Hello to All!
This is my first post here. But I'm regular reader since my join date.
I'm from Ukraine and my native language is Russian. So excuse me for my bad English.
I've made little research about this thread and want to share.
Using OBD-cable and ecuExplorer i've wrote the logs of TCU standing still with the engine switched off.
Then the logs were processed in MS Excell. The chart below was received as a result.
My conclusions:
1. Yes indeed, in the "1" interaxle clutch gets more "preload" compared to the rest of the positions of the selector. The graph shows that all the lines were merged into one except "Transfer Duty Ratio (%) 1", which is much earlier and sharper aim "up" meaning a higher degree of coupling block.
2. Somewhere about seen that the maximum power occurs at block 75% throttle opening. But based on the resulting chart, this value is 60% for the "2", "3", "D", "R" and 37% for "1".
3. And of course as a lock-up clutch for speed and slippage my small study did not show.
And note please that this is true for Subaru which is manufactured for Europe market.
Please If you have any questions or remarks post me.
I've wrote this article in my journal in one social network for car owners.

This automatic translator may be is even better then my English...

second. I stumbled across some info that made me doubt myself. For this year model I read somthing saying that to lock it instead of taking power away from the solenoid you have to add power to lock everything up. Is this correct? If so can I just wire up any 12v source into the wire via a switch to have to lock up?
