INHOCJP, doug_999, I stand corrected....... I am.........................ashamed.

Part number is also the same on the 01; the debate is over the calibration. Bitkahuna and RealMarty did back to back comparisons of Marty's 01 GS430 in which both drove the car with the stock ECU and the L-Tuned ECU. Despite the same part numbers, both concluded that the programming differs (favoring the L-Tuned version, of course)!! This was pretty much the definitive test, since to that point, no other members had done such a back to back test (this was still in the 01 model year).

Shame on you moretorque for not knowning about the perforated leather seats

I also did the back to back tests on my 03 GS and no diff whatsoever. A buddy of mine knows a Toyota drivetrain engineer in LA and he laughed at me (meany) and pointed out that the GS430 already has the ECU. He was sure about this for 02 and 03. So for 01 who knows.

To be honest, when I put my ECU in I swear I felt a difference. But after having the impartial judge (my wife who thinks its funny that her RX300 has better steering than my GS) test the car and then switch the ECU back and forth on me, there was absoultely no difference. I'm pretty sure the difference I felt was my wallet being lightened. However the GREAT guy I bought it from who shall remain nameless (see Steve, I told you I would keep it a secret), has offered to give me credit on it.
