Wheel inside distributor with inconsistently spaced/sized holes
Somewhat Common -- Complexity 5/10
Compatible EMS: MS-I with MSnS_E or MegaSquirt-II
Often these trigger wheels will work just fine as well. Remember you are looking for consistent trigger points (positions) evenly spaced apart. In some cases You'll have all trigger positions, usually holes on a optical trigger wheel, spaced evenly, but one will be larger than the rest. An example of this are Nissan 240sx and 300zx cars (probably others as well). Here's a wheel used through most of the 90's on the Nissan 240sx (KA24E). It has 4 holes, evenly spaced, but one hole is larger than the rest.
What's important to look for here is if the leading or trailing edge of the holes line up to be evenly spaced apart. So picture this-- the MegaSquirt EMS is not so much looking just at the hole itself, but at the beginning and end points of each hole. Where they start and stop. As long as one or the other lines up evenly all the way around then you're in good shape and triggering the MegaSquirt will be no problem. The above wheel will work just fine with the MegaSquirt-II set to trigger from the 'falling edge'. A 12v pullup on the ignition input is needed as well.

Ham her dropper de 360 huller og bruger kun de 4 store huller ->
Citat:
Here's the big one, the Crank Angle Sensor. It might actually be called Cam Angle Sensor, since it is installed on the cam, and rotates off of it, but since the outputs of it correspond to the crank and cylinders, I'll call it a Crank Angle Sensor. The VG30 uses a bad ass optical sensor. It is embedded in the distributor assembly and it is very easy to hook up. Be glad you don't have to hook up a ghetto looking crank Hall sensor. I mean, they are more accurate, but they are a pain to put on, and they look effing stupid. That's my opinion, anyway. Well, the VG uses an optical sensor that has two outputs. There's one for each bloody degree, 360 total, that the engine turns, or there's a much nicer 60 degree output. That is, the ouput signals everytime on a cylinders TDC. Whether or not it is firing. I think. Regardless of how it works, it's the one we need MS to use.

Hvis tendensen til at droppe de 360 huller er fordi ms ikke kan nå at aflæse dem korrekt (spørg HenrikGM eller MortenVJ de plejer at have styr på den del af det tekniske ) så var det måske en mulighed at lukke 4 ud af 5 huller så du har 72graders tilbage og åbne 2 af stederne så du får noget der minder om et 72-2 tandhjul. da knasten køre ½ hastighed af krumtappen og det er et 36-1 tandhjul jeg forsøger at lave (hvor du lukker de 3 af de 4 store huller og bruger det resterende til camsynck for cop og seq-inj)
