EDCMatt - Do you think it is possible I just didn't get the tables tuned well enough since I didn't spend time on the interstate?

Also, what about the fuel pressure being low? I can try a second...

Ok. I'll do that tomorrow afternoon.

Ok, some follow ups.

BlindSquirrel - Thanks and that is a great point I killed the codes for now and did a log (attached) and it looks good. HOWEVER, I've had a bunch of logs look good and then...

Thanks for the replies. I'll double check this afternoon but I think the ground on this is just grounded. I didn't think it ran the heater ground back to the PCM but I will verify 100% tonight. ...

The heater codes are due to the waiting for the heaters being run straight to key on ignition vs the PCM. That's the way the BP Automotive wiring harness is set up. I've confirmed that they are...

I'll go through some of the logs tonight and see if I can catch a good example.

What about the O2 cycling in the logs. Does it look normal? I was expecting more rapid swings.

The other thing...

Keep in mind that this thing will run perfect for 20-30 minutes then go south usually

And it's always the same. One o2 goes lean and it starts dumping fuel so the other one goes rich. The...

The sensors are GM Genuine Parts 213-1702 Heated Oxygen Sensor from amazon, so a chance of them being fake I suppose.

The heater codes are because the BP Automotive wiring harness is wired with...

Background: Gen 3 5.3L LM7 out of 2005 silverado in a 2007 Jeep JK Wrangler. I didn't do the swap so I may not have some details on the components. Conversion is using a BP Automotive harness.
...

I had the diagram, just didn't realize that they were PWM and monitored by the PCM. I have the right connectors to add them to the PCM Harness.

Thanks for the help!

I'm using GM Genuine 213-1702 sensors. Which is what the BP Automotive Wiring Harness says is required, however I don't know who did the tune (attached). How do I check in the tune? I will say that...

Guys,
I purchased an LS swapped JK Jeep Wrangler. I've got a rough idle and constant O2 Sensor failure codes. I've replaced the sensors and the heaters on them are wired directly to the ignition...

I can hear the fans. A few days ago I did add some coolant (the message came up on the dash). I used the purple coolant that is supposedly for our cars and with 50k miles on it when I got it, it...

Thanks! Good information!

Ok I tried #5 and its probably got as much power as we are going to get. It is head and shoulders above the OE tune. I had a motorcylce beside my who was annoyingly reving his engine so I punched it...

Ok. I'll give 4 and 5 a try tomorrow. I am Leaving town Sunday in a different car and I'll be gone a week so I'll be out of pocket a while.

I realize Torque and HP maximums do not translate to how...

My car was fast before and the OE Tune only made it slightly better. It had a little more aggressive tone (barely noticeable) and a little more power. The tires I had on it when I bought the car were...

log file

The ECT is moving in to the red on this one even when I'm just cruising at a steady estate on the interstate. Not even spirited driving

Ok. I'll give that a shot. In the one I uploaded it was supposed to just go back to the first one you sent, but ensuring that EVERYTHING was copied, which I didn't do the first time.

This one should be a closer match to what you sent. I can load it tonight and try it out.

Note that there are a lot of differences between that one and the test one that is likely leaving a lot on...

Ok I need to sit down tonight and start over. There's a couple things I need to fix in the tune. I'll do that this afternoon

Latest tune.

I haven't tried this one yet, but I think it'll fix some of the issues you saw.

Smog isn't an issue here. There's not a county in this state that does any sort of emissions testing.

Also what's do you mean by uncooperative? The boost clearly came up from 8-10 to 15 psi. That is giving it a big bump already.
