Todd's advice is actually really good. Given that modern Civic's and the LGX engine both rev to roughly 7000 RPM, the transmission logic will be fairly similar. Most gasoline engines nowadays have roughly the same RPM span, so regardless of the displacement or cylinder count, the general VE curve and RPM band is applicable to nearly all production cars. Watching the tach and seeing what an auto trans does gives good insight for relevant RPM points for all driving conditions.

Means nothing unless both engines have the same HP and Tq. bands at the same RPMs.
