Hi all,

I have an 07 plate WRX STi Spec D with 37k miles. My PSi3 ECU reader has been in for nearly 9 months now, and has no fault codes showing - historic or otherwise.

The car seems to be running fine with no problems, but would I gain anything from an ECU reset which I can do via the PSi3 ?

I guess if I did this from cold the first few miles may be a bit lumpy as the ECU learns etc, but would doing a reset actually achieve anything?

 

What are you trying to achieve with the reset?
It will clear the fine learning knocking tables and IAM will go back to 0.25.

 

Resetting the ECU won't do anything positive / helpful as mentioned above........
