If it starts up and revs all good....I would.
Only way you'll get good data for tuning is driving it.

I see it too. Have you tried programming the FlashScan's to read your particular Wideband?
You can do it in V8. Or the front panel. I'm thinking you have a setting wrong somewhere between the...
Pretty much!
You want the "Actual" (which is your wideband) and the "commanded" (your ECM tells you this in the datalog) to match. IF they match, you're good!
You are going to adjust table:...
Hahhahahah, I can imagine.
Ok, in the DVT, you need to put the idle speed at a certain RPM, and then put it at a locked timing. Raise timing till you get the most vacuum, then back it down till...
So, when it comes to fueling, you CAN'T start with a "cold start".
You have to do Spark/drive-ability/fuel tuning FIRST. Then you can work on Cold Starts here and there over time.
So, it may...
I'll take a look
Glad it started right up for you. That's a positive.
I'd have to see your file/stock file/Datalog w/wideband data.
You can compensate for some of that in the VE, some of it in the OL tables. Some of it in the Dynamics Table.
It all depends on the...

Go here and pay for it.
You'll get more knowledge then you'll ever need!
It looks like I've been helping you on the "E38 Idle".
I'd continue it here, as I don't want to get too far into issues on that thread which is dedicated to "Idle" only.
Timing table - Ok, good. But still take care of that adder. I'd just zero it all out. You'll probably need to remove some timing in peak TQ/high load/low RPM area. Factory sets it too high.

Ok, now to your PID selections for datalogging...
You want to look at what your foot is commanding AND what the actual throttle body itself is doing. This helps for tuning off throttle situations...
While you're playing with that file, I wanted to give you some constructive criticism about your file.
This is for a "street vehicle". And also for something that is as heavy as your SUV.
I...

Try this and see if it starts and now idles.
I, litterly, just opened your file and saw one thing,
Why is B1561 and B1652 so low?
Did you mean to shut off the PID controller? Or limit it that much? I would raise them up to 2.2 each and go...
The stock files come with a bit too much commanded timing for these IMO.
I opened up a stock file to look at it, and the area in which you are under a large amount of load has a bit too much...

If anyone could post up a stock file, I would appreciate it.
I have a truck that still has the Maggie tune in it and I'd like to flash it back to...
Yes. The shop who built this car completely redid the PCV system. So, I'm having to go through it as re-think how I want to set it up.
Adding 200hp to a stock engine really overwhelms the stock...
That’s what I was doing. I even suspected the MAF (which is what prompted me to also look at swapping the throttle body)
The car came to me with a NW 103 (which tunes like a stock TB for the first...
Solved....
So, the shop that built the car (I’m just tuning it) did a weird catch can setup.
I pulled off the air intake and the associated PCV hose off of the intake. I disabled the MAF for...
So, I’ve swapped the coil packs and the C6 doesn’t have a fuel filter
I did test fuel pressure and no issues
One thing to note, is when I start it up, if I keep my foot on the throttle, it will...
Post up the trans and engine file. So I can compare it to what I do to those.

I have a few trying to make small changes to get it to work if you need to look at another one.

I'm having a weird issue.
When I go to edit the file, the truck won't start.
It only does it when I edit the Engine Calibration. I've tried just changing other parameters in the file...
