor back on DP

 

OK I counted the flashes it made in Error mode and I actually think that the sensor itself is faulty. Only works just after calibration and after going for a while it just dies.

 

I think I'm on my 2nd sensor in 5 or 6 years. How many blinks means faulty sensor?

Did you change anything recently, like got a tune or went SD or changed to E85? I'm just curious if it ran really rich/lean causing the sensor to die out early.

 

Ok guys thanks everyone who helped out, sorry I just disappeared but I kept on trying to get the thing to work.

After losing my terminator plug during a stereo install and then ordering another one. I pulled everything apart AGAIN and put it back together, did a free air calibration. Then tried it out.

It has actually taken 6 months for me to get my wideband and gauge to work, and part of that was waiting for a gauge pod that took forever to arrive. Really glad that it works now, and big thumbs up to everybody involved.

Anyhow now I was able to get rid of that dip in the boost curve and cure that knock! *or someone did it for me
