I have only seen the crankfire setup that McMark was selling from Original Customs. With that said what is the adv to running the cam sensor?
If it was easier to install/cheaper big a significant amount/better signal/easier to setup I might entertain the idea. Are any of those advantages present? Also, I know Al Kosmal is currently working on a T4 - EFI setup.
The advantage is that I like to over complicate things An objective is to get the best economy (especially in town) and lowest emissions I can. A cam sensor let's you go full sequential for spark and injection which in theory can give a little better driveability and economy at lower speeds, reduced emissions, and smoother idle. I know going sequential isn't going to gain me that much, but I like this kind of challenge.
The descriptions for Marios' old NLA cam sync sensor says it must be used with a crank sensor. I'm not sure if the same will be true for the new one which will have a trigger wheel instead of flying magnet. If it were possible to get by with just a cam sensor and no crank sensor, you wouldn't have to drop the engine to do the conversion. I guess that might simplify the install regardless of spark and injection mode.
Mario's cam sync is working togeher with the crank sync only. But you can run a missing tooth sensor in the dizzy for sequential ignition and fuel, so no need for the crank sensor. The dizzy sensors are also much easier to service if the sensor is failing...
