Last week I started working on a tune for my upcoming 80E swap. I started with my current tune and swapped in a stock 4L80E segment (trans calibration and trans diagnostics) from the same year/make/model as mine but from the 6.0L 2500. Then I adjusted all of the shift speeds for my gears, switched off a few of the trans pressure faults for the MAF codes (I'm running speed density), and that's pretty much it.

Are there any other trans settings that are a MUST to change when doing the swap? I want to get it up and running safely first, then start to tweak the shift points, pressures, etc. as I drive it around and learn how it behaves.

My 80E is a typical built unit, internal dual feed, drilled separator plate, billet parts, high energy clutches, etc.

 

Are you using EFI live?

 

Sure am!

 

Disable PWM on the TC

Set shift times to 0

Start with stock base line pressure settings, will need adjusted based on your converter and preference.

0 torque management

 

Are the 0 shift times, 0 torque management, and disabled TC PWM settings required to get it running safely?

My intention is to leave as many settings stock as possible, changing only the settings that need to be changed for the trans to function correctly and safely. And then once I have a feel for how it behaves with the stock settings I'll start to tweak things incrementally. I've never done auto tuning before, so I want to start with something I know is correct (like the stock settings) and go from there.

 

Use an 80e force motor table.

 

I really hate to mention this, but you come off as an argumentative member who posts treads asking for help and then don't want to accept the advice. You are probably best off researching on your own and come to your own conclusions.

Is your trans stock? NO. Then why would you think stock settings are correct or safe for this application? Torque management is not needed at your lowish power level with a built 80e and will confound proper trans tuning. Turn off pulse width modulation for TC clutch application so you don't risk burning up your expensive converter. Shift times are recommended to be zero to turn off adaptive shift learning which will be throw off by the shift kit you installed. There could be some other parameters I'm forgetting but those are the major ones off the top of my head.

 

Thanks for the help.

I try not to take people's advice without fully understanding why they are making such recommendations, that is common sense. Accepting the what without knowing the why, especially from strangers over the internet, is not very smart and can quickly get you in trouble. Many people like to throw out advice without fully understanding the issue at hand, or without providing reasons for said advice. Some people are just lazy or don't want to fully explain their reasoning. So yes I may come off as argumentative, but I'm simply seeking reasons and further background knowledge. You threw out several suggestions for the tune, but I'm not going to blindly apply those to my tune without knowing why I should use those settings. I applaud you for explaining the reasoning behind them, most people don't. I did search on this for awhile but did not come up with much, it was mostly information on advanced trans tuning.

 

Any good links on more good trans tuning info?

Smokeshow, wouldn't the segment swap have the 80e force motor part already right?

 

I find the xls and instructions in this link helpful.

Tool to help tune A4 shift points...

Nice to visulize what's happening when.
