FUK YHEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE EEEEEEEEE!!!!!!!!!!!!!!! guess who got the Vtec workin?????

ME!!!

thanks heaps everyone..

it ended up been the computer not putting enough voltage to the solenoid :S
so just went to jay car to find something to fix this problem, so i got a thing that creates more voltage from any volt, my comp was only putting out a max 6 volts to the solenoid.
now i can control when i want it to kick in. iv only set it to kick in at 5400ish.... but dammmmmmm it revs so much harder all the way to 9000rpm and the sound --HOLY FKNSHIT!!!... its insane...

thanks again to everyone

SOo, the overal problem is the ECU yeh?

thats what im thinking hey,

took it for a hit tonight and found out that the car runs funny on lower revs.
also the vtec sound doesn't sound like it suddenly kicks in at 5400rpm,
as soon as i put my foot down (no matter revs) it sounds like the induction sound of vtec but softer until it gets up and goes, the sound gradually keeps going louder and louder till 9000rpm, also its alot more sluggish on low revs..

me thinks, that vtec is now on full time or kicking in wayyyyyyyyyyyyy to early

any inputs would be good.. thanks,

its prob a vtec converted ecu like a P06,P29 etc
could be just a bad solder joint or just bad component on the enabled vtec circuit.

ecu just looks dodgy in general from that one pic anyway
put up a pic of the top left hand quarter of the ecu board
if i was u,i would just dump it & find a factory vtec ecu like a p30 or even chip a p28,p72

contact ECU-MAN,i do believe he has some spare socketed vtec ecus available

its a chipped P30, but alllllllll goooooooooooooood now. its wasn't the comp after all :P just shit wiring, wires going to places it shouldnt be. now i get Vtec yo and better fuel consumption. also cleaned up the wiring heaps and made sure all the connections were 100%
thanks again everyone for your help.

and special thanks to CRXrer and the dude at TODA performance...
