The likes of Evo's, Scoobies, 200SX, etc are still considereed main stream cars in the States and Japan. So Apex built a specific ECU for them.
With the likes of the Pulsar SR20DET, Nissan stopped production in about 1995 and Apex consider it not worth while to spend lots of money developing a specific ecu for them as a lot of cars are now old and people don't want to spend money on them :roll: So they commissioned AP Engineering to design and develope an ECU for our cars. Apex gave them a map for the S00SX which they tweaked for the GTiR. They (AP E) have done this for about 10 cars/applications. That's why the Power FC is more expensive for the R.
This is what i was told anyway
