Read my log please!

2g automatic. Profile is updated. Coolant temp is stupid high with fans locked on. Since ive put dsm link on car, its been smoking white.

This is an idle log.

Your wideband is wired to the front o2 pin on the ECU and you're not using narrowband sim. The ECU thinks the factory o2 is still there so it's dumping fuel into the engine. You need to enable narrowband sim or wire it to a different ECU pin. Is the actual sensor installed in the o2 housing?

read up (ecmlink wiki):

EDIT: actually I just looked at the raw lc1voltage and it's cycling between 0-1v...how did you wire up your wideband? YELLOW wire to ECU?

I have the wideband controller hooked to the downpipe.

I had a shop wire in my LC1 to my ecu. I assigned a pin for my wb, and simulated narrowband and it threw everything off. Was running 30%ft after. I changed everything back.

 

[c2ypt1c]

Okay so it looks like the LC1 is spitting out a narrowband signal, so either the factory o2 is still wired to the ECU and you erroneously assigned the LC1 to that pin...
OR
the LC1's yellow wire (narrowband signal by default, although it can be reprogrammed with LMprogrammer) is connected to the ECU.


I'm leaning toward the former of the two, in which case, there should be a wideband signal (LC1's brown wire) connected to another pin, probably the RearO2, which you should reassign the LC1 to.

 

[Kdouglas89]

So, assign my WB to the rear 02, and simulate narrowband again?

 

[c2ypt1c]

No need to enable narrowband simulation, because the FrontO2 pin is receiving a narrowband signal already.

Try reassigning the LC1 to the RearO2 pin and post a quick idle log, we need to find which pin the wideband is wired to.

 

[Kdouglas89]

Swapped ecu pins to rear o2. adjusted deadtime to 555 to make my trim as close to 0 as possible. here is log. Anything else look off?

 

[c2ypt1c]

Can you please capture these values:
List of Values to Log

Also, you assigned the pin to the rear o2, but you forgot to capture the LC1! However, just looking at the rearO2 voltage, it looks like it's not recieving the wideband signal. So this means the LC1 is probably wired to something else. Try the mdp pin next and repost a log with all values captured.

Any updates? I got so wrapped up with the wideband I forgot to mention - to help control the coolant temp, try increasing the coolant offset to 10 or 15 (on the "Dash" tab). This will hopefully kick the fans on sooner but it might not be enough. Keep an eye on your coolant level, you might need to add some distilled water to it...
