Engine Distributor Delete!

OK so I did some more googling, and think I've convinced myself to do this at some point

Only question that remains is the mounting of the 36-1 trigger wheel. First off, is a 6 3/4" trigger wheel the desired size? Secondly, is it simply sandwiched between the balancer and the crankshaft pulley? Doesn't that throw belt alignment off?

It seems if it were to get mounted to the backside of the harmonic balancer, it would offer a cleaner install if using an explorer VR sensor, which looks like a direct bolt on replacement for the stock timing pointer (it even has a timing pointed on the crank pos sensor as well)?

Everything else looks pretty straightforward and I have parts in the mail (scored a NOS edis8 unit for $30 shipped), as well as a junkyard trip setup to grab some wiring and any other parts I can find. Only question that remains is mounting of a 36-1 trigger wheel. Beyond that, I have the means to fab up a crank position sensor mount fairly easily.

What is the explorer cam sensor gear made out of? Compatible material for the Mustang camshaft?

I believe you will mount it to the backside of the balancer. The gear is correct for a roller cam

Looks like it won't work with a virgin A9L. I know you guys are all running aftermarket ecus, but I'm not quite there yet even though I would like an MS3.

With an A9L, the Explorer cam sensor does get wired into pin 24. It's used to time the injectors pulses. But, unless you go into the programming and change a few scalars to activate the EDIS and have it look for the cam sensor input, you will forever be locked at 10* of timing with no computer advance.

From what I can see, a twEECer or misted or similar is needed to change some A9L Parameters. What's the cheapest setup that will allow me to do this? I feel any significant expense would better be served investing in an MS instead.

Still a cool project. I've gathered the parts and figure when I pull my motor for the HCI install, I can mount the 36-1 wheel and crank VR and have that ready go down the road.

The ms3 will darn near launch the space shuttle. What are you looking for functionality wise? Maybe I can help.

Not sure yet. As many know, my car sat for pretty much 10 years. The last year or so I've finally begun to play with it and finally digging into the power plant.

As an engineer, I just can't leave alone. I have to do something unique more or less to challenge myself. Just quite haven't decided on what yet.

Right now, I wish there was a way to change 4-5 scalars in the A9L code without spending $500+ to do so.

FYI, for the sake of keeping info for search purposes..

This pertains to wiring with the A9L.

Explorer cam sensor wires to pin 24. There are two different cam sensors, 2-wire and 1999-later got a 3-wire. 3-wire is Hall effect and 2-wire is VR like the crank sensor. Unsure which is most ideal for this scenario. MS doesn't need cam sensor

As for what scalars to change in the A9L logic, taken from http://www.efidynotuning.com/ignition.htm

For those whom are swapping to EDIS from either DIS or TFI ignitions the following tune changes will need to be made:

PID Description New Value Old Value Comments
HP_HIDRES EDIS Module Present 1 0 1=EDIS Module Present
HP_CID CID Present 1 0 Cam Sensor Present
HP_CIDSEL CID Sensor Type 1 0 Determines if hall effect or variable reluctance cam sensor is present
DPL_DHP Dual Plug Ignition 0 0 Dermines if a dual plug ignition setup is present
IGN_TYPE Ignition Type 4 0= TFI, 1= TFI w/ CCD (94-95), 2=Low Data Rate Distributorless Dual Plug, 3= LDRD Single Plug, 4=High Data Rate (EDIS)
MHPFD Signature PIP Duty Cycle Offset Constant 0.990 .20

Note: IGN_TYPE is not available in older ecu's such as the GUFB strategy.
At this time, it is only known that CZAJL, GUFB, CCAQA, CCAQE, and the CZAW0 strategy EEC-IV's support EDIS ignitions. This excludes the crown victoria and lincoln towncars that use unsupported strategies. CBAZA (94-95 mustang v8) does not support EDIS.

Since you need a tweecer or moates QH to modify, I can't proceed. My parts are in a box along with these wiring diagrams and down the road, If I do an MS, I'll revisit.

A good clean crank VR and 36-1 wheel install seems to be tricky to come by. I've seen a few setups, and not crazy about some of the compromises. (Machining balancers, spacing accessories, etc) so this is probably something I'll continue to research as it seems easier to do this when I have the engine out this fall/winter.

A cheap USB eeprom burner that will burn 27xx series eproms and the EEC Editor will get you there.

See https://www.google.com/?gws_rd=ssl#q=eec+editor+software+download&spf=1496001865767 for more information. If you are careful, you can do it for less than $150.

You get to unsolder the stock eprom and solder a socket in its place. Then you can pretty much do whatever you want using the binary editor and burning the code to a replacement chip.
