Hi Dave,

              Those COPs I used are still on ebay for less than $ 17.00.   They are stocked here in Australia, so it only took 3-4 days to get hold of them, & postage was free !

very nice work. I'm doing my second 'learn to solder' project and the next one I buy will be  a megasquirt I reckon....

What options have you looked at for crank triggers?

I am also about the pull the trigger on a megasquirt purchase:)

Not a bad price on those yaris coils, i might do some measuring. 

 

 

 

 

 

you going to DIY build it Dave?

Considering it. How hard can it be? Solder the things, let the smoke out of them....wait.

jeesus christ and here i am thinkin I'm all clever workin on making my carburettor automatic variable mixture.

this is just insane.

total respect from me here, I'm impressed, i don't think i could bring myself to manufacturing all the parts to make this engine efi or electronic spark.

just seems so difficult

I finally got my 4 Wire connectors yesterday, for the Echo/Yaris CPOs, I am using .  What a drama !

 

Just wiring them all up on the head & frame I made.  Used a micro programmed to four outputs, at any rate (rpm) I want, & with adjustable dwell.

Went searching for what sort of input voltage/ current is required for the IGT (trigger) input.  

Came across this video.

If you are interested in how the COP system actually works, as a few respondents to this post have; then this video is a must.  It actually refers to the Toyota COPs used on the Echo / Yaris.

Cheers Banjo
