My friend has an ITR and he is going to buy a Jun Stage 3 Head from another ITR driver. The other driver is including the Jun ECU for an extra 600$ . Is this ecu worth it? For my info sake, what does the Stage 3 consist of, and what does the ecu do. Thanx alot guys!

 

The JUN III's are just camshafts, unless he is getting the whole head package...vavles, retainers, springs, sprockets, etc...The ECU is a worthwhile upgrade especially when running such aggressive cams...It remaps the fuel settings, vtec engagement point, rev limiter, etc...

 

That ECU works extremely well with their cams!!
