Vtec Controller

[Slow89Civic]

I was wondering if this controller was any count.... http://cgi.ebay.com/ebaymotors/Buddy-Club-V-Con-VTEC-Controller-92-95-Civic-EG6-EG_W0QQcmdZViewItemQQcategoryZ33596QQihZ017QQitemZ 270011802150QQrdZ1
I have a D15B and I was wondering if I could install this or would I have to have it professionally installed, my vtec kicks in around 4500 now but it has no bottom end, could I make this kick it in around 3000 rpms? Would it really be worth the $60 bucks or is it pointless? thanks for any input.

how does your vtec kick in at 4500 now? however you adjusted it you could adjust it more but realyl i wouldnt go any lower than what your at....

[Slow89Civic]

Yea it kicks in at 4500 now, it just has no bottom end and it is so weak until it hits the vtec. I'm gonna set it at 4500 or higher for daily driving I just wanna make it kick in sooner if I wanna show out or something lol

sounds like your ignition timing is off. Have you been twisting your dizzy?

Whats a dizzy? :(

i have a d16y8 and installed that controller yesterday. my vtec normally kicks in at 5500 and i have it set now at around 4500. when i set it any lower than that my check engine light would come on after a few crossovers and wouldnt rev past 5000. so i adjusted it and reset my ecu. But what happens is if its too low your ecu goes "wait, vtec isnt supposed to kick in yet" and stops it lol. but i think its worth it..... it just doesnt adjust your air/fuel like a SAFC would do.

[Slow89Civic]

So could I hook this up myself? Would it stay set at 4000 for a quick race and be ok? :cool:

[jangalang]

if u know somewhat about eletronics and what not.. its not hard. maybe 30mins if you know what your doing! if not, get someone to do it cause its your ecu.

[jimmyb34]

what have you done to get it to activate at 4500 now though?

[jangalang]

thats what i want to know. why his vtec kicks in at 4500? is it an auto?

[kahtontah]

Yea what did you do to get it kick in at 4500 i am curious, and does this vtec controler adjust your fuel/air mixture to maximise power

[jimmyb34]

vtec controllers dont adjust anything but vtec...
i wouldnt go any lower than 4500.. making your vtec lower doesnt make your car faster.. there is a fine line where going lower hurts itm ore than helps

[EG-nath]

you can get a vtec controller for the dohc that alters fuel and air mix. aswell as sohc. one for dohc is vafc

It's a freaking honda, it won't have any low end power. Vtec isn't made for bottom end power its made for top end power. Lowering it below 4500 would be stupid and probably blow it up.

[azncivic]

^^^also if i made add...lowering it or setting it to lower rpm..let say around 3k .you'll lose some top end..unless you spray it then it'll even out.

[Kutsuju Racing Pres]

it's a 1.5 that's why it has no bottom end....probably 80 something ft lbs of torque....

don't go any lower then 4,400 I'd leave it where it's at....the lower you go the worse your top end is gonna get and your also gonna have a crappy mid range....if you want more power go boost! or cam or something worth while but lowering you vtec more is not going to gain you anything....you'll loose out in the end.

Whats a dizzy? :(
Well the dizzy is the distributor. It controlls the ignition timing in hondas and is the thing with the spark plug wires on it. ( 5 of them) not to be confused with the head(4)/ You can advance your dizzy + or retard it - a certain number of degrees. You can also do this with the cam gear if you get an adjustable one. Stck to the newb forum for a while till you learn the basic engine parts.

I use the Apexi AFC NEO and set the vtec to 4000rpm, and it works damn good.
you just need to add the vtec unmatched +12-15% and add fuel in the rpm range from +2 to +15% then after 5500rpm go down to +1...2% at the redline

[jimmyb34]

your probably losing power and tq doing that.. thats to low of a crossover.. lowest id go is 4800... most guys with cams are in the 5000-5500 range....

[HondaHRV]

I don't know if I am loosing power, but the car runs much faster than before.
If I set the vtec to 4800rpm, when I change from second gear to 3d, it drops to 4500rpm and it's below vtec loosing a lot until the vtec engages again.
maibe I will set it to 4300, but not higher, because the gear ratio drops the rpm too low.

First time I have tried with lower fuel add, and it did not run well, when the vtec was engaged by the AFC it sounded weird then when the ECU switched the VTEC map it has changed the sound again.
Now with more fuel at the vtec engagement and a higher VTEC unmatch correction sounds very good and when the ECU switches to VTEC at 5500rpm there is no big difference in sound and power.

[jimmyb34]

there isnt supposed to be a big difference in power and sound when you hit vtec.. its supposed to be a linear crossover.. not some huge burst of power.. i GUARANTEE your not making the power and tq that you should be with it at 4000 and still wont at 4300.... i was at 4800 for a while before my cam and i probably should have raised it.... now im at 5k with a cam

[HondaHRV]

I feel the vtec in two stages now, it's not a big diffrence, but there is a different sound when the vtec controller is switching to hi cam and a different one when the ECU switches the map for hi cam profile
Maybe I am not making the best power possible, but the car has very good launch and when I change gears the rpm is always in the hi-cam profile and is very responsive
If I set the vtec point to 5000rpm the gear change drops the rpm to 4500rpm right in the lo-cam area, and it sucks, it takes a lot until the vtec engages again.

[jimmyb34]

the reason for hearing 2 different "stages" is because your not compensating for the fuel from 4000-5000 when the vafc switches over the cam... then you get the power back when the ecu switches it over....

[HondaHRV]

I have set the VTEC unmatch which does this correction, from 12% to 16% and now the sound difference is lower, but it still exist.

I have a 2002 engine which uses OBD-2 with 2 oxygen sensors and one EGT, it is possible that my ecu is smarter and it is correcting the AFR better

[HondaHRV]

what are your settings for the air correction on the afc ?

[jimmyb34]

i dont have a vafc.. i run a chipped ecu with crome... the correct way to do it..
but you being obd2 would have to convert to obd1 to run a chipped ecu
it is possible that your ecu is trying to correct things also

[HondaHRV]

the correct way is a Hondata programable ECU, or a standalone engine management, but for the price of the AFC I think it's ok.

[jimmyb34]

the correct way is a Hondata programable ECU

im running crome pro... has all the same features as hondata..... you have to chip you ecu WITH a program to tune it...

[HondaHRV]

I did not hear about crome pro, but if you need to take out the chip from the ecu to program it, then it's not very good, because it takes a lot of time to tune it.
From what I know Hondata has the best features a Honda can have still using the Honda ECU

http://www.pgm-fi.com <----- Check it out it has info on all the different tuning programs available for Hondas. You can't bad mouth something you know nothing about.....

[HondaHRV]

it is http://www.pgmfi.org not pgm-fi.com
I know uberdata, but it does not have the features of hondata (like gear change ignition cut, launch control, turbo anti-lag system) and it's full of bugs

[CIVICRicerBoy]

Ok. Just saw this. I have the Buddy Club VTEC Controller. I love it. It's pretty amazing. I have mine to kick in around 5500 or 6000. I recommend it.

[93civiccx]

Crome is the best way to go. To truely tune something right you are gonna spend alot of time tuning. Hondata is old school. I don't really know too many people around here that are still using hondata.
