88 Ram 50 2.6L mt, have tried everything but replace ECU to get consistent lower rpm, low torque performance. Rebuilt carb and distributor, new plugs, wires, TPS, O2 sensor, coil, checked for vacuum leaks, checked temp sensor. Still pings and bogs down sometimes usually in higher gears when asking engine for more power. I've got a "new" Cardone reman ECU. The Dodge shop manual doesn't spell out a replacement procedure. Is it simply unhook battery, replace ECU and re-hook battery? Does the "computer" need time/miles to relearn the engine inputs/feedback? Please advise and thanks. Randall
