EDIS Ignition swap (EDIS-8) 2 Attachment(s) I decided to to do a DIS swap on my Firebird. The things that compelled me to do so were: 1) I realized my coil might not be sufficient at upper RPM 2) My dizzy kept coming loose for some reason and retarding timing 3) It's cool. I went with an EDIS-8 ignition, which is stock on like 90-97 Ford V8. The EDIS-8 module only requires two wires for ECM control. 'PIP' and 'SAW'. PIP is a 12 volt signal sent by the EDIS module to the ECM to reference spark. The signal is +12 when the coil is actually firing. The ECM uses this to reference RPM. SAW is a 5 volt signal sent by the ECM to the EDIS module to tell it how much to advance or retard ignition. If either wire is broken, the EDIS module will continue providing spark at 10* BTDC. EDIS uses a crankshaft trigger, which is a VR sensor and a 36-1 tooth wheel. (Pictures attached). EDIS is a 'wasted spark' system, meaning it fires two cylinders at a time that are 360 degrees out. The EDIS-8 module, coils, VR sensor, toothed wheel, and plug wires can be had for under $200. That's cheaper than an ignition box. The nicer SBC wheel kit is a bit more money, but is ZERO fabrication. The universal wheel is $40 and you need to make a bracket. The nicer wheel kit is $180. I have a drawing file for the 'nice wheel', and have spoken with ACP waterjet in Massachusetts. The minimum they will do is a lot of 2 wheels for $160. I decided to just buy the wheel and bracket kit. I'm probably going to use an old distributor or something to drive the oil pump, since a oil pump driver for this purpose is over $100. I'm using a Megasquirt ECM, but I imagine this is possible with a stock ECM as well. The Delco hackers might be able to chime in on that. -- Joe |

Re: EDIS Ignition swap (EDIS-8) I'm in if it can be controlled with EBL. Where did you get the parts & reluctor. I've seen one that sandwiches between the HB and pulley, is that how yours installs? It appears to have slots for phasing? And 360* out describes it perfectly since a cycle is 720* the two firing are TDC power and exhaust. |

DIYautotune also sells wheels, but the wheel this kid makes is hub centric with the factory balancer, and allows phasing as you noted. (although that should really all be done with the sensor bracket). It sandwiches between the balancer and the pulley. Takes about about 1/8". I don't think I'll have a problem, because I was running a 1/8" pulley spacer anyway to keep the belts aligned. If I needed to I'd just kiss the balancer with the lathe.

They probably hang out at turbo forums or yellowbullet. -- Joe |
Re: EDIS Ignition swap (EDIS-8) Yeah I was just having fun. There's a lot of very intelligent members here. It raises the level of us old gear heads. |
Re: EDIS Ignition swap (EDIS-8) I don't see any problem with wasted spark. It would be timed before the intake starts to open much unless you have a very wild cam or retarded spark. It certainly satisfies the single coil dwell issue. |

Re: EDIS Ignition swap (EDIS-8) The northstar does use a cam sensor, I believe you can get a 730 to work with a 24x reluctor and vortec timing cover. http://lukeskaff.com/?page_id=380 Maybe Rbob will make a schematic if it's possible. |

The vortec timing cover is a no-go for guys like me with 400 blocks and retrofit roller cams. I'm using a special timing cover with a cam button. If I was doing sequential fuel injection I'd probably be interested in the cam sensor route, but I only have four injector drivers so I can't do sequential. Looked at Luke's page, so in theory that system is almost plug and play with a GM ECM, you just have a little more complexity with two crank triggers. -- Joe |
Re: EDIS Ignition swap (EDIS-8) Yeah I noticed on Luke's page the project status is "discontinued". I wonder if he didn't finish it and why. The GM route does seem to be a bit more complicated. But if DIS or EDIS can be controlled with the GM ecm we're set. Another thought, and one I believe I saw on Dynamic EFI basically takes a "wasted spark" system but run it through 6 CNP coils. Presumably firing two at a time. I think that'd be ideal. One of the features I like is not having long wires running across the motor. Both DIS and EDIS still have a common location wire connection albeit 2x4 or 4x2 coils. |

On my application since I'm running LT1 manifolds backwards (turbocharger) I need to run the coil packs mounted on the firewall and the wires run under the manifolds.

