Hey guys,

My lil bro has a dc2r, been having this problem not too long ago.... vtec's not engaging at all but when it hits 5900 VTEC comes on and go all the way out.

Took the car to hondatech at thomastown for a check up last week, got the vtec solenoid clean and they checked all the wirings and ecu nothings wrong with it.....

what else could it be?

Wait what?. Vtec is not engaging but at 5900 vtec comes on???

Is the car stock standard?. Need more info please... Standard Computer>?

Do you mean its engaging to late?

errr thats how vtec works you noob its not a supercharger or something. it engages after a certain rpm lol

*Vtec is not engaging but at 5900 vtec comes on??? * lol....

vtec only comes on around that rev range

nah......

if ur dc2r is stock or still runnign stock ecu, vtec will activate at around the 5700, 5800, 5900 mark, depending on rev tachos and engine wear....

so as long as ur vtec comes on and stays on till redline, there is nothing wrong with the car....

just enjoy it.............................

the only time vtec will not engage, is if the water temp is not warm enough, and or if u have low oil level, which will cause not enough oil pressure to the vtec soliniod and not engage.....

p.s. please dont take ur car to hondatech in thomo again......................i wont say anymore than that...

OKAY thanks bro,

dc2r is running stock ecu, just got full exhaust and pod.... maybe this is normal then.

B18c2 engines.. vtec kicks in around 4500 then a secondary butterfly opens up around 5800

b18c7 (dc2 type r) engines.. vtec kicks in around 5900.. no secondary butterfly

so i'm assuming your EK would be a b18c2 (you can tell the difference between 2 engines by the intake manifold.. b18c2 intake manifold is reversed)

and it will come on at 5800.

you wasted money getting the solenoid cleaned for nothing?

the EK must have vtir motor:p

Vtec will come on at different RPM's on different cars, please research this before you embarrass yourself more.

sorry to dissapoint u but its a JDM B18C.... VTEC activate at 5200 then 5800 the second runner will open up.JDM b18c has no secondary butterfly and VTEC comes on at 5800.

no higher, no lower.

Well, normally dont VTEC's activate at 5200rpm? until 5800rpm then the secondary runners will open up?This is the case with AUDM vtir & JDM Sir-G.

They both have the dual stage intake manifold.

Vtec comes on at 4200(I think) and Secondaries at 5k+.

REPEAT - TYPE R'S DON'T HAVE DUAL STAGE INTAKE!!!!!!

sorry to dissapoint u but its a JDM B18C.... VTEC activate at 5200 then 5800 the second runner will open up.then you don't have a type R motor.

Sorry I just had to comment on this. The Noob OP is just too funny.

States funny stuff (VTEC on and then off and the no VTEC and then secondary intake then VTEC then what??!).

Then says 'yes I know my motor inside out'.

But before that says 'sorry to dissapoint u but its a JDM B18C.... VTEC activate at 5200 then 5800 the second runner will open up'.

Then says (in summary) 'errr maybe it's not JDM, maybe whatever. Maybe you guys right me wrong, or maybe I'm smart and you all are dumb'.

Open up your mind boy, you won't learn anything with an attitude like this and will continue making funny mistakes just to prove your point.

whatever u say is rightmate, its not whatever we say.

Its actual experience in dealing with the above said.

I've worked on a vtir manifold & a type R manifold.
2 different designs, not what i read off the net mate.

I've actu7ally taken an electrical signal from the vtec solenoid to see when it actually come on, instead of "but I thought I heard it come on at 5200 & baaaaaaaAAAAAAAAA at 5800 and VRRRRRmmmmmmmm all the out to redline."

As I dont have much experience about honda, and i do agree with the comments that has been posted on here....

But then I was able to reach the 120's kw atw (dead stock) so i cant say its a vtir.... and also i was able to fit the b18c7 skunk2 im onto my motor (it was a straight bolt on)........

A skunk2 manifold is a copy of the dc2r manifold...lol..
Changing the crossover point in a stock engine (no internal work) will make you lose power, these vtec controllers are all useless unless you have aggressive toda spec c's which the optimum point is even higher at 6k+ or so redlining all the way to 9k, also the controllers (apexi,buddyclub etc) arent piggyback ecu's.

Just to clarify, coz it seems some ppl are getting all mixed up, although I can see there's a lot of confusion and misunderstanding with OP and everything...

OP's brother or whoever, has a DC2R and VTEC comes on only at 5900rpm... he's asking if there is something wrong...

OP himself has an EK with a B18 of some sort which has 2 butterflys... OP thinks his B18 is a Type-R B18 as it came out of a 98spec R... Maybe original 98spec R owner put in a VTIR B18 into it for some reason... but that's irrelevant. OP probably doesn't have a R motor like what everyone else said...

To answer the DC2R question owned by the OP's brother... there is nothing wrong with his DC2R and the motor... VTEC in a B18C7 will come on at 5700rpm and continue through to redline... that's it.

Talking about your own B18 in your EK has nothing to do with your brother's B18 in his DC2R as they're obviously different B18 motors.

Goodwork everything was so unrelated.

B18C7 vtec is 5700, although it will appear to be 5800-5900 on your cluster purely because the cluster is not extremely accurate and you can't tell 100-200rpm on full throttle. Considering the engagement is done in 1/10 of a second.

Also there is sometimes where vtec won't come on anyway (to avoid engine damage), because of cold starts when not at normal op temp.
just make sure the car is warmed up (oil temp is stable/water temp) as long as your car isn't running in startup mode [sitting just tiny bit left of the C on temp gauge], with full throttle it will engage around 5800 on your cluster. Apparently you can kinda still be in it when half throttle but to this extent i don't know really. Could just be high rpm so car is loud.

If you have a vafc its a little more accurate than the cluster, it will show a more true rpm. All this is just from own experience, there is something i missed out too but forgotten at this point in time.
