Hi everyone,

I was wondering whether anyone can answer my question of whether or not the engine CPU needs to be reprogrammed after installing the Lexus intake or exhaust?

I know that when I worked at BMW (for 2 years), any Dinan parts installed (like the intake, exhaust etc), the car needed to be reprogrammed to account for the increased amount of airflow (for the intake). Does Lexus work the same way, or could one just install these on their own without having to get the vehicle engine CPU reprogrammed by the dealer?


If not, are there any other mods available that would require the engine CPU being reprogrammed?


Thanks.

 

disconnect battery for 10 min and you will be fine

 

Awesome, it's the same as my Honda then. I haven't looked at my manual yet, but will we need our "radio codes" or whichever security codes are needed after a battery reset?

 

i havent needed to do anything other than diconnect. also i posted a pic of my spoiler on other thread

 

Yeah I saw that, thank you.

 

Someone recently posted, they unplugged the battery and the car maintained all memory

 

That's odd, do we still need a security code or anything if the battery is disconnected to use the radio/navigation?
