Hello, I had a question in regards to running aftermarket ignition coils on my 07 civic si. I already had my ecm reflashed thru you guys, now i was just wondering if aftermarket ignition coils(okada racing coils) would be okay to run with the reflash. Thanks in advance for your help.

We don't change any of the ECU hardware. If the coils work with the stock ECU, they will work with the reflash. However, be very careful when considering any change to the ignition system with regard to electrical interference.

Honda has spent a lot of time and effort making sure that the ignition system works well and does not cause any interrence to any other component in the vehicle. There is little need to change anything other than the heat range of of the plugs at high boost - the Honda coil on plug ingition system works very well.
