another problem would be the tachometer (if your car has one). the MAP type 4AGZE uses a DLI system (distributorless ignition system)... this the igniter puts out a totally different signal compared to the usual dizzy. to remedy this, there are aftermarket tach adapters which you could use (i.e. MSD). Or if your into electronics you could make your own using some capacitors and a regulator.
likewise, check your speedometer if its the electronic type or the cable driven one. if i'm not mistaken, the MAP 4AGZE has an electronic speedsensor... so you'd need to convert your speedo to accept the eletronic signal.
