cambelt, thanks for the info! I think it's easy to fool the newer ECU with the speed signal. I sell a number of signal converters with each conversion kit, including one for car's original speedo. It's not a problem to add one more converter that would take SP2 signal, divide/multiply its frequency and feed ABS input.
Demon, very interesting info on immobilizers. So, there's a specialized software that would generate 'resetted' dump that would bring 3UZ ECU into 'blank' condition, then allowing you to put 3 arbitrary keys into it? How about security ECU then? It also needs a special EEPROM dump to be locked on to engine computer. With some toyotas, it's enough to connect TC-E1, ignition on and leave the car alone for an hour, then in some cases security computer will be synchronized to engine control unit.
I didn't quite understand your info on LS430 6spd bug port. I know newer Toyotas accept ECU software updates available via TIS, you download them via OBD cable. But the updates mostly deal to gearbox timing settings etc etc.... not the secutity system, did I miss something?
