I just did this for a 4L65 to 4L80E. I'll try and remember to take a picture when I'm under the truck tonight. I was never able to get my reverse lights to work, but I got everything else to work. ...

Question for GHuggins or anyone else that might want to chime in from experience:
So now that I know that both the overall table, and the boundary table needed to shift +30 based on the suggested...

All,

I wanted to say thanks for the help in regards to EOIT. I will post logs hopefully by the weekend but the preliminary results are:

+30 on boundary EOIT reduced pulsewidth by 1ms and went...

Ok - will do! Was it the offset vs pressure vs IGN voltage table that looked different to you? I used a 2010 3/4 ton Yukon VIN 1GKZREG0AR189018 Operating System 12636005 to pull my numbers for the...

These are my current PE settings:135392

This is the ignition table: 135391

Should the advance ramp in faster at those low rpm's? Is the OEM just trying to be super safe/conservative about encountering knock? It does feel and sound much...

Yea I'm at 1.2 lambda and the engine is commanding .88. in that screen shot for about ~.3-.4 seconds? It just feels "mushy" when you're behind the wheel. Like the power doesn't really snap in but...

I know the VE isn't perfect but this spot in the log is not just EQ moving around from a bumpy VE map - this is pretty clearly transient lean on tip-in. Just curious which direction to...

Hi everyone,

Trying to get rid of a transient lean tip-in and rich tip-out effect. I don't really care about the rich tip out but the lean on tip in can be felt as kind of an initial dead spot. ...

You'll need crank, and camshaft signals - if I'm not mistaken an LQ4 has the camshaft sensor plugged in near the back of the galley - where the DOD control plugged in on your 5.3. But your original...

Thank you! That will be handy!

Google Goat Rope Garage Gen 4 VVE tuning. Watch the Gen 3 video too. Instead of multiplying the whole chart by a percent you want to correct each cell by percent difference between measured lambda...

It looks like you tuned MAF, and now you have tried to set yourself up to tune VE using the MAP sensor. I looked at your virtual volumetric efficiency chart - it looks like it went nuts. Have you...

As the subject says,

I have setup a spark advance table where I am using Spark RPM on the X-axis and Cylinder Airmass in grams on the Y-axis. It records the instantaneous spark advance using the...

Why?

If you end up with a situation where you decide to update the MAF to the newer LS3 card-style one let me know, I'm curious on an E38 ECM with those 07-09 truck MAF's how this can be done. I believe...

If you study that LS480 crate tune file, there are a lot of funky things in it. But the idle control tables are useful to copy over both ignition and fuel. They will help get a decent idle going...

Alvin that's not entirely accurate. In the 90's they were not running roller lifters - they had flat tappets and thus the profile was not the same. The advantage of the 'LS' version of the hotcam...
