Hey TrevorM3, actually it's opposite Lexus/Toyota are so heavy encrypted, they write protected ROM so code can never be changed among other things they do to ensure ECU remained encrypted. Knowone has been able to hack Lexus/Toyota ecu's until now. Take the Supra for example to this day they still haven't been hack. In order to tune you Supra you must run standalone or piggyback, once done everyone knows the factory blocks are incredibly strong and Capable of huge amounts of boost. You can run standalone or piggyback on 90's car but not on modern car such as ISF. If I ran standalone I would lose most of functionality of car trans,nav,dashboard,etc.
There's been demand for tunes and several large tuning companies tried but failed to hack ecu. RR racing is planning to release tunes for RCF, GSF, and LS for now and thats not including IS350 and RC350' s and thats just one tuner. Over the next 2 yrs as other tuners begin to create tunes this segment should grow.
