TRAC/ECU UPDATE IN SAN DIEGO

The Lexus people should and probably will warn you'all that want this ECU thing that it is NOT REVERSABLE .
And the word is its really not worth messing with. This ECU thing will not make the IS300 perform any better.
In alot of cases it's made the cars sluggish, or made the cars shift alot harsher. IE...slamming into gears.
Just thought I'd let you know.
Like the old saying goes... If it ain't broke don't fix it

mkaufman ,

I didn't mean imply that people on this forum felt the sluggish problem. I was speaking of the folks that had the update done at Hendrick Lexus here in Charlotte.
By all means if you aern't happy with the performance of your car change it.
Thats your right.
My wife's car is one of the first sold here in the states. We got it June 27th 2000.
IMO, the car has it's own characteristics.
I warned people here on this forum from the beginning that the IS300's throttle doesn't need to be Stomped On. Rather a quick squeeze of the throttle gives you the same results of stomping the throtle.
As far as any of the other complaints seen on this forum about transmission problems we haven't experienced any. Thank Goodness!

We are going on 14,000 miles.
