i want to reset the invecs / auto trans on my 97 vr4 type s. is it just a case of unhooking the battery for a while?
if so, how long, which terminal [- or +] and does this cause any other problems?

Yep, just take the negative battery lead off for about 5 minutes. Make sure you've got your alarm/immob disarmed and if your radio is coded, make sure you've got the code.
Shouldn't cause any 'problems' but expect the car to run a bit rough for a while and the gearbox to change gear harshly for a few hundred miles - this is caused by the engine and gearbox ECUs 're-learning' the car's characteristics. :thumbsup:

Disconnecting the battery in my old car a 95' Diamante (with invecs-II) caused a few problems, for a start its idle was reset to about 300rpm so it stalled once it was warm and the auto-choke was off. The gear changes were terrible had no drive in 1st whatsoever, in the end had to go to a mitsi-dealer and get it re-learned and reset the idle (cost $30 odd).
