can someone help me!
why my vtec no working and i have check all my wiring, sensor and switch all working fine...
i have change ecu too (P30)

 

how do you know its not working? you know vtec isnt really that big of a difference right? its not like as soon as you enter vtec you gain like 500 horsepower..

 

cause i try on my own and friend vehicle, while i accelerate to 3500 rpm i have 12 volt reading at multimeter for my friend vehicle and my reading only 2 volt plus. both same vehicle.
and the power of both car are totally difference

 

try cleaning the screen on the vtec solenoid and check your wiring again

 

i clean vtec solenoid before.. ever swap vtec solenoid with my friend and working fine on his car. BTW wat wire should i check again

 

is there anything do with CEL no.20 (ELD) causing vtec no working??

 

help help

 

check your ground wires....with code 20 it seems your having some electrical issue

 

i add 3 more ground to my car ready.. by the way my car don't have ELD but ecu have, do is affect??

 

switch ecu and see what happens...and btw what motor and car is this?

 

wat ECU should i try and i drive eg6 engine B16a

 

try a stock b16 ecu. or even an ITR...best way to go if you have it is a chipped p28 and find which basemap runs better on your car by testing them out. sometimes swapped motors with stock ecus run funny even though its the ecu for it. chipped ecu is the way to go.

 

got anything to do with ELD. CEL 20

 

bump

 

your car might not have it but the ecu might, so its looking for it and of course the CEL will come on if the ecu cant find it

 

so now wat should i do, buy the ELD system to fix it or find a ECU without ELD and suitable for DOHC vtec engin??


pls help

thks bro

 

try a chipped ecu with a basemap for your motor.

 

wat chip should i use??

 

what do you mean what chip? you mean which basemap should you run?

 

yes wat basemap i should use??

 

well i would say try a stock b16 map first. then if it's still the same try an ITR basemap

 

thk bro

i go try out hope it well work
