Another stock ECU differential question...
What's the diff between the 557N and the 558M for the 1.8tqm? I'm looking to buy and there appears to be some price diff on some sites. Thanks.

Seems 557N is from a 97 and some people have said that
they dont always work in a 98-99.5 or the 98+ ecu into a 97. Best thing to do is to find a part # that is the same as what you have now.
