Good evening
Is anyone using the Clewett Engineering crank fire set up?

Spendy... I think there are cheaper solutions... Anr't there? McMark?
Not the same Mark but....
I'm assuming this is for a /6.
Clewett Engineering crank fire set up is I believe Electromotive with their crankfire kit, it works good but is a bit spendy. The older units uses little dials on the unit to set advance and rev limit, I don't know if the newer models are now laptop program or not.
You sometimes see used units on the bird board.
MegaJolt Jr. does programmable EDIS crankfire or you can run megasquirt crankfire in ignition only.
Running the MS would also give you the future option of programmable FI. both are laptop programmable.
You would have to fab your own missing tooth wheel and trigger mount (not overly hard) or you can buy the Clewett pulley separate.
There is also MSD AL6-2 programmable ignition where you lock out the dizzy advance, but some have said the 2.0-2.7 dizzy cap is too small and causes phasing issues. You update the programme via USB flash drive.
I should add running megasquirt crankfire gives you more ignition options, MSD through the dizzy, coil on plug, Ford EDIS (IIRC), etc.
I've been looking into a trigger setup for sixes, but don't have anything yet.
Pretty sure joe at series 9 used one on a build
Personally it looks over engineered because they didn't think it through
Hangs a shaft off the front of the fan and has the trigger wheel in front of the housing
Mac marks setup is much much nicer and I used a different solution on mine that ill try get some photos of when I get home tonight

The kit in the link is for a 4cyl
I like their computer etc but on a four you get a much better result putting the wheel behind the fan or use a cam angle sensor
I agree that the fan mounted pick up is expensive and cumbersome. I like McMarks approach with the wheel mounted behind the fan. The magnetic sensor that they use is larger (longer) that the one that McMark used so packaging behind the fan shroud may be challenging.
There are two controllers XDI & XDI-2. The XDI-2 allows for the laptop

I have used it in the Past on 2 Cars in Twin-Plug applications & it worked well. I used early versions (Dials not computer adjustments).
My application is a 4, I was under the impression that MCMarks will only work with FI. I'm running carbs.

I've had the Clewitt setup on my conversion -6 for many years, and have been very happy with it. It is the older HPV-1 system that uses the dials.
While I'm sure that newer computerized systems are more flexible, the Clewitt system is reliable and beautifully made. The only problem is that it's very difficult to space the sensor if the engine is in the car. Luckily, I only had one sensor go bad in all these years, so it's not been that bad of a problem.
BTW the reason the /6 carb guys run a Clewett or megajolt jr is for dual plug (repro RSR dizzy starting at <$1900, plus the MSD and 2 coils) or a recurved stock dizzy is <$600, plus the MSD box and coil.
Those high prices makes the Clewett or megajolt jr solutions very attractive.
