Q: I have an RSX, and i went to the Hondata website and read about the reflash on the ECU because i have a k20a3 engine. It said that i wouldn't be able to get k-pro on it (is that true too??) so that's why i was reading about the reflash. Would it be worth it??
A: On the hondata website it says the K20a3 is able to get kpro on it. http://www.hondata.com/engines.html go down to 2002-2004 (K Series) to the k20a3 and you'll see to the right it is compatible with k pro
