I need help with a toyota rav4 software

[tranzavanza]

Hello guys

I need your help on this one .
Does anyone knows what I can do to correct the firmware on a 2002 toyota Rav4 ECM. I've been doing some research online and appears to be that the 2001 -2003 RAV4 have a problem with the ECM or ECU and can be fixed with some kind of update to the computer.

Does anyone knows what I can use to repair mine.

Please let me know and thank you very much in advanced.

I had the same problem on my 2002 Rav4, Toyota released a new ecm calibration couple of years ago, but it is a hardware problem eprom inside does not keep the calibration flash.. Anyways Toyota extended the ECM warranty on the 2002-?? Rav4 to 10 years 150k miles.
