i did tom that is exactly what i pointed out with the images (that there is no need to point out the knee to the pcm) if there were,...

This engine doesn't have the jumper harness like I have seen on other LS engines. It's just the sensor and the main harness plugged into that.

Thank you for the clarification. I will check the part number

I forgot what data was used but i can double check later.

Config 4 Mode 0 is where I've been focusing most of my attention since those numbers seem to be the closest to what I'm seeing, but they're all still...

LSA camshaft as in the LSA in the supercharged 6.2? The engine wont run at a 25 AFR. Usually they wont run past about 18-19AFR. If you post...

'Tune and datalog' means you have to post the tune file and log file here attached to your post so that other people can see them. It's not asking if...

I resemble that remark!!

MASSIVE SUCCESS More soon...

That doesn't make them flex fuel injectors. Your originally-built-as-non-flex-fuel '09 Silverado should have come with non-flex 12580681 injectors,...

let's start out with the basics. What do you have. 14.7 is what should be 'commanded' not 12.5 as stated above... also, post the following: ...

What's the part number on the injector?

It has a E85 sensor in line on the intake. That's why I said it was flex fuel.

Either way.. poor zone boundaries are an issue with two people in this thread alone.

Mercury is in Brawndo, then. It's got what plants crave.

Don ... look at the breakpoints. It seems to me FIC is intentionally including these very close breakpoints in the data to call attention to the knee...

Mercury is in gatorade. Be careful out there folks.

I can see that perhaps the nature of the zones is a work around (or exploit) to the software defect, but that would obviously not be an ideal...

There were only two Gen 4 4.8L's, LY2 from '07-'09, and L20 from '10-'17. Only the L20 was flex fuel. There was no 2009 4.8 that came with flex fuel...

hello and tks for the help I use a corvette style filter regulator and the fuel is a returnless system, only one inlet on the injectors H pipe......

far from linear? yeah, fic data claims flow is going backward (180 deg) i do not see backward flow in any other injector data here is all of...

Thanks, was thinking something had to change as far as parameters. I?ll be purposeful and bring the key Base tune parameters to the new OS. This...

one of the biggest areas that these 3.0l love adjustments in is timing and desired boost settings running a even torque to fuel map with the 516...

looking at one of my stock files it would seem to me that that 9 deg is about right for what stock timing maps are running it runs in config 4...

It's a bad idea to copy out of other tunes other than hard part setup type stuff.. like map scalar and offset, injector data, etc.

So yes you are fine driving it.. Just be prepared for it to stall in idle situations.

Yes that is what happens.. But every one that I've encountered this with and there have been many. Have been once in a blue moon situation. You...

Mercury is in retrograde.
