i got my ECU x over at 5100, but i guess that might b due to the fact that my car is less than 2k lbs. it pulls HARD.

 

how did I miss that . Hmm im stumped then

 

I know that the newer ECU's run faster. But what I'm saying is that something in the Jun ECU is changed that makes it not like the VAFC. Sorry, I'm not all that great with electrical engineering otherwise I could explain myself better. Of course the VAFC works fine with the newer, faster ECUs, how else would the thousands of people out there be running it.

 

False.

 

Was referring to decrease in performance.

 

I always have loved your one word answers. I just wish you wouldn't be so detailed about them, it makes it hard to take it all in at once.

 

from experience jun cams have a dip before vtec, but you just need to play with it on the dyno more and more and try this and that

 

VTEC flutter AHH get a JUN ECU p28 chipped and you'll be fine

Obviously some people dont know how to read the initial post. I have 1. a JUN ECU 2. a 2.5 inch coll and exh. and a 3 inch diameter short ram intake. I took it out to a desolate road last night and played with the V-AFC and I was able to tune it to the point were it is almost transparent. I leaned it out in that region and raised VTEC engagement to 6000. It feels alot better although I believe it is the Cat that is causing the dip, The cat I believe cannot flow enough at VTEC for the increased exhaust flow, I am building a testpipe at the moment and Will install it after the Manifold is on and go hit the dyno. I have heard all that crap about the JUN ECU not liking the V-AFC but I think it is crap, If I lean out the car in the top-end I feel a change, same as if I richen it up. I have had this setup for around a year and have only begun to notice the dip, come to think of it, maybe the cat is clogged, what do you folks think.


SGT, although I love your one word answers, maybe a little insight on how to fix this would help me, if you feel like it of course.
