whats the diff between ecu and ignition system?
An ECU (engine control unit) is the ignition system and the fuel controler all rolled into 1 unit.
The aftermarket fuel controlers are add-ins to the system, and will work with the aftermarket ECU's, but to do so would be a little confusing, as the signal comming out of the aftermarket ecu will be different than stock.
The $600 - $800 range is a little closer.
