old box on 04 5.3 Hi all, I bought a SEFI8L0 new many years ago for a drag bike project and never used it. I would now like to use it on a twin turbo 5.3 truck engine in a rat rod I am building. Question is can this be done without buying the front drive distributor set up like FAST has told me? I know they are experts, but am hoping someone on here has done it. its the old grey box unit with wbo2 option. any ideas? thanks in advance.
Standard Features
Base Unit will drive up to 8 high or low impedance injectors in bank-to-bank fuel injection mode. This mode fires at most, 2 injectors per side at any one time and will reduce fuel pressure fluctuations over batch fire mode resulting in better fuel distribution to all cylinders. Each injector is controlled by its own peak/hold driver.
Base Unit has 16 x 17 spark and fuel matrices for ultra-control of the engine spark and fuel events.
Base unit is fully up gradable. Systems can be later updated for sequential fuel injection, closed loop - wide band O2 sensor fuel control and individual cylinder fuel and spark trim.
Waterproof enclosure allows for under-hood mounting.
EMI Hardened Design. This system was designed to be immune to the eloctromagnetic interference common to hi-energy ignition systems.
True Speed-Density algorithm greatly reduces calibration time and improves idle characteristics with big injectors.
Compatible with all crank triggers and ignition systems.
2 stage wet or dry flow nitrous control
Hi-speed communication from the ECU to host PC

I have never heard of this particular system before.
I googled it and it came up with FP Performance Electronics- SEFI8LO Engine Management System. I believe maybe they sold it at some point as when go to there home page, I can not find it on there. But this link still shows up as active for the product. http://force-efi.com/felpro.htm
It says it is "Compatible with all crank triggers and ignition systems"
According to a book called "How to Tune and Modify Your Ford 5.0 Liter Mustang" it looks like It was created by John Meaney and sold to fel pro performance division.
Any way, Being that it says its compatible with all crank triggers and ignition systems I don't see why it wouldn't work other than maybe you can not program a firing order into it. The Techs at FAST did not elaborate on why you needed the conversion?

they said i need to get a front drive distributor for it. really didn't want to go back in time with this if i didn't have to. dont get it. may have to buy another new unit again, never even had power to this one, cost 2k when i got it.
If you have the stock pcm from the 5.3 you would come out better just using it. The cost of the extra hardware will easily surpass the cost of HPtuners or EFIlive software, and a stock PCM and wiring should be super cheap from a junkyard if you don't already have them.
