EDIT July 23, 2014 - Good and Bad results from test drive yesterday. Good - The cheapo spare ECU runs great! Bad - It also throws the P1101 code, so no luck resolving it yet.
According to Tom Shiels, "some ECUs throw 'P1101 - Neutral Position Switch error code' and some do not. It is not a science." I guess either you get lucky or you don't... I am unlucky in this category. There are a few other wiring shenanigans to try to get rid of this pesky code, but I've opted for just trying a different ECU. If it doesn't work, at least I'll have a back up ECU, which is a nice thing to have anyway. I did not want to just get the same year/model ECU as I already have - I wanted to get a different one to make sure I had at least something different between the two ECUs.
I found this little unit on eBay for only $38 + FREE SHIPPING. Wow - how could I go wrong? That is cheap considering others are around $120 or more.
The part # was not the same as my 2001 ECU, so I called Subaru and they confirmed the two were compatible. The only #s off were at the end. The 2000 Legacy ECU had an additional "RA".
2001 Subaru Legacy M/T ECU code: 22611 - AD86F
2000 Subaru Legacy M/T ECU code: 22611 - AD86FRA
According to the Subaru dealer, the last two digits don't matter. I replaced the computer and the van fired right up! Now, I need to drive it for a good 100 miles or so to see if it throws the P1101 code as well. I'll report back soon enough...
