Exclamation ECU Reprogramming

Dear all,
i bought LS460 2008 several months back. it has an pcs light illuminated and due to this, my cruise control also doesn't work. i am thinking to reprogram the ECU and remove the PCS functionality from my vehicle. do anyone of you have a clue about this if it is possible or no ? or is there anyway to completely disconnect this PCS function from the vehicle ?

i really appreciate your responses.


Thanks
Best Regards

Default Hacker reprogramming ECU NCU

My situation is different from yours but I too need to find someone who is an after-market "Tuner"/ "hacker" who knows his or her way into the Lexus ECU ...
I have a newly installed aftermarket gas tank (Long Range Automotive (of Australia)- HB-12-17). It is 150 liters i.e. 39.6258 gallons. The stock tank is 25.4 gallons. The Distance To Empty (DTE) is now not working correctly.
I need to find someone who is an after-market "Tuner"/"hacker" who can change the programming which is factory set for the stock tank size at 25.4 gallons to my new tank size at 39.6258... The specific vehicle is a 2005 LX-470
Any information or assistance will be much appreciated.
With hopeful regards, Joshua
