: 2004 ARC vs AERO

15th September 2004, 09:22 PM
I got a great deal on the 2004 ARC. I plan to upgrade the ECU to the 2004 Aero. I have gotten two different stories from the local dealers. One says the only difference in the motors is the ECU and the other says ECU, fuel injectors plus other difference. Does any one know the real answer

It's just the ECU software...