Re: EDIS Ignition swap (EDIS-8) Good info and good job of coming up with that "dual EDIS" module schematic. I understand the mechanical and electrical but wish I were more computer literate. I can see how it all hooks up, the EDIS Pip and Saw channels and the ECM outputs, but I don't know how to make them communicate. That's why I'm interested in your thread and what others are doing. Megasquirt and other aftermarket ECM seem to provide a lot of information or have more universal interfaces but GM didn't make it easy for us. Heck I'm almost surprised that someone figured out how to modify it at all. Your comment about "making it cool" sorta goes to the heart of it. I could probably buy a MSD box and have a good ignition. But hot-rodding is really about doing it a little different or combining systems that were never meant to work together, combining the best of both worlds. Heck if I just wanted a 400+HP LS Camaro I could go buy it this afternoon (well maybe tomorrow since N Alabama is shut down because of 1/4" of sleet lol) but there's just something about a 26 year old IROC lumpity-lumping into the gas station. Yea it rides a little rough and isn't as tight as it used to be but it "fits" me & reflects my personality. I digress to say the EDIS mod is interesting for practical and other intangible reasons. |

These modules are pretty cheap both from junkyards an ebay. Guys could run 2-wire CNP coils mounted on their valve covers. It would also make running an LSx motor with a '165, '730, or EBL pretty easy which I think would open up a larger market for those ECM users. Before I went with the MS, one of the things that prevented me from diving into the LSx stuff was I had no interest in the electronics. It would be nice to be able to change engines if your SBC explodes and go with a 6.0 or something without having to change any of the electronics / management. Just my opinion. -- Joe |

Re: EDIS Ignition swap (EDIS-8) I have been running EDIS on my twin turbo setup for a few years now. I use Accel DFI to control it, but it works great. The only thing I don't like about it is that you have to run another ignition controller for rev limiting and 2-steps. The EDIS signal can't be interrupted and the rev limiting needs to be done post EDIS module (if that makes sense) Otherwise its a solid setup and has that cool factor when you pop the hood... if a twin turbo small block wasn't enough. |
Re: EDIS Ignition swap (EDIS-8) Anesthes, Is that slave Buick adapter for harness connector that plugs into stock ignition module? Why did I think that was a 14 pin? |
Re: EDIS Ignition swap (EDIS-8) Oops. I was thinking the slave was a female version of the harness connector? Is there such a thing to take the place of the ignition module? |

Yeah if you interrupt the EDIS it will simply continue at the same advance setting until the timeout period, in which case it will then do 10* BTDC. I've seen a few different boxes that work with EDIS to provide spark RPM limit. Have you used any? Otherwise, one can just do a fuel cut like the OEM stuff I guess. -- Joe |
Re: EDIS Ignition swap (EDIS-8) Youre right, it will kick it to 10 degrees until the module is powered down. I run an DIS ignition box "post" EDIS module that modifies the signal for 2-step and such just to keep the EDIS module happy. The module never knows its on the rev limiter it just keeps triggering as usual. Its an older Accel DIS ignition box, but seems to work pretty well. If I really needed just a top end rev limiter I could just kill the fuel, but I really wanted the 2-step for boost building. |

Re: EDIS Ignition swap (EDIS-8) 1 Attachment(s) Here's what I did with mine |
Re: EDIS Ignition swap (EDIS-8) The EDIS is not compatible with a Delco ECM, the signals are too different. There has been some speculation about modifying the code to modify the signals appropriatly, but so far that's all it is, speculation. No one one has done it so far since the GM DIS is readily available and easy to adapt. The Northstar coil pack does not need the cam sensor to operate. It needs 2 of the 3 sensors to operate correctly. Most people that swap these ignition systems into their vehicles (actually all I've seen so far) use the two crank sensors. The Northstar trigger wheel is a special trigger wheel and based on the spacing of the notches and the timing between the two sensors the ignition modules knows where in the firing cycle the engine is. There was an extensive thread in the DIY PROM forum from someone who used the Northstar system in their SBC. I don't recall the name of the poster, and he did have some issues at first, but it was tune related finding the correct offsets and min max timing values to get it to work correctly. |

Also, the cost of the northstar stuff seemed a little bit more expensive, and information on using it was sparse. (luke's article being the most complete yet abandoned). I'm surprised a factory ECM can't drive an EDIS, especially with the man himself said over 10 years ago it would be simple. I think maybe it's just more lack of demand. I suspect that guys wanting to do DIS with Delco electronics are probably jumping to LSx PCM's and skipping the 80's stuff all together. -- Joe |

If GM would have instead used a system more like the LT5, that uses a much simpler crank trigger and overall system, I think there would be more support for this in the V8 market. The 4cyl and 6 cyl system both use the same trigger wheel, which is similar to the LT5 trigger wheel. Then GM decided to go way out into left field with the Northstar trigger wheel, while it's amazing how it works and I can see how timing can be improved greatly over the old system, it was only used on that one engine (that I know of). I have Northstar coil pack on my shelf that is slated to go on one of two projects, if I get a second system I might put one on each. |

