Holla if you are running a FAST system...
Me...
FAST bank to bank system
Cartek crank box
Not yet running but all wired up
To me If I were going to a FAST system on my LS1 car (Have a Sequential FAST on my LT1), I wouldn't do it any other way, Crank Trigger, a Correct Cam Sync, and you can run a completely correct SEFI system w/ eDist.
Correct me if I'm wrong but doesn't Cartek's Box only allow you to utilize the fueling segment of the FAST system? Something I thought I saw on this board.
Running the above combination though it may be more expensive, would be a much better standalone option.

The Cartk box in fact just allows one to control fueling, so right now I am not running an EDist box and I am controlling the timing thru LS1 Edit.
I'd like to get rid of the factory harness and pcm but I'd rather have someone make a second gen Cartek box that phased the cam and crank sensors so I can do that... Dave??? Julio????

I have a Sequential FAST w/ ICC on my LT1 car.
You just confirmed what I heard. That being the case, hands down, I would use a crank trigger, and w/ a Cam Sensor (may need to look into weather the OEM Cam Sync will work, Anyone?), and the eDist box you can get around the Bandaid of having to use seperate ECUs to control the tuning. To me it would never be right until you have everything consolidated into the FAST system.
Getting rid of the OEM PCM/Harness is VERY nice as mine is that way in the 97, the only draw back, is now you're adding the cost of all new Guages also. I admit I haven't tackled this on the LS1 car, but most of its common sense. If you went w/ the complete setup I listed above, you could still use the PCM, and keep most of your guages, possibly just losing the tach (though I'm sure you have an aftermarket unit for that anyways....
I saw your post on Turbobuick.com, did you ever get that sorted out?
I'd for sure like to remove the factory system and adding some gauges does not bother me.
I also agree that an external crank trigger would be the way to go with an LS1/FAST. It's nice to be able to control timing vs rpm vs boost rather than just timing vs rpm.
Pretty Simple Setup for me really. Haven't figured out why more people haven't gone this route on the LT1 cars... Even for a B2B system, it completely gets rid of the Opti.
Chris' car is so close to being able to do this same thing Since he already has the small Diameter Dist. behind the Intake, and he could have saved himself the trouble of using the opti after modifying it. Just by adding the Crank Trigger, and switching the FAST box to IPU.
I'd rather have an electronic solution than a mechanical solution.
