Mod-chipped. Stupid, yeah?

[depends]

My car has been modchipped before I bought it, and vtec kicks in at 4500rpm.

1. It's pointless/crap/too early
2. Would I be using more fuel this way?
3. I'm losing some of the vtec power, aren't I?

Can 'yes' be answered to all the above?

ps: yes, i'm getting rid of the mod-chip asap.

YES to all.
VTEC engagement is optimized by the engineers @ honda at those exact RPMs for a reason.

Just one thing.......

The stock vtec engagment for your VTiR B18C is 4400rpm at WOT so your Xover point has actually been raised 100rpm

Thankyou!

Hearing 'YES to all' is such a relief, you wouldn't believe it!

Yes, it's my first car and found that it's drinking a tad too much. Would it be quite a big difference? I mean, it's kicking in a whole 1500rpm's earlier! For normal street driving, it's so pointless coming in so quick.

What?! That can't be right.

Isn't the change over point stock about 5500 - 5800?

Does someone have the official specs for this?

not for the P72 B18C. 4400 is the official stat,i can show ya a vid of when i had a vtec light hooked up if u want.

btw,how can u tell its changin at 4500,when my B18C was stock i could hardly feel/hear the vtec Xover,the IAB change was much more noticable at 5750rpm

yup the butterflies opening did something audible to the VTiR's ive driven - and not VTEC

I can hear it. It's a very obvious change.

Car came with a cannon, and air intake (pod style).

[Rice_4_life]

wow how much do you get out of one tank then?

[depends]

Umm, I'm not exactly sure yet, but.. roughly 340-380km's?

I'll have to work it out exactly once i've finished this tank.

[daniel b16a]

thats alrite i reckon....my civic vtir gets around 420-450ks with full exhaust and extractor and pod filter...wait is that actually ok?

[NightKids]

Are you constantly changing gears at 4500RPM?
