tha only real ecu test, imo, is ta be able ta try one that is "known ta be good" but not always possible ta do for most folks.... there are so many things involved with tha opti that can cause problems...
if ya had ta rebuild, was tha orginal problem found and fixed BEFORE ya started runnin' tha thing again?
like Gary recommends,, S&F is as good a place as any ta look for one.. MOST on there are good guys but there are exceptions like anywhere else... just be sure ta save all communications between yourself and other party!
