The new Holley EFI pricing sheets have decreased the cost of Holley Dual Sync Distributors for SBC and BBC's by almost $100.

Apparently, they outsourced the manufacturing to MSD and ended up with an almost $100 price reduction.


For anyone who bought a Holley EFI for their SBC or BBC but didn't implement the ignition control features, a $100 price break might be enticing.

Thanks for the info I am getting ready to purchase for another project.

Lets keep in mind that Holley owns MSD.

Update:

Holley's now announced the "HyperSpark EFI Distributor" for SBCs and BBCs; it's plug-and play with the Holley Sniper. It doesn't start shipping until later this summer, but it's only $249, (another $100 cheaper than the option I posted a week or so ago) so EFI-controlled spark is now cheaper than an old-school distributor....

That's kinda nuts and kinda awesome at the same time.

If this had been out when I was buying all my stuff I probably would've just gone with this vs. a Vortec single sync cam sensor and CNP LS coils....

It's even got a cool clear cap for easy installation and positioning and it then locks itself in place.



If only they made a drop-in, in-tank fuel pump and hanger for the various C3s tanks....

Now if Holley would just adopt CAN Bus and allow Bluetooth tablets to act as the touch screen... (I can dream...)

What?
No tach drive??

Don't forget that you'll still need a coil. It's pretty cool that this setup includes a coil driver module. I didn't like having to add an ignition box in my setup, but I hid it pretty well.

Speaking of CAN bus, my system does do that and I tapped into it a while back.

A project I ultimately gave up on, but I did spend some time deciphering the CAN data in my setup:


Having CAN alone doesn't actually mean much. CAN just describes how data is sent across a network. You'd need to know how they encapsulate data in a CAN message and then write a decoder for it. What you see above is a USB2CAN module talking through a CAN socket connection to a Java app I wrote that deciphers the CAN frames and converts them to some data (TPS, RPM and temps). I didn't get around to deciphering all the data on the wire. The latency sucks because the machine I used at the time was underpowered and there weren't any drivers available to offload rendering to the GPU for that particular piece of hardware. I did a RasPi setup later on, but that came with its own suite of problems, but the display throughput was decidedly better.

Back to your comment on CAN - are you thinking of OBD2 bluetooth dongles? OBD2 defines a series of common PIDs that all cars have to provide for emissions diagnostics - this is what would enable you to read stuff via bluetooth in a modern car.

For as commonplace as stepper motor tachs are these days, I’m still surprised that no one has come up with a retro-fit kit for our cars.

For now, I’m still using my tach drive dist to provide the 1x cam signal for my ignition (still using single coil) and to drive the mechanical tach.

Where can this be found?

jim2527

not being a smart *** here but google 'mechanical tach drive converter box' and you'll see a bunch of choices. Personally, I'd swap out the tach.

Am I missing something? Buy 75-77 electric tach from junkyard/ebay. Add early faceplate with desired redline. Replace tach board if needed. The whole thing was less than $200.

NewbVetteGuy

Wait... What?!? Will that actually work? I don't understand how the 75s-77s had electronic tachs and then they converted later to the spinning analog cable things again for 79?? -That makes no sense.

If this is a real option, I might just sell my Dakota Digital Box.

To answer the previous guy's question: I bought the Dakota Digital ECD-100. I found it for $200 which is still a rip-off, IMO, but if Zwede's idea will work, it seems way better...

All tachs were electric from 1975 and up. Maybe you're thinking of the cruise control transducer that's hooked to the speedo cable? What year is your car?

Edit: Reason I went with 75-77 tach for my '71 is these fit right into the cluster with no mods. Later tachs had different housing on the back.
