I am lookng for some test equiptment for a 97 Merc EFI 502. Maybe a Rinda or if there is another out there that would work.

That is a pretty "stupid" engine, so scanning for codes is fairly simple. If you really want to see readouts of the inputs then you need the Rinda Diacom, works real well.

Thanks, I'll try that!
