Interesting so are the ECUs programmable now? This was never the case before.Even the new BMWs are much harder to tune.
Yes. When you and I started on these forums respectively it was definitely a pipe dream. But enough time has passed now, technology has caught up, and some folks have put enough time money and energy towards making a tune for Lexus ECUs now. The BMWs are still more tuner friendly than the Lexus's but its not impossible anymore which is good.
Didn't know that they are harder to tune, but I believe it.
