I've got an H22a4 in my 95 Accord EX. When I use a chipped P28 ECU it runs fine but only has one VTEC engagement. When I tried a P72 or P13 or P13 chipped it idles way too low and just dies out. I want to get both VTECs to engage. Anyone have any ideas? Oh. I did read somewhere before that some wires on my ecu harness needs to be switched around to work? Something with the EGR? But I'm not sure if that is the problem at all. Thanks for any ideas or help on this.
