How to Reset ECU

[Mr Revhead]

ECUs are constantly adjusting themselves within their set parameters.

resetting ya ECU does nothing that just driving it cant.

when you clear it it wil clear the most recent adjustments. thats why it feels like it goes better after a short drive, as its actually running worse at start up and then adjusts its self back to where it was.

there is NO reference in ANY toyota service manaul that says anything about resetting an ECU except for clearing fault codes. nor do TRD suggest such a thing when fitting their parts. in fact the only place you will ever find reference to it is on the net.

i also have down a few dyno runs unpulling and resettign ecus.

without fail everytime the first run or 2 after the rest is down on the initial run, and it always restores its self back to within a coupla hp of the first one.
