EDIS Test bench, now operational…

[78Spit1500Fed]

Thought I'd update... I was originally talking about a 72 toothed cam trigger wheel. With the future looking pretty booked I decided to take the "easy way out", for now at least. I took the 510 damper and, becuase I'm not using the rear V-belt, machined 36-1 teeth in the rear shoulder. Pretty painless and, due to our testing, I'm quite confident it will function well.

To be completely honest, you'll probably be happier with this setup. You're now taking all the clearances between the crankshaft and the distributor out of the equasion.

Now you can see true crank position, not crank position derived from belts and gears and whatnot.

Nice, clean install! That sure looks a LOT better than the old dizzy/wire setup. I'm jealous.
My car has brake lines at the same spot on the firewall so I can't mount it there, dammnit!!
 
The change was quite noticeable when I put the edis on my car also. Smoother, better gas milage, and a drop in temperature. Considering wasted spark directly from v3 pcb to clean things up a bit more........
 
Where did you get those clips for the leads?

"Where did you get those clips for the leads?"


Thanks Guy's.

Daryl, They are MSD. I don't have the part number handy... sorry. I picked 'em up at Baxters. I believe Summit sells them as well. Let me know if you have trouble finding them and I'll dig up a part number.

Thanks Ron,
Couple of decent performance shops here that should have them. If not I'll ask for a part #.

BRAAPZ.....just wondered what ended up being the best distance from sensor to wheel clearance?
Was it .045" I'm about to start work on mounting etc.

[BRAAPZ]

As for “best”, or, “ideal” clearance, we don’t have a definitive answer as of yet. We still need that “O” scope. I do feel confident in saying that if you keep your “matched” VR sensor within .020” and .060” to its matched 36-1 wheel, you will have no issues that would result from the VR to 36-1 wheel clearance. What I mean by “matched” is, the VR and 36-1 from the same “type” of donor vehicle, i.e. Ford Escort VR and wheel, or Ford Explorer VR and Wheel, etc… Also, from our testing, it appears that the EDIS-4 is the least sensitive to pickup clearances, angles, teeth depth and thicknesses, etc, as compared the EDIS-8, and my assumption is that the EDIS-6 falls somewhere in between…

Hope this helps.

Hi Paul, I sent you a PM regarding testing...thanks.

[Karch]

Hi Paul,

Any chance you were able to take a look at the wheel?

Thanks.

[BRAAPZ]

DOH!! Please don’t kill me. I PROMISE to have your custom wheel spun up on the Test bench and will post pictures of the Fluke “O” scope trace of it compared to the OE Escort trace by no later than Monday eve, Pacific time.
I deeply apologize for it taking so long to get to this. We are currently buried around here at the moment while getting back on track. We just shipped out a custom high profile cylinder head that we built recently for a “speedtv” project car and due to the TIGHT schedule for the taping on “speedtv” this month, all other projects were set aside here at Rusch Motorsports. We are just now getting back on track with business as usual and the EDIS test bench spin up of your custom 36-1 will happen this weekend.
In short, by Monday eve, I’ll post that info for you.

Again, we apologize for any inconvenience this may have caused.

Hey Paul, absolutely no problem. I am not even close to running anything, as I am buried myself with a new job, traveling for that job, meetings, family, etc, etc.

Seriously, you are doing me a favor by testing it, so don't put any additional stress on yourself...7PM Monday is fine (just kidding).

Thanks again for testing the wheel, and congrats on the SpeedTV project. By the way, what is it called and when does it air?

-Karch

[BRAAPZ]

Glad we could help out.

As for the SpeedTV project… Hmmm… well…. Uhh… at this time it is classified. I am not at liberty to divulge even what show it will aired on till after the taping, and then only some details can be released until it airs. I can tell you that that taping will happen later this month and airing will be approx 2 months after that and…. this project is also running “MS” as well….

[BRAAPZ]

We will be posting the trace tonight!

Finally…..

Thanks for being so patient.

[Karch]

...very much.

I'll be looking for it.

How did it work?

Also, I found another source for the wheels, but it is more expensive...more like $50/ea, if I buy 50 units.

Probably not worth going after at that price, unless some peoples want to get together and buy in bulk (even cheaper at 100+ units).

[BRAAPZ]

Finally, here are pictures of the trace.
The first picture is of Karch’s custom 36 tooth wheel underneath the Escort 36-1. The second picture is the trace from the OE Escort 36-1 using the Escort VR sensor, running .030” VR gap. The third picture is the trace from Karch’s custom 36 tooth wheel with the Escort VR running at .030” VR gap. Sorry, but during the tests, they were spun at different RPM’s. If time permits this week, I would like to run these wheels again at the same RPM to acquire a voltage reference.

That sounds expensive. We are able sell wheels retail for less than that
and we can economically make just 25 units at a time. We could have some
made up but shipping to the US isn't terribly cheap, but if someone wanted
to act as a middle man then we could put as many wheels as we could fit
in a package for about $50.

If I can be of any help drop me a line.

Do the EDIS sensors have any issues with these wheels from Karch? I just got a price back from Electromotive for their magnetic pickups....... $75USD each!

Hopefully I can find a source for EDIS VR's locally!!

[Karch]

Thank you very much, Paul.

Since I know very little about these, can you explain the differences in the patterns of the two? Can you anticipate any real world difference?

I left you a voicemail yesterday, but no problem as I know you are very, very busy.

Thanks again,

Karch

[BRAAPZ]

Let me first start out by saying I have very limited experience with the EDIS currently, and Karchs’s wheel is the first “non” Ford 36 tooth wheel we’ve actually captured a trace for, so I don’t really have much to compare to it to.
As for it working or not, Being as we were able to get EDIS-8 to fire up to 5600 RPM while spinning a single 4-1/2” diameter saw blade in-front of the VR, (pictured below), I don’t see any real world issues that would arise from the slight difference in the sine wave of Karchs wheel vs the OE. I’m sure Karchs wheel is WAY cleaner and WAY more consistent than some of the other home made wheels I’ve heard about that are running EDIS-X, (actually read on here somewhere that someone “hand filed” the 36-1 pattern into his Small Block Chevy damper pulley….)

At this stage, my only concern would be the voltage produced from any ole VR running on a larger diameter 36-1 wheel. It seems as though the EDIS engineers matched the OE 36-1 wheels and VR sensors on the various vehicles so that they produce similar voltages at those same RPMs (i.e. Ford Explorer, 4.0 V-6 uses a small diameter wheel and a sensitive VR vs the Escorts larger wheel and less sensitive VR). Also of note is the thicker the wheel, the more influence that has on the voltage produced. Does that have any relevance to EDIS? Good question, we don’t know. We do have a theory that there is probably a point at which the EDIS module will fry from excessive input voltage from the VR, and as such, our current thinking on this is to try and mimic the voltages produced at given RPMs to that of the OE setups. The OE systems work and work fine so I can’t see any reason to test fate.

Did you have a chance to run 2 of the SAW blades together to make 72 tooth and 2 missing teeth ? I'd like to know if the EDIS-4 could catch those...

That would fool the EDIS that it would run at 11200 RPM.

If the EDIS-4 would still run that would be amazing!

No we didn’t get the chance to run both saw blades together and most likely wont for at least 6-8 months. Sorry about that.
