Anyone running a trank trigger on their LT1? If so what type of trigger did you use and what type of stand alone setup are you using for control? I am building my new 383 currently and want to go with a crank trigger system and would like to get your feedback on how you like your setup.
Thank you very much,
RJ

a friend of mine that posts on here ran a crank trigger setup for a little bit because he couldn't chase down an ignition problem. i'm not sure what it was that he used, but i'll search for the thread or tell him to post up.
I am using a MSD 7" crank trigger and a MSD low profile crab style distributer. Using the FAST XFI as the management system with bank to bank (batch fire). Just purchased the stuff so I do not have any numbers yet.

are you still going to use the Opti to dist. the spark? i think batch fire only need's a crank signal to run where as Sequential would require a cam signal... So tony's probably just running the crank signal and using the dizzy to dist. spark

I've always been curious, for the guys who've run both batch and sequential injection, what are the pros and cons of each? I'm most interested in what people consider to be the "improvement", (if any), that sequential has over batch. And what are the limitations involved with using batch fire? I'm asking because I too plan on eventually ditching my Opti in favor of an aftermarket EFI setup, and wondering if the rather steep price difference between a "sequential capable" and a regular batch fire system is at all justified?

). Figured I'd build a custom billet cover for the opti, ditching the cap/rotor. If I go this route and it works good then I might get the new MSD Opti with the bigger bearing, better eye sensor and just run the billet cover on that with the LTCC setup. Always wanted to do the crab style dist setup, would love to know if you can pull the crab out with out dropping the engine.

You are correct in the part throttle and drivability aspects. Also sequential is better for individual cylinder tuning if needed. Both work great but sequential is a little better overall. Especially for a street car.

Stefan D.,
You stated you had your MSD distributor modified. I take it you had a cam sensor installed so you can run Sequential. If so, who modified it for you. i have a front mount MSD and would like to have a cam sensor installed.
BTW, another good reason to run sequential is when running large injectors to help with the idle quality. I have 160lbs. injectors on my 598 and want to run the sequential for that purpose. Other than that I'd run the batch since i't a drag car.
