V3 EDIS-x installation, set up, etc.

Nice work Paul!

 

I'm assuming that this rail is for O-ring injectors. Nice sturday looking mounts.

..........' date=' I'm just waiting for the Chrysler coil pack to come in at this point. I will also need to get the 4 pin connector.

 

Anyway, that's it for now.[/quote']

 

 

Pete,

Yes I am using C-4 Corvette injectors, O-rings top and bottom.

Did you order a Chrysler coil pack already? There are several more in our wrecking yard if you don’t mind going “used”. I’ll be going there on Friday to look at some “dual” style throttle valve for IR intakes. I could pick up a coil and connector for you as well and just package in with the valve cover if you like and I could even label the control wires as to which one controls which coil for you.

I think the coil packs are $25. Any how, let me know…

I machined the pulley, and made a sensor bracket this weekend. I made the VR sensor braket from some thin wall steel tubing, and 1/8" plate steel. It came out OK. It is not pretty, but it should be strong enough. I may make another bracket while I've got the motor out.

 

 

 

I machined the entire outer pully off. Once I time the trigger wheel, I will have someone that is good at welding weld it to the damper.

Nice work Pete. Definitely built very sturdy. Keep us posted...

so if all is installed correctly the edis will controll the ignion and there will be no need to upgrade to megasquirt or would it be best to first tackle the megasqirt? Really interestead in doing this this summer but need a few variables first as i am a novice at best when it comes to wrenching by the way great work so far mr. Ruschman

Clayborne,

Well, the EDIS will spark the spark plugs al by itself, but the timing will be fixed at 10 degrees advanced. That is fine for starting and idling ONLY! And engine needs more advance as RPMs rise, up to around 3000 RPM or so. Typically between 36 and I’ve seen as much as 42 on some engines. EDIS will allow the user to have pretty much any timing curve they can conjure up, (better to match it to he what that particular engine needs), and as such, you either need Mega Squirt or Mega Jolt Lite Jr (stand alone EDIS controller only), to tell EDIS how much more advance you need, and when.

In short, you will be able start up your engine on just EDIS, but if you want to drive the car around, you will need Mega Squirt or MegaJolt Lite Jr to control the EDIS system.

 

Hope this helps…

Braap,

I appreciate it and as i want the car to do more than idle I guess i will probably be investing in an MsNs this summer and hopefull I will be able to tackle the installation of this. Also you stated in a previous post that you would be doing this conversion on a 79 280zx with a/c this i what i will be running i have no power steering so i was going to put the edis wheel on the third pulley that would ordinarily drive that, but as far as the optical sensor i have no idea where im going to mount that so when you get around to that project i would appreciate some post of pics on that. Also whold it be ok to personal message you if i have any further questions?

[BRAAP]

Clayborne,

Glad we could help. You are welcome to PM or post publicly here if you feel that your questions might be something that would help others as well. In posting publicly here on the forum, you also get benefit of others chiming in with their ideas, possibly covering another angle that I or someone else didn’t think of.

You can think of this forum as a HUGE “International High Performance Z car think tank”…. By combining the little bits of different ideas, concepts, and theories that others have speculated over and actually tried over the years, from guys all over the globe, helps shorten the learning curve for those just getting started, and also helps keep the old schoolers on top of what’s “hot” and what’s “not” in the world of Extreme Z cars…

 

There was the Stone age, the Bronze age, the Industrial age, welcome to the Communications, or, Information age….

 

Isn’t the Internet wonderful?!?!!?

[clayborne]

i have to say that by far this is the best forum of its kind. I have asked many questions and as of yet nobody has called me a retard lol. My questions have almost always been met with adequate explanations and freindly advice. (although in the case of your answer and several others answers ive received from previous post it wasnt neccessarly the answer i wanted to hear.) But you people have kept me from doing a lot of stupid things by telling me answers i didnt want to hear. And outside of people flaming the non searchers i have seen no one be outwardly rude or distatefull to other members. Anyway just though id give this insight into my hybrid z experiance and thank you and each and every one of you that has replied to my posts. ps., Braap the personal message is a good option for me from time to time because there are some questions i feel stupid asking in the public forum becuase of my level of inexperiance, thus receiving an answer and maybe some day when i get a helpful knowlledge base going give some valuable answers of my own in the forums

You could actually use the EDIS setup and a MS to control just timing, but while you at it, you might as well do fuel control too. The precise control of both fuel and ignition will always get you the most out of your setup.

 

Update: My motor is getting close to going back in the car. I've got the supercharger mounted (I'll post pics soon), so any day now I should be getting it back in the car and fired up.

NICE.

Pete

Very very nice. Looking forward to seeing more posts when you get it up and running. That valve cover came out pretty nice as well.

So I finally got my trigger wheel all set up for the SC L28 EDIS project. I ended up using a 280Z pulley. I machined off the outer pulley, so the trigger wheel could be mounted to the SC pulley. The trigger wheel was made by a fellow Z nut on his automated plasma cutter. It is a 36-1 wheel with a custom diameter so it clears the SC pulley. Once everything was mounted, I put the whole assembly in the lathe to get all the trigger wheel teeth to run true to the 280Z damper.

 

For those poeple that want to go EDIS, but don't want to loose the outer pully, you can use a 280ZX damper. The 280ZX damper has a bolt on third pulley. The trigger wheel can be mounted in place of that third outer pulley with six 8mm bolts. I used the 280Z pulley because the SC pulley was designed for it. I would have had to make major modifications to the SC pulley to use the 280ZX damper.

 

I will hopefully get it started on the EDIS system this week. Right now it is running with a 280Z distributor.

Is this what you mean about using the 6 8mm bolts on the ZX pulley?

[BRAAP]

Very nice Pete. Looking forward to when it get it up and running on EDIS…

[z-ya]

Is this what you mean about using the 6 8mm bolts on the ZX pulley?

 

Exactly.

OK, got it running today on EDIS. Only encountered one problem, the way they label the coil outputs on the module is not correct for the L6. I ASSumed, that coil output A would go to 1st and opposed, B would go to 2nd and opposed, and C would go to 3rd and opposed. NOT! Hear is the wiring diagram:

 

 

They should be connected like this:

 

Coil output A (pin 10) => 1st and opposed

Coil output B (pin 12) => 3rd and opposed

Coil output C (pin 11) => 2nd and opposed

 

Everything else checked out OK on the EDIS MS FAQ.

 

Happy EDIS'n!

On the bottom of the spread sheet is mention of Ron’s voltage test comparing an Escort VR sensor to the 4.0 V-6 Explorer VR sensor on a spinning Escort 36-1 wheel at varying RPMs. The Explorer 36-1 wheel this sensor came from measures approx 3.7†or thereabouts. It appears that we just may have to acquire an Explorer 36-1 for more testing.

 

 

 

 

 

 

Is there a benifit to the higher voltage of using the Explorer VR sensor? I've read that the EDIS has an rpm limit. With EDIS4 higher than the 8, and 6 in the middle. Did you test max rpms? Do you think the Explorer VR would give a higher rpm or is it the module that limits it?

[z-ya]

I don't think there is an advantage inrunning a hotter sensor to increasing the RPM limit. I suspect that the RPM limit is not in the interface between the sensor and module, but in the speed that the coil drivers operate. As long as the input trigger crosses the threshold voltage to trigger the module, that is all that matters. Going beyond that threshold will not effect the RPM limit. A higer output sensor will alow you to run a longer cable from the sensor to the module, that's about it.

[Clifton]

Cool, thanks.
