KitCarlson, still fighting... Options

[McMark]

I'm still struggling to get my KitCarlson EMS running smoothly. It's a challenge when you're tuning FI and Ignition.

I read some threads on ShopTalk Forums where Jake recommends 12 degrees initial advance and 28 degrees full advance, all in at 3000 rpms.

So I dialed the ignition controls in to these figures. Checked the setting with a timing light and what's showing on the EMS monitor seems to match what's showing with the adjustable timing light. This is a wasted spark system and I've been ambiguously warned that a standard timing light "won't work" with a wasted spark system. This doesn't make sense to me though.

The first issue I need to deal with is that the car won't rev above 4000 rpms. When I first started setting this up I had the same issue and adding in advance cured the issue. I trust Jakes recommendation and so I'm looking for other sources of this issue.



Currently my logic tells me that if the system is too rich above 4000 rpms it would respond to more advance. Spark earlier gives the rich mixture more time to burn. I'll be playing around with this idea tomorrow, but I'd like to hear what'cha got to say.

How do you set the trigger "window" on the Kit system?

On the SDS you must first set the window (magnet position) in the program
Note that MAGNET POSITION and RPM IGN (timing) are totally separate parameters.

You set the idle timing in the computer to say 10 degrees, start the car, then use your timing light and adjust the "magnet position" window (in the programming) till your strobe is reading 10 degrees.
Once you have that set your ready to set your timing (RPM IGN) curve.

This is the SDS F3 crank trigger manual hope it helps.
