Next time your at the dyno, set your vtec at 5600~5800 you will have a nice smooth transition when it kicks in. Right now its set to low (yes stock is low) and it has a pretty good dip in power. On my ls/vtec turbo and crvtec high cam was set at 5900.

And damn, pats making more torque than you hah, Most b16's lack the torque.

Good job kevin,

yeah, i just got a chip burner, so i'll be able to mess around with my tune some now, at least i have some base line numbers and i figured out my exhaust was definitely killing me and i had no idea of my afr's for 6 mos., at least now i know where i stand. i hope to have close to 300 in a month or so

That .60/.63 is really going to be running out of steam at 300whp. Dave was around 15psi and made 289 on his b16a with ITR cams and ITR IM.

Definatly time for a turbo upgrade

projekteg

good idea

Stan

Get a new t4 wheel and I have a nice to4e compressor housing for ya.

Kevin, pm me with your msn addy.

teg you might consider the stepwise retard instead of just retarding it 1 full degree throughout. Blundar has a lil formula thats on the uberdata tuning forums. Check it out.

http://www.ecimulti.org/uberdata/for...y;threadid=716

13.5 AFR while NA. 28 degrees timing at boost/NA transition peak power production. Timing retarded by 1 deg / 1000 RPM on top side of RPM band after peak power production.

12.5 AFR from 0psi to 3psi. retard 0.25 degrees cumulative by 3psi (i.e. 0.08 degrees/psi)

12.25 AFR from 3psi to 5psi. retard 0.75 degrees cumulative by 5psi (i.e. 0.25 degrees/psi)

12.0 AFR from 5psi to 7psi. retard timing 1.75 degrees cumulative by 7psi (0.5 degrees/psi)

11.5 AFR from 7psi to 10psi. retard timing 5 degrees cumulative by 10psi (0.75 degrees/psi)

looks good kevin get that baby tuned up and let us know what she does then. im hopin to put down around 300 hp on my b16. well when i get my turbo :P

yeah, i'm aware, i just haven't done any tuning to it yet, but yeah, i plan on running as much timing as i can get away with, 1* per psi is a lot! that and the coler plugs is prolly the only reason i'm not detonating when my afr leans out to 13.5 under almost full boost :P

hell yeah, some tuning is definitely in order. i took my whole exhaust off right after this and running open dp, damn, what a difference!! *** dyno says i picked up at LEAST 15-20 whp!! my exhaust set up consisted of a 2.5" dp, straight to stock cat, right after the cat, the exhaust hit about 1.75" for a very small section, and then opened up to 2" crush bent the rest of the way, so you can only imagine how restrictive that was for a turbo :P i'm also getting a clutch this weekend and filling in my motor mounts (every single one is tore to pieces), and i'll be hitting the track next thursday.

hey kevin, i know this guy in town who has an old lap top equipped with uberdata, and can do some datalogging as long as the ecu is ported for it...you can use it anytime :P

and i pmd you about the clutch...should be getting it tonite.
