This is a great price for this ECU. I asked the same exact question to MWR as they have a 190 ECU they sell and that is the same part number. I found it cheaper than somewhere else, no surprising with their price. But I paid a lot more than what this one is going for.
Only problem I had is, it's not ODB II, so not sure what I need to plug into it in order to read the codes if it ever throws one.
Also, Celica40, if "nothing special" about this ECU and needs modification, then why doesn't MWR tell you that when you go to their site? And now, they don't publish the number, I had to get them to tell me over an email as I'm sure they would know that you could find it somewhere else cheaper.

If I didn't have this already, I would have snatched it up!
