E4OD takes off in 2nd gear?

I have had my 97 cc psd for over 2 years and didn't know it will take off in 2nd untill my 17 year old son asked me if it will. He said its an E4OD feature so I had to check it out.
The first thing I noticed is shifting from park to drive I feel it engage first then, still not moving shift to 2nd and feel it shift to 2nd.
It takes off much smoother without spinning so I think it will be nice this winter.
I did some searching but didn't find any details just bad trans stuff.
Is this a hidden secret?

This is a trait of the the automatics. You can start in second gear to reduce torque to the rear wheels in a slippery situation, and then if your still getting the one wheel spin you can slowly apply your parking break to increase drag on your drive wheel and force engagement of the wheel thats not spinning. Just another old school driving tip!!

Everything I've had (mostly chevys) would start off in first no matter what but I think it will be useful.
Now I'd like to figure out how the trans computer works and why it shifts to OD at 35 mph sometimes for 100-200 feet then back to third. Also how I can get the T/C to lock sooner when It's cold.

it does that because it is trying to optomize its economy ratings, and does not feel a load but then instantly feels drag again and shifts back to 3rd

make a TC lock up switch lol

The computer does not allow lockup until the trans reach's a preset temp. A custom burned chip can change when and how the trans shifts including when it shifts into od. The trans taking off in second is just manually overriding the computer.
