Yeah,..... but what are you looking at doing next!? :D

You only need a fuel only ecu for this, you've already got a dizzy.

if your going to go aftermarket ecu, you may as well get one that does fuel and spark (unsure what you do about CAS on k motors, but I'm sure its do-able). then you can fiddle with the ignition timing too.

 

IMHO if you only need to pay an extra $50-$100 to get an ECU with ignition control you'd be silly not to. It would make a bit difference in tuning scope.

 

All you need for an ignition trigger to the ECU is an external ignitor electronic dizzy. That then gives a pulse to the ECU, which it can advance or retard, and then send a "fire" pulse to the coil via an ignitor.

he already has a fuel only unit so if he want's to get started on the cheap then he's ready to roll!!

Yep sounds like wacking the F7c on might be the best option for now.. i dare say ill end up trying a few setups, but thats no doubt a good place to start.

my only other train of thought toward carbs is in the future when it hits the track.. I'm guessing that having the efi could put it out of some potentially competitive classes?

seems to be a pretty well done package all round and certainly has potential from what little driving ive done of it!

Efi would be the way to go Id say! I will be going efi with a supercharger later on down the track! I spent well over $1000 on setting up my twin carbs! I just recently had to get new needle and seats which took abit to find! But I am very happy with it! Love the induction noise! :lol:

External ignitor electronic dizzy you say.. would this describe the usual K motor electronic unit (terribly pictured below) or is it more complicated?

I would assume that the block on the side of that dizzy with the wires attached is the external ignitor? Can you get a better pic?
