I have an 01 is300 and from what I've read, it seems like 02 is300s have a newer ecu flash or a different ecu all together. Is there any way to get the 02 info onto my 01? will a lexus dealer do an ecu flash for me? if so, do they charge a lot?

hehe.

The 02+ ECU is in fact newer...by 1 year.
And the 03 ECU is newer by 2 years.

It's newer, different but no better.
Is there any particular reason why you want to reflash your ECU?

it's not worth all the trouble....the 01 pinouts to the ecu are completely different from the 02+ so if you want to get into all that...

04+ ECU are more desirable. They included some additional user friendly features such as locking and unlocking the doors when you start the car and when you turn the ignition off.

Edited: Yeah, also 01 are less forward compatible than the other years.
