99 jdm itr
short ram intake
2.5" catback
2.5" carsound
hondata


like 178whp and 124 of torque

redline was raised to about 8900 rpm even though my tach reads like 9,500 rpm the hondata reads about 9k, when vtec engages its alot harder kick then before, pulls much harder while in vtec before and pulls all the way through, dont have a scanner to get the graph online

 

what car do you have this motor in?

No piccy = No fun

I'd bet you could tune more from that setup.

Is it "like" 178 hp and 124 tq or are those the real numbers? jOO got a stock header?

Your right Anton, that motor is getting choked somewhere...

Harder kick? Your car was tuned right?

One objective of tuning is to gain some midrange (since we dont have any at all), a typical B series VTEC engine falls off in HP just before VTEC engagement, the idea is to flatten that hump out by making more power in the 4-6k range. That kick seems to suggest that you have a big surge of power on your dyno chart at whatever your engagement point is. That's not indicative of good tuning at all!

but yea...harder kick usually means losing power.

with a 97 jdm itr motor pulled

189/129 with:
Comptech Intake and Icebox
DC JDM 4-1 header
2.5 inch test pipe
and 2.5 inch stainless exhaust
97 JDM ITR ECU

only thing tuned was timing and fuel pressure

Now I just added: Kenji ECU and CTR Intake came and VAFCII, heading to the dyno at the end of the week

 

If I'm not mistaken, I believe all year JDM ITR motors come with the exact same spec intake camshaft as the CTR cam.

98+ JDM ITR's have the CTR intake cam, 96-97 do not.

I agree. Ironically though, I recall reading that a certain somewhat prominent "tuner" actually tunes so there is a large surge when VTEC engages, in order to make the car "more fun to drive".

Do you know if the same applies to a 98 B18C6 Euro spec engine?
Ours are mostly the same spec as the JDM B18C only we get the same crappy exhaust manifold as you americans?

 

i know it wasnt tuned to its best, it made 177whp 1 year ago with the same modifications but un-tuned. Its now tuned and made less power...., the only difference in modifications is it no longer has msd digital 6 ignition. They are the only hondata tuner in my area and my car was one of the first they"ve tuned with that system, i just wanted it not to be so rich and mess anything up. The closest other tuner that is very good with hondata is a 4 hour drive, i figured id just tow my car down sometime after winter when i get more mods and then have them tune it for max power. For now i just wanted to stop fouling plugs and have a smooth ride quality. My car was also very hot during the dyno time, my fan took a **** and they rushed the runs to get it done before closing time. I was hoping for much higher numbers but ill be returning for more tuning at a better tuning shop sometime before next summer with smsp header, bc3 cams, bc cam gear, comptech icebox, an exhaust they dosnt have corkscrew bends and possibly some itb's, better gaskets/seals.

motor only has about 16k miles on it and it is jdm, compression was 240 with 5-6 cranks all the way across, the last owner only owned the motor for about 6 months but he drove the car pretty hard, and it was un-tuned during that time so ive been trying to run cleaner products through it.

any kind of adjustments or replacement parts i can use to spice things up? Maybe he seals here and there...

Any-1 use sea-foam, i was thinking of running it through sometime next week, i know there has to be alot of crap and soot inside because it was driven un-tuned for like 5 months by the previous owner, it was just on a gsr basemap with very, very minimal tuning, what kinda products do you reccomend for cleaning it up inside?

 

maybe i missed it, but why was redline raised so high? is the extra couple hundred RPM really worth blowing the rods through the block? if you are on stock internals i wouldnt recommend keeping your rev limit that high. been there, done that.

 

called the shop the actual number was 172whp and 120 of torque, 5whp less then when it was dyno'd un-tuned less then 1 year ago while in the previous owners posession, only diff is he was also running msd ignition

and yea, stock jdm header

I don't see any reason why stock ITR internals couldn't handle 8900 RPM with the proper valvetrain (in fact, many consistently do). What were the circumstances surrounding your situation?

 

redline was raised that high because thats the way it was on the basemap they loaded, set for like 8900, i dont plan on taking it that high, i usually switch right around 8400rpm, thats where the power drops off anways, it dosnt make much sense to me either, id rather just have it redline at 8400 so i dont gotta worry about it, they didnt ask me, they just did it so im stuck with it for now
