I have a 2003 ep3 I'm wanting to tune I have a wrecked 2004 Honda Element K24 that is all wheel drive that I'm wanting to pull the ECU out of and tune will a k tuner go into this ECU to be soldered in with a jumper harness does a 04 element ECU need a ha Motorsport jumper harness? I'm new to this I recently purchased two 2003 ep3s in a package deal and I'm really wanting to start tuning these things and eventually awd one of them

 

The EP3 ECU (PND) can be tuned with Hondata KPro... the Element ECU isn't necessary because you want to convert the chassis to AWD. You are tuning the engine... not the transmission or the rear differential.
