ECMlink Innovate LC-2 help

[nice97civic]

I recently replaced my aem wideband with an lc-2. Initially I was getting error code - 4 along with a flashing 7.4 on the gauge. Turns out that was just a wiring thing and I made solid power and ground to ECU with quick disconnects. Now I’m not getting an error code (lc2 unit solid green light when powered on) however I’m still getting a flashing 7.4 on the gauge. I have a replacement sensor coming and hopefully that fixes it but has anyone else encountered a similar issue?

Did you buy the LC-2 new or used?

 

[nice97civic]

New.

 

[motomattx]

Its not likely to be a bad sensor then, those units are super picky but very accurate and pretty reliable when installed right and working, the grounds have to be near perfect though. Have you performed a free air calibration?

 

[nice97civic]

Yes that’s the first thing I did after doing the re-wire. The curious thing is that there is no error code on the unit (light is green, not flashing red) however the gauge flashes 7.4.

 

[nice97civic]

Another thing that is curious to me is that the connector to the sensor (lc2 side) is 5-pin however the sensor itself is 6-pin. Is my unit missing a pin?

 

[motomattx]

At 7.4 afr your sensor is putting out 0v and in air it should be putting out 5.0v the LC-2 is multi sensor capable, are you sure that you are using the correct sensor for what it is set for in the firmware?

 

[nice97civic]

Well. I swapped sensors and got an error. Swapped back, no error but still 7.4 on the gauge. Guess we’ll see what happens with fresh sensor. I’ll post updates then but in the meantime other suggestions more than welcome

Turns out i'm stupid and had the wiring mixed up. In any event, we're all good and logging now and its much nicer than the aem unit. Well worth the trouble. That said, i've attached an idle log and any pointers would be great. Idles okay but seems to spend more time in the 15.0-16.0 range than it does 14.7. Mods are in my profile

Not on my pc so can't look at the log, but if you're using narrowband simulation, you can change your narrowband switchover point. On my lc1, lower voltage makes the car run richer, and higher leans it out. Hope that helps.

 

[nice97civic]

I’m not simulating, I have front o2 as narrowband but I’ll make sure in that case sim isn’t checked

One thing I’m having trouble getting in line is airflow per rev. I’m somewhere around .32. Thought maybe this was because of cams but further reading says cams should really matter. Fuel pressure is 42.5. Do I need to raise fuel pressure to get this in line?

 

[habitatguy187]

Your profile says that you have 560cc injectors but you're set up for....this?? And set the fuel pressure on the regulator to 43.5psi for simplicity's sake since that's what injectors are rated at.

Shoot I didn’t update profile for new injectors. They’re 1000’s

Profile updated

I wouldn't worry about the airflowperrev too much as long as the car is performing fine. Basically i worry about the wot tune first and foremost then work on the drivability after that.

 

[nice97civic]

I’m with you on that. Speaking of wot, I’m experiencing some serious delay with the gauge. Say I mash the pedal and get into boost. Gauge reads lean then doesn’t read a rich reading until after I let out of it. I have fresh sensors I can swap but it’s hard when not actively logging to see what’s what. Is this typical?

 

[habitatguy187]

A few millisecond delay is normal but a whole second even would be way too slow. It may be possible that the car is just actually running lean during a pull

 

[nice97civic]

I’m running wastegate pressure ~16psi spring with no mafcomp adj at 500+ mafraw. Everything is flat 500+ and forward. I’d assume that’s plenty of fuel but I’ll have to log some pulls now that the innovate is logging and the aem isn’t a friggin guess.

 

[habitatguy187]

You got the wideband so you don't have to assume anymore.

The problem is, all of our calculations about fuel delivery are based on assumptions. We assume that the fuel pressure gauge is reading correctly, we assume that the 255 is working properly, and we assume that our injectors are what they are rated for.

I had all the math for my tune worked out perfect but when I went for a drive, it was actually running rich af. Super rich.

That's why I did my wot tune first (calibrating the fuel system by making fuel pressure adjustments) then do the idle and cruise later. I'm on SD though so it's obviously different than a mas.

 

[nice97civic]

I have fmic and sd setup waiting in the wings, just haven’t felt like taking it apart again recently but I agree. I’ll get a wot pull in now that the wideband gives me accurate logs and go from there

Revivng this thread as im having the exact same issue. What did you correct on your wiring to fix the issue?

 

[nice97civic]

I wish I could remember. I believe I was taking a signal wire from the ecu at the wrong spot.