Well, since we're in agreement that the Northstar stuff is somewhat complex and doesn't have much support outside of it's original application, I think I'll maintain my position on using EDIS at this point. I'd really love to see one of the Delco hacker's get it working on a stock ECM. Again, I think it would even make things like LSx swaps easier in thirdgens and C4's since people would be able to keep the electronics they are used to tuning. Most members don't mind swapping parts, but fabricating reluctor wheels and sensors isn't the same as welding up an exhaust. Back to EDIS and Delco, the PIP wire tells the ECM engine speed. This is 12v square wave. This is quite simple, +12 while the coil is firing, then 0 volts. The duration of time is directly related to engine speed. The SAW signal is just a pulsewidth, with the duration of the pulse directly related to the amount of commanded degrees. When the ECM sees PIP go to zero volts, it energizes SAW for xxx usec based on desired advance. Surely the Delco ecm has an input that can not only read voltage but do so in a timer loop, and surely it also has an output pin that can be time pulsed. The problem as I see it is finding someone who can code it up. -- Joe |
Re: EDIS Ignition swap (EDIS-8) 2 Attachment(s) Here is what the crank reluctor and vr sensor looks like on my SBC. Gap set to .050". VR sensor 5 teeth ahead of blank tooth. (4 teeth in between).

Re: EDIS Ignition swap (EDIS-8) 1 Attachment(s) Welded up a bracket to hold the coils. I took two coil brackets from a late 90s crown vic, cut 'em up and welded them together. This will mount the coils to the firewall in the area where the distributor would be. I was doing some more reading on EDIS and found this functionality: The EDIS module has the capability of performing recurring spark, more commonly referred to as Multiple Spark Discharge. The latter is usually associated with CD ignition boxes. This feature was introduced with the 1990 1.9L Escort/Tracer engine. The ECU enables the MSD below 1800RPM on these engines. To signal to the EDIS module that MSD is desired, the SAW is lengthened by 2048us on 4/6/8 cylinder units, and 1024us on 10 cylinder units. The EDIS module can achieve up to 3 sparks per cylinder event using this feature. -- Joe |

There are 4 different Mask IDs. $8E for 90, $AF for 91, $D0 for 92, and $F0 for 93-95. Each of these has an "A" revision GM did for some performance and driveability enhancements. No VTEC altho a 2Gen motor did have a version of VTEC designed for it. Someone at Lingenfelter actually has built one of these and installed it into a C4 ZR-1. Supposed to be 475hp out of a 5.7L NA motor. Would have been glorious. |
Re: EDIS Ignition swap (EDIS-8) WOW anesthes what a great idea using the ford coils, wish i had come across this sooner. Im building an LT1 to go back in the place of a tune port motor i put in my caprice. Im using the Northstar setup. there is a lot on Thirdgen about the northstar stuff just search "Do away with the dizzy". like to know how the EDIS goes for you, i might use the it in my truck. jonarotz i like the setup very clean, seen most people mount it on the valve cover. me i have lots of room so i made a bracket that mounts the northstar system where the distributor was. good luck on this hope it works well. https://cimg1.ibsrv.net/gimg/www.thi...6209313ff1.jpg |
Re: EDIS Ignition swap (EDIS-8) 1 Attachment(s) That fit nice! I wanted to put the coils behind the intake but with the stealthram they don't quite fit. Here is a test fit of the coil bracket I made from a couple of crown vic brackets. Ordered a 8mm plug wire set no boots on the plug side, so I can cut to fit and crimp 90* boots on. So the plug wire arrangement should basically be like: 1 8 4 3 6 5 7 2 -- Joe |

Re: EDIS Ignition swap (EDIS-8) You should probably start a new post. Using Ford EDIS electronics is nothing like Northstar or GM DIS. I think Street Lethal has a v8 DIS setup working. I chose EDIS because the crank wheel is easily obtainable (no fabrication), and it just 'works' with most aftermarket computers. -- Joe |
Re: EDIS Ignition swap (EDIS-8) 1 Attachment(s) I actually have not been able to touch the car in a few months. Had to renovate and sell a house, busy with work, etc. I did spend a couple hours this evening finishing up the wiring. I've got some welding to do and then it should move again. -- Joe |

I was even carbed at first, then went efi Attachment 322904 then I went to the efi connection 24x stuff Attachment 322905 then I eventually just went ls1 http://i91.photobucket.com/albums/k2...h/DSC_0356.jpg |
Re: EDIS Ignition swap (EDIS-8) over on $59 there was a thread about what believe was this box and getting it to work with the gm ecm, and I believe it was turbo dig that did most of the code work and said it's probably possible, but nothing he wanted to get into.

And im running an lt1 with no distributo.https://www.thirdgen.org/forums/diy-...way-dizzy.html is there a build thread? I'd like to check it out. I still have 2 wheels cut to slide over the crank pulley and tack weld on my tpi car but new job killed my car tuning and building for like 5 years lol the do away with dizzy was just a fun project. I still remember when someone posted up saying, hey you can't use a dial back timing light for wasted speak. talk about a relief yet wanna throw the light across the yard lol. |
Re: EDIS Ignition swap (EDIS-8) Hi Joe Check this out not EDIS but looks promising. https://pcmhacking.net/forums/viewtopic.php?f=11&t=2913 With a 36-1 trigger wheel you can run 8 ls2 coils. |
