1986 Ford F-150

1. Cylinder count
2. Injectors per cylinder
3. Crank input wheel
4. Cam sync/wheel
5. Mass air or Speed Density.

1. 6 cylinder 4.9 liters (300 cubic inches)
2. 1 injector per cylinder ( i only need batch mode for now)
3. No crank input yet
4. Even tooth 6 wheel leading edge, uneven tooth 6 wheel trailing edge
5. Speed Density for now...


I have a TA card (http://www.technologicalarts.ca/shop/sto...9s12x.html) , a dual 5 volt regulator mirrored from Jaguar ECU pdf, and a max9926 attached to breadboard(like Jaguar's pdf), and also JBPerf Dual VR V2.0 if needed.

I tried to get emsstudio to read my rpm using a modified (syncless) version of freeems-ecu eventooth decoder but it wouldn't read the rpm.

Nice, do you have any more info on this:
4. Even tooth 6 wheel leading edge, uneven tooth 6 wheel trailing edge

Maybe pictures at least?

a. the login captcha form is out of control, it did not want me to login. i use noscript and i kept unblocking but it was the worst i've ever seen it took me 30 minutes because i failed twice to login. the captcha isn't bad but please disable the timeout system immediately.

b. i was wrong about the uneven tooth 6 wheel trailing edge. it seems the later model f-150 have this though i don't remember exactly where to read this or find it out. it is all 6 even teeth.

c. the system is not hall effect. the system is a Variable reluctance sensor. of a permanent magnet, a trigger wheel that blocks the magnetic field, and a coil of wire to read the system.

What exactly is needed is a 6 tooth even wheel decoder. if you can help me do that then i would be extremely grateful.

Hi Nick,

Can you provide a picture of the wheel out of the distributor housing? We might be able to get full-sync with it, even if it's not there is no reason that we cannot use that "CAS".

Thanks,
Sean

Is that wheel FULLY symmetrical all the way around (all "flags" and "gaps" the same, or is one different in size?)  If one is different we can use that as a Cam sync source.  If you can get another distributor of the same type and feel like modding it we can have you cut one tab shorter than the others to provide cam sync, which gives your many more options (coil on plug, full sequential, etc)  Another option would be to weld on a single tab facing outwards and adding a sensor to read it as the cam sync source but that requires significantly more skill to do, which you may or may not be comfortable trying to do.

6 vanes and 6 air gaps total degrees:: ( 27.2 degrees + 31.80 degrees ) * 6 = 360 degrees


That is my best measurements. I am still trying to get the max9926 to read the signals from the napa module into the modified free-ems ecu i have connected to my laptop via EMS-studio.

I just redid the max9926 circuit to replace the max9926 i think i burned out previously. Will test today.

Cool, thanks for taking those measurements. In your case we should just remove one tooth and that will give you a full sync decoder Smile You can still use the distributor for ign like this.

The distributor's module relies on the tooth to fire the sparks .. how will removing one help?

My comment was assuming that you use LibreEMS to control both fuel and ignition (sparks).
