yes. There are other settings that can override it and force an upshift or not allow a manual downshift though. I forget their labels, but you should see settings in the shift scheduling tab that...

That's for the E38 ECM and I have E78, so it won't work for me. Sounds great for anyone with E38 and $600 to spend on it. Thanks for adding the info!

Searched forum and elsewhere and can't seem to get a good answer on this:

How Many Credits to Calibrate Speedo on 2017 F150 10-Speed 3.5? A friend changed his tire size.

Thanks,

and I'm happy to help anyone one-on-one if you can handle 90% of it on your own. Just message me and mention TUTD.

6 Speed Auto TUTD without BCM and without Corvette tune.
This is a Microsoft Word document with very easy and clear instructions for you to enable the Tap-up/Tap-down (TUTD) function on a 6L80e or...

I'm using version 4.4.4. When you click on the "Normal" button do you get the chart for "Upshift Speed vs. TPS vs. Shift - TUTD"? If not, dig around til you find it. It might look like the chart...

I know nothing about the G8 shifter but I did try using the tapshift buttons from the van donor that supplied the motor and transmission for my swap. It was just a resistor tree powered by 12V but...

Is there a way in Scanner to see if/when the converter clutch is being commanded to lock?

Here's a tutorial I put together in Word format.
It worked for me; 2016 L96/6L90e/No BCM/NOT using Corvette tune.

Well if all else fails, perhaps I can figure out how to send that "message". Arduino maybe...any idea where to find a copy?
Seems the cruise control and Tap-shift systems run through the BCM as...

If I missed the answer in my search, please just help me find it.

I have a 2016 L96/6L90e with the E78 ECM and no BCM (swapped into a Squarebody truck).

Anyone know how to wire up the...

You sound like the guy to ask where I might find a guide for VVE/MAF tuning the E78. Got any suggestions on a beginner's guide? Thanks

I'm considered a smart guy in my circles but perhaps not smart enough. What am I missing? I see nothing in that link that clues me in on how to tune my MAF to a larger intake tube.

Can you steer me in the right direction to find a guide (in HPT forums or elsewhere) on tuning VVE/MAF for E78? Searched the forums and I didn't find one. Thanks

I case you didn't see it, I edited the original post to reflect that the problem was fixed with an old tune but I don't know what parameter was the culprit.

I got the graph figured out; had to log "MAP/Baro (Pressure Ratio)" instead of "Manifold Absolute Pressure".

I followed the guide you linked, attached tune and log files.

Something ain't right about the graph. It's logging only the 1.02 line so I cut the trip short. Could that have...

I have no idea how to tune MAF/VVE. I guess I'll be doing some more reading. I have the MAF Calibration/Airflow vs Frequency multiplied. With the "MAF calibration restrictor" installed in the MAF...

Intake is 4" cold air, so yes it's larger.

No idea how

Made the changes you suggested. Attached before/after tunes and logs.

ok will do that. gotta knock out a couple errands. about to write the tune now. thanks

I did go back to stock timing tables along with the other items u mentioned but haven't written to ECM yet. Found knock threshold, thanks.

The Airflow Cylinder Charge Temperature Bias table has never been touched. I dunno how they are butchered unless it's part of the changes that the gear wizard makes. Nonetheless I pulled up the...
