I have an innovate LC-1 wideband o2, and it either isn't set up right or I don't know how to read it correctly. I would appreciate it if someone could look at the a/f's from the attached file and tell me what you think. According to my stock o2, my a/f's should be on the safe side at .94, but my wideband bounces all over the place form 10.5 to 12.5. Am I only supposed to look at the low spots, or is something wrong? Any help or advise is greatly appreciated. Thanks

Sounds similar to the problem i'm having. I haven't driven my car yet, but @ idle my a/f ratio jumps from 14.5 to 16.5 constantly. I would imagine driving to vehicle would produce the same results you're encountering.

At idle, it should move up and down like that. it does on all cars.
you should worry more about when your at Wide Open Throttle, make sure its in the safe zone (low-midd 11s i think)

At WOT is when mine jumps around. Is it supposed to producs a flat, or somewhat flat line? Maybe I hooked it up to the wrong analog out because I read in the LC-1 manual that analog 1 and analog 2 are different. It pisses me off that I bought a wideband, and I'm still using the stock o2 to tune. Thanks

I think you are wrong, the stock o2 should jump around @ idle but the wideband should not! The wideband display is going 14.4-14.6-14.5-14.6(which is normal) while the signal the ECU+ is reading from the wideband is going something like this 14.3-16.7-15.2-14.4-16.3-14.9, ect...

My car at idle bounces between 14.5 to 15. At wot its at high 10s and low 11s. You really should not see 12.5 at wot on pump gas, thats too lean. Also I think it depends on the gear too.

usually on a 3rd or 4th gear pull my WOT will stay between 11.0-11.2

I talked to Tom about the LC-1. The settings for the LC-1 and LM-1 are different. Tom told me I had to calibrate the LC-1 with the software that comes with it. Maybe he can chime in or Email him, he's very repsonsive.

EDIT :

Here is the email Tom sent me about this very same subject.

The LC-1 outputs a different voltage on analog 2 than the LM-1 does. So, when you get it in, you'll want to use their programmer software to make the outputs the same:
set it to "1 volt for AFR 10.0" and "2 volts for AFR 20.0". Then Update.
After that, you'll be able to use the LM-1's calibration that's built into the ECU+.

I've wired the LM-1 so that it uses the same power source and ground as the ECU+ in an attemp to minimize the bouncing of the a/f ratio seen by the ECU+ but I haven't had any luck while my setup the meter displays 14.3-14.7 while the ECU+ seen the voltage and translates it into 14.0-15.6

Anyone else having a similar situation?

OK you lost me because in your original thread you said you have the LC-1 in this last thread you refer to an LM-1.
