It has been delayed because we are working on bringing the cost down and making a few minor changes.
In terms of the TT ECU, it will require a retro-fit to any existing TT ECUs. If you don't have a TT ECU yet and want to order it as COP-ready unit, you must let CJ know in advance so that we can make the necessary changes.
In terms of installation, it will be plug-and-play and will require coil packs purchasing seperately. We are still working on some minor changes and on the documentation. Once ready, I will upload the documentation so you can see exactly how it all fits together.
