I agree with Challenger & I'm in a minority here but I consider the ECU just a (coil) primary current on/off switch & as long as it ain't pulling timing like the newer orange boxes reportedly do (I never plotted a timing curve chart) that a good made in USA one is fine & the real power is in the coil/ballast (or no ballast) combo. The standard motor products LX101 was a good standby tho I bought one the other day & it is made in china now (ran OK & turned out the prob was my black FBO coil was what had died)
