Also, are there Unichips available for the Yaris?

I've heard of several cars here and Indonesia tuned with those. But, AFAIK, their US distributor has no knowledge of it. Once again I am pretty sure due to ECU differences.

Yes, that seems to be the case. Open loop tuning should be far easier (as ZPI did), but for some reason looking at the Blitz'ed guys results, that doesn't seem to work too well. In other words we're really looking for a solution to cover both closed loop and open loop operation.
