Lexus / Toyota tuning

Post by slewinson »

Hi guys, just wondering if anybody has had experience remapping any recent Lexus ECUs?

I am about to pull the trigger on a GS250 F-Sport and am curious what can be tweaked.

I haven't done any petrol models but been mucking around with the turbo diesel stuff which I believe use the same controller...

Do you know what calibration file it is guessing it will be something like 89663-xxxxx

Will need to wait till I pick it up in a week or so before I can use techstream to have a look. What software do you use for the tuning?

I have not considered fiddling with my other cars because they are hybrids (CT200h and RX450h).

For virtual reading/writing I use bitbox, for editing I've been trying to identify map out files myself & create xdf's.
But for ready made mapping bitedit would be the best bet!

This is the potential tuning subject. Would love to hear if anybody has actual results from playing with the 4GR-FSE. Will try to get online to it and see what cal is in there.
Initial impression is pretty good but I think that there is a bit of margin left by the conservative engineering types at Lexus. with 12:1 compression I wonder what E85 could do... :driving:
