Dear all ,
What kind of tuning chip fit to the lexus isf

Can I have a list of chips names

 

Such a list does not exist. There are no legitimate options for tuning the ECU on the IS-F.

 

Nothing on the market for the ISF!

 

yep no tunes for the toyota ecu... Your pretty much stuck with intake/headers/exhaust which seems to add a decent amount on these cars even with stock ecus. Other improvements such as lightening the car is also available. Last resort you always have the option of running nitrous

 

You have another 40 HP waiting with exhaust and headers . Dont waste your time with intakes.

 

I believe the jdm versions can be tuned. Novel and Sard are the only two that I know of.

 

its a shame that no one has been able to crack these ecus I feel that there would be so much potential why is there no LEXDATA like there is HONDATA.

 

Because Lexus Corp does not want you fooling around with their cars. Simple as that.

 

Lexus ECMs were difficult to crack ever since the 90s, and is even more complex today. After the so-called 'unintended acceleration' issue, Lexus will never allow anyone to fool with their ECM. Huge liability on their part, even if you are the one dickin with it.

 

our ecu's do very well with accommodating to bolt ons. There is no tune. The engine ecu is also connected with the tranny ecu. You start messing around and things are liable to f up.


Everyone will tell you, if you want to tune you need to look at a different car.

 

It appears bolt on isfs are able to hit high 11s and low 12s. With a 100-150 wet shot low 11s with high trap is possible.

Even without a tune, I would be happy with the above.
