Thank you for your answer.
As I saw elsewhere, can I read and write remotely?
I also wanted to change the ISC settings because my vehicle is only front-wheel drive.
Both the Legacy and Forester are fuel injection settings for four-wheel drive, so if it is a front-wheel drive vehicle
Since there is no transfer of missions, etc., the number of revolutions of the ECU will be exceeded and it cannot be controlled well.
I finally found out the cause last year.
As an aside, it seems that manual transmissions require more rotational force than automatic transmissions.
A long time ago, it was equipped with an EJ-202 (AT) engine. When I started the engine with the ECU for automatic transmission, idling was quiet. However, if you drive as it is, an error will occur and you will not be able to use it.
