haltech smallport 4age CAS

[cri_ag]

i have an e6k and a 4agte motor running a smallport head. now ages ago 1jz-rola or maybe it was takai? told me i could use the smallport dizzy and its 24tooth trigger wheel and single tooth home trigger. im curently doing the wiring but im stuck on the dizzy.

i have found a little info from the old fourms here

but im still stuck. there are what looks to be like two single tooth triggers in the top and the 24 tooth wheel in the bottom. how do i make this all interface with the haltech?

You dont use the second "bottom" single tooth trigger. You only use the one which is TDC. The other one is 180* out from TDC.

Wire the TDC one up to home trigger, and then the 24tooth up as usual.
Ill see if i can post the wiring i used when i get home.

please see my thread in the FAQ about toyota ignition systems.

mate if you could post your wiring it would be greatly apreciated! how do i figure which is the TDC trigger?

[takai]

Its the top one. Line up the TDC markings on the dizzy and you will see.

Takai = correct.

the 24 tooth sensor has red and white wires
the TDC home sensor has yellow and white wires.

the white wires of each are the signal earth.

hmm dident find that one in my search! cheers.


thanks again takai, i need to spread the rep b4 i give more to you!
bugger i cant rep witzl either!

Ah, so its supposed to be Yellow/White. On mine the white is so faded/crusty that it looks yellow too. That explains a lot

ok i just put the dizzy into the head and the trigger that is on top has a green and white wire into it? im confused. ill take a picture.

[cri_ag]

ok here is what im on about, green wire on top, takai said it was the trigger ontop that i wanted but the yellow one is on the bottom?

If you still have the plug on it this may help to know which is which. http://www.toymods.net/TechDocs/4age...stem/ig_08.jpg

In microtech wiring the yellow wire doesnt get used. Im using the smallport dizzy as a CAS on my 4agte.

Then use the one on top, green wire it is. I just had a look at my two CAS's which are easily accessable and one has the yellow on top and the other has the green on top. Reasonably fickle i believe.

Will take photos soon, camera is still charging.

[cri_ag]

how do you set the dizzy to TDC? only instruction i can find is here

and belive that is refering to the bigport motor as my dizzy has different markings.
ahh this is giving me the shits!

[takai]

Ill take a photo when i go past home soon.

you should still have a tooth with a notch or some kind of marking on it, and this lines up with the mark on the dissy shaft casing.

get engine to TDC compression (the 4age book link you gave works fine for this) and insert mr dissy as per the 4age book instructions
