That is one thing I learned early on, it might not be ready when I am/I think it should be. Still doesn't make it better, but it's not that bad. It's kind of like getting everyone to sing in the right pitch, it comes together.
I love/hate the anticipation.You're sounding dangerously close now...

Well, I turned on the ignition and triggered the Crane Fireball by touching a grounded wire to its input. There is very certainly spark at the coil. So, it’s looking like the FiTech may not be “seeing” the MSD Pro-Billet magnetic trigger. I can find very little help online about the pickup polarization, so, I tried reversing it. After all, it’s just a magnetic pickup. No change. I have the FiTech set to “VRCoil” and everything is wired rather nicely.
One clue, upon cranking, the FiTech RPM reads 0. That’s not exactly what I would expect. I’ll read up and sleep on it. I may get an oscilloscope after it tomorrow. Mess with me....grumble grumble.

I had to run my MSD pickup thru a GM HEI module on my ancient Holley Commander 950 Pro system. The ECM needed to see a square wave tach signal and the mag pickup makes a sine wave. The HEI module converts sine to square.
No idea if this is relevant to FiTech.

On my Sniper, I'm running an MSD Street Fire triggering a pertronix 1. I have the tachoutput from the MSD going to my Sniper. I believe fitech and Sniper are similar. Are you attempt to control timing right off the bat?
I had a similar thought, good call

I also had to use the Cap Adapt and adjustable rotor to rephase the rotor.
On the Holley the ECM needs to see the pickup signal about 10 degrees early so it has time to calculate the timing and then trigger the 6AL.
The distributor timing mechanism is locked out.

Yes, contrary to popular wisdom, I’m planning to run timing control from the “start.”
I thought about this last night and determined that I simply couldn’t be getting an ignition signal during cranking. So, I put the meter on it this morning. Lo and behold, ignition is low during cranking. I failed to jumper the little brown wire together with the little dark blue/trace wire to trigger my ignition signal relay. Duh! I knew about this. I just didn’t follow through.
I have a day job, so, after work I’ll make the change. I’m thinking about forgoing the original keyswitch all together and triggering the ignition relay via a separate, hidden keyswitch.
Having ignition hot during cranking will probably make things work more better.

Today I fixed the wiring so that the system sees 12 volts both during crank and at run position. I also pulled the distributor and primed the pump for sure.
Here’s how I primed it:
I pulled the distributor, taped up some killer blacksmith tongs, reached in and plucked out the drive gear, inserted a long 5/16” octal aluminum shaft, spun it with a drill motor going CCW. Got good pressure. Re-located the distributor, routed wires, gave it a spin.
It’s firing now. In fact, it’s hitting right at the desired 16* base setting. However, it’s not starting. It initially backfired out both ends. We’d flipped the key on and off a billion times or so. So, I expect that it may have flooded due to a billion priming shots. It’s happier when I barely hold the throttle open. So, I also think that it’s rich. I’ve turned down the priming shot duration (and, thus, priming shot volume). Tomorrow, I’ll begin to adjust the cranking fuel and maybe the cranking IAC and fuel/air ratio target.

If you think it's flooded, just hold it on the floor and crank it. It will clear itself and run.

Yep, I did that and it started to try a little harder. However, I think that it’s still rich. I’ll ease into the data analysis tomorrow. I think I’ll plan to update it tomorrow and then restart from scratch. Dylan must have bought this thing about a year ago.

I already have >2 hours of footage to edit into a <1 minute video. Being an armchair mechanic is fun.

The suspense is killing us!!
Really looking forward to hearing what a roller cammed FI stroker sounds like!!!

good lord on that lift at you trying to just stick the fuel hose directly into the chamber? lol

When checking for number one compression stroke yesterday, I put my finger in the plug hole and my loving wife key-bumped the starter. Expecting a gradual push of air, followed by a strong pop, I was made aware of just how much duration and overlap this thing had.
Bump - nothing

Bu..BAM! My finger shot out the hole in a very brief, but very stout, burst of air pressure. Then it was over as soon as it started.
This cam is rather radical.

I think it’s going to be a matter of gallons per (1/4th) mile.
