ozaristov300 Occasional Poster Location: Melbourne Registered: January 2005	Re: Building an IS430 Sun, 23 January 2005 14:01 mrshin wrote on Mon, 24 January 2005 00:39 It could be possible that a Lexus dealer has the software and dongle needed to upload any changes ... Based on discussions with insiders at Toyota, the chances of this are between zero and none. One of these guys is embedded inside product engineering and even he can't get to the ECU code. He says Toyota regards this as critical Intellectual Property and guards it accordingly. If we could get to the code, we could simply dick with the input variables and parameter arrays. Of course every business offering after market ECUs and overrides would go bust in the process! To me, the most valuable code in the genuine ECU is the stuff not related to making the car start or go fast. It's the code that stops the engine becoming a hand grenade, knowing when an input sensor is sending it crap and ensuring you can drive home even after a multiple melt down. The after market ECUs dont know and don't care if something breaks. Apparently a typical Toyota engine ECU today contains in excess of 1 million lines of code. cheers Wayne [Report message to a moderator]
