Classic and New Age ECU 5 minute Reset Trick

[BlackWagon]

Hi all,

Just found this excellent ECU reset trick -  takes 5 mins and guaranteed to work (Subaru factory procedure)

Apologies to those who already knew this []

Cheers,

Andy F told me that unpluging the battery and switching on say the lights to drain the last of the power from the system for 5 min would be enough to reset my STi9 if I got a bad batch of fuel etc to bring the car back to map conditions quickly

. . . . . . and then he said to do the 'quick-learn' trick (AKA Vishnu method ) to speed up the ECU learning process as Scott points us to in his first link []

Yeah I like the idea of using factory fitted connectors to do the job in 5 mins - that makes it easy to do any time.

If Subaru put the plugs there to do the job thats good enough for me lol

Heres a GREAT idea....(since i'm a spark):

Fit a switch somewhere and wire it to connect these two sets of plugs - you could even use plugs from a scrapper (both greens and blacks) then plumb them into the existing ones and reset the ECU anytime you like.....

heres a question tho why when you connect the two greens does the ac fan kick in ??lol

and as i have a tech 3 remap will i lose this if i reset ??

cheers !

[bigdavie]

anyone ??

[BlackWagon]

I'm not sure mate but depending on whether the remap is stored as the default or not I guess a reset will put most stuff back to factory standard.

If the car has been reprogrammed then no it wont but if its just a shift of the default values then probly.

Footnote: a search of the wondernet says that the ecu will default to map values as it adjusts any map due to driving conditions, fuel quality, barometric pressure etc.

Anyone else know better?

[BlackWagon]

Hmmm - the fans could be on for rolling road purposes. Handy!

Actually I suppose because they turn on test mode.
