Um...I already answered your question. There isn't a lot of options here. You need a CR ignition, and the only programmable box for the CR that is currently being produced is from Vortex. It has to be programmable so that you can get the initial timing low enough so that it doesn't want to throw you off the bike.
You can also go a trx ignition with a dyna programmable box. But I don't care for the heavy flywheel.
