I have not run the zed for over 3 months so have had the battery disconected, I ran her today and she was a bit rough, so the question is has the ECU dropped the settings over the 3 months and how long before it learns again, 100 miles or so??

I would like to know the answer to this question. It may be the reason my Z has been stalling and running erratically lately as I recently replaced the battery as the 6 year old one had died.

The ecu resets once the battery is disconnected immediately if the battery goes flat and then is jumped started it can lead to corruption, if this ever occurs just switch off and disconnect the battery for a few minutes.

 

Have noticed when an engine is running badly the ecu updates much faster than normal, in fact over just a few minutes the engine balance parameters can change several times faster and have huge value range differences (I prefer to call them FAULTS) with 15 + percent value differences from the left and right banks.

 

Basically if you have removed / replaced the battery or worse it gone flat do a battery reset and go for a mixed drive over several miles at least so that all the rev and load options have been reached ( I do not mean high speed)

 

Its the quickest way to get the ecu up to date on the engine set up, any issues after that can be adjusted for in the normal way.

Thanks Jeff I knew it would have to relearn the new perameters, just did not know how long.
