Ross,
If we are to keep this objective, then we ought to use the same format for all brand, that is all I am saying. I would have found it objective if you had put extra cost, much as it has been done for SDS for Backup power.

Then the user can investigate to see how much and to what extend those capabilities exist, whether is programmability or the back up power.

To be fair though, there is some confusion about "programability". Some believe that the curve shift offered on the Pmag qualifies, but it's not the same as the SDS stuff. It's a grey area we need to work through as new products emerge.

That only addresses if the MAP sensor gets disconnected from it's source. That doesn't address what Michael was talking about, which is a failure of the MAP sensor and the eroneous data it will provide to the CPU.

I agree with you except that none of the other EIs are truly programmable as SDS, as Mike says below, so you'd need to qualify that in your chart.

My aim was a simple chart showing the basics of standard capabilities, costs and features, which can't go into great detail. I threw the floor open for someone to make a more detailed chart as was done before by the OP of this thread. The invitation is open.

For detailed comparisons, I'd suggest folks hit each EI manufacturer's website and see which features and price best suits their mission.

As for Lightspeed, you can connect a simple 10k potentiometer to the box to be able to shift the existing timing curve up or down or both (forgot which), and you can connect an output of the box to your EFIS to display the actual timing. No need to buy the (expensive) standalone indicator from Lightspeed.

While we're being fair, let's add Paisley's System 32, since he has now posted an installation manual.

The EDIS-based system too.

Is the System 32 actually flying, or is it still vaporware?

I just listed the popular, commercially available systems. There are others. Home made stuff is usually one-off unless Dan is going to offer EDIS kits? I've built fixed timing stuff 20 years ago with a couple Hall Effects and an HEI module for $50 but I won't be producing them for sale.

Anyone who wants to compile a bigger list and all features- go for it. I just responded to George's post for an update.

The system32 is NOT vaporware. I have the complete system, in hand. First star very soon...

Assuming apple-to-apples crank triggering, the only "homemade" components (cue the dire music: https://www.youtube.com/watch?v=B38ohaelNBQ ) for an EDIS based system are a toothed wheel and a pickup bracket.

EDIS box, Ford OEM - I've bought NOS units for $100. Used EDIS units are found everywhere, worldwide. It's a sealed brick.

Megajolt/E MK2 controller - AutoSport Labs - $199

Pickup, coil, plug wires, boots, plugs - generic auto parts

Plug bushings - multiple sources (including SDS)

It's an electronic ignition, not a nuclear weapon.
