** UPDATE: the production Dates May 2006 through April 2007 scion tc ecu will not be able to reflash back to stock map. learned it the hard way today. the dealership tried to reflash twice and failed. called up corporate toyota, the response was also negative. so the 07's are considered "2007MY" what ever that means. if you got the ecu reflashed, there is no way to go back, other than another ecu.

 

lol sounds like a pitch to make money off of you haha...try another toyota dealer.....

 

That sounds about correct.

 

Nope you can't go back to stock. When I had my supercharger I could had to buy a ecu at tHe junkyard.

 

You still have to hop two pins on the OBII port after buying another to re-key the new (junkyard) ECU... what has Toyota done with these damm ECU's??

 

It's easy as hell to reprogram the key.

 

so i got the junkyard ecu, looks like the immobilizer thing is locked down or something, the car wont start up. obdii communication is there. but no start. which pins am i supposed to be jumping? please help im running on the trd flashed ecu to get by right now. im also fed up with the stealership taking my money again.

 

Follow this DIY, I can vouch that it does work. I've done it first hand on a friends car.

make sure you have the lights flashing in the guage cluster. if not that means its not making contact with the pins.

LOL you're welcome. My friend and I went through about 2 hours of post searching to find that damn thread when he was going turbo from S/C. I figured I'd just bookmark it
