Hello guys...

I live in the middle east...

I need the new ECU calibration for my IS200T...

I told the dealer here they told me there's no calibration for your car but I have seen this L-SB-0001-18 before I told them....

And I give them a copy of it 😒

They told me that.... We are in the middle east we have different ECU 🤣.......


Since that I don't trust our dealer anymore...



Please if you have any idea how to get the new ECU calibration.... Easy and cheapest way....

Because I don't have Techstream, I don't have the cable.....and I don't have TIS account


​​​​​​..... If you have any idea how to get all of those things please let me know....



Good luck everyone 🤞

 

why? is the ecu destroyed and you need a new one as the car isn't running? if not, why do you want to update the software?

so that seems to be solely related to emissions. unless you are particularly worried about the emissions of the vehicle, i don't see a reason to update the software/recalibrate the ecu.
as far as i know, this hasn't been done to my car and i have the same 2l turbocharged engine that your car has. i'm relatively confident that it would be notated in the service history on the lexus owners site if it had.
if you can't find a dealership to perform this, i wouldn't consider it the end of the world as your car ostensibly runs fine.
