So me and hustler via phone decided to hook up my lc-1 a few days ago and to say the least it was a success worked great no problems at all! untill yesterday. Now out of no where it only reads maybe 10.14 afr max. So I check all my connections and they seemed fine. Also I had made the led switch deal, since mine didn't come with one to check if there were any codes, there weren't any (so it worked fine) I changed my grounds to a nut that I soldiered the ground wires onto. The power is spliced into the ecu power and the yellow output is coming from the existing 02 sensor wire. Now I've checked my configurator to make sure its on the innovative linear 0-5v 10-20 afr and it is, plus under basic settings, the exhaust section is set to wideband as well.. what is up do you think it's my power input? or plain f'ed up sensor? help me out here I'll attach my .msq even though hustler took a gander at it. Help me out here I'd like to have some mpg again..lol

 

This is why i hate the lc1. It might be the most accurate for the price, but its filled with headaches. The AUM UEGO is so pain free. I've used both, would never go with the lc1 again unless I got it for super cheap.

 

I've been told.... Well i know for a fact the actual unit is ok but I'm thinking the o2 is fried, what are some common symptoms? Joe help me out here brain you know this too hopefully... Thanks again in advance

 

It was working fine when I pulled it out of my car. The O2 sensor should be fine for a long long time. How did you smoke the narrow band gauge?

 

Did you calibrate it out of the exhaust stream?

 

yea like three times...but it was odd when I made sure the settings in output 1 where on afr, 0v = 10 afr and 5v = 20 afr it wouldn't let me burn them to the controller and there is no real way to check if it's burning the info so who knows..... bu ti will say this when i just pull down the fuel tab I have the option to burn the settings and I usually do but again have no way of confirming burn

 

it was hooked up to + and neg only and they touched on accident so poof it died instantly

 

I also have an inline fuse with the power and I've confirmed it's not blow.

 

Whats getting that incorrect reading megasquirt or the gauge that comes with the unit?

My first recommendation is to make sure the controller is running firmware v1.0. If is not, downgrade asap, its buggy ****.

 

i have no gauge so it has to be ms and i believe it has 1.0 if not its like 1.1

 

how would i downgrade it if it was on something higher

 

does anyone think the power source is bad?

 

My LC-1 crapped out on me once, and I got a replacement a week later. I've never had issues with it since or even beforehand, so I dunno what everyone's deal is.

 

It has version 1.10 and i looked under the firm ware for it at innovates web site and they only have 1.10 not 1.0, maybe there is something I'm missing on the install procedure through mega tune.

 

1.0 you can download from their forum, someone has a link.



You sure you got the outputs from the LC1 correct, and programmed them correctly? Using AFR and not Lambda?

 

yeah first box is 0 volts= 10 afr and 5v=20 afr and yes its on afr man I'm stumped... maybe there is something up in MT... I'll download that firmware and load that in there maybe that'll change things...hopefully

 

soo the power supply point.. I called innovate and they said it pulls 3 amps starting up does anyone know if there is at least 3 going to the Ecu

 

The fuse for the ECU is 5A IIRC. So you are really stretching it.

Jim

 

ohh cool ok thanks I'm going to switch it over to the 12v cig lighter I don't use it at all

 

Quite literally I've done everything in the manual, peoples' advice here and an innovate tech..... yet still no luck on this damn thing working correctly! it is only reading 10.04-10.24 afr in megatune, I'm not getting any codes, it's warming up correctly everytime. I hook up LM programmer everything is fine, I'm close to selling it and getting a damn aem uego, please anyone with some last minute help let me know. the only thing i can think of is the sensor being bad, Has anyone had similar simptoms? thanks again
