Hi there..

Pulled the "main ECU" fuse on My '93 NA manual yesterday to reset the ECU. After this I continued to change some gaskets in the coolingsystem.
Put the fuse back in today and it started up right away :). BUT the engine dosn't feel as smooth as it used to?

Maybe it's just Me, I don't know.. It's only driven every second week, so it's hard to tell..

Got the idea that after importing the car and thereby changing to different fuel, it would be best to reset the ECU for optimal performance?

is it auto or 5speed.. its going to have to relearn your driving pattern again if its an auto. it will need to set a new fuel trim either way

The ECU's just adapting to the fuel map. Drive it a few days and it should be fine. Normally it only takes around 15 minutes of idling, but give it a few days.

Thanks for the help guys!

For your information it's a 5 speed J-spec.

Fuel should be fine, as it only get's top dollar gas :)

Will put some miles on it the next cuple of days and see how it then feels.

Besides that it's an absolute joy to ride! Haven't smiled this much since I got My drivers license hehe..

Update.

It feels a little bit better now but still not as smouth as My other Sup. A stock 93 NA auto J-spec (can't even feel or hear the engine in this one).

Maybe it's a bad battery og alternator? It can't hold op power for more than 2-3 weeks at a time. Will check this in the near future.
