This conversion is designed around being able to use the stock ecu and the key feature being cost savings. So in your case, nothing would have to be done to your Enthalpy as it is compatible with my controller. There are a wide range of coil packs that have a very similar dwell time as the coils Nissan uses.

Also, one item I have been working on incorporating is knock detection. Allowing the user to see which cylinder has an ignition knock. This will allow for individual cylinder tuning.
