I'm just wondering if a performance ECU chip for the second gen IS250 exists. Want to do something about that lag between first and second gear while in manual mode.

 

there is no "performance chip" for the 2IS.... there is about 500 threads on it in this section

 

There is an ecu reflash but its not compatible with our ecu. Only japanese ecu. I think it was developed by toms.

 

Read my signature...much better option.

 

 

there is no chip but MAP-ECU maked a piggyback for the isx50.

 

really? does it do anything? I hate how our ECU can't do much on it. But then again there isn't as much aftermarket support compared to the ISF either soo... ya go figure.

 

its the same on the ISF as well. im sure had these cars had more performance demand somebody wouldve done a stand alone but there isnt sadly enough. you can take a look at any of the 50 threads the ISF guys keep hoping for engine management but it aint happening. it hasnt and im about 99% sure it wont.

there cars basically just are what they are
