I'm just getting done a swap and finally at the point of finishing off the tuning. I did a 4l80e segment swap and my hpt file currently has a stock tune file for the trans. For just starting the base tuning can I take all the setting in my original 60e tune file and copy/paste them over to the 80e file? It's close to an identical stall convertor so I figure this may be a good place to start. I think that I possibly may need to just scale some of the tables based on gear ratio changes, but otherwise is this a good methodology?

 

If you did a segment swap then you're done. You need to segment over the Trans and trans diagnostic sections.

 

Check out the end of this file here. I used bluecat tool to dial in the shift points. Just put in the new gear ratio into the bluecat tool and copy the tables over into HP.

Yes, I segmented a stock 99' 4l80e truck segment onto my 99' 4l60e fbody tune file. So I have stock 4l80e truck shift settings in my tune now. I'm trying to ask if it would be a good starting point in the tune to copy my modified tables, from my 60e tune, over the factory truck 80e tables.

 

Exactly what I am trying to accomplish, thank you!

 

Sure thing, let us know how it goes!

 

The BlueCat worked great for setting initial parameters. The first drive had solid shift points. There's definitely some finish work to do, but the tool offered a great starting point.
