I have a 2004 Accord Coupe 2.4L and was wondering about a new after market computer for it. Are they worth the money?

 

Depends what your plans are... look at Hondata!

 

^^^ This. If it's a street car and you're on a budget then go with Hondata K Pro. If you are racing competitively, want something with more features, and have cash to spend then there are numerous options you can look at such as AEM, Haltech, and Motec. Keep in mind these are only worth the money if you plan on actually utilizing their features. For example if your car is strictly a street driven car then a Motec ECU will definitely not be worth the money.
