hey guys i just finish up my ls vtec setup and now i cant rev up past 3 rpm. does anyone have these problem before and how did u fix it?

 

What happens after 3grand? Does your car die, stutter? What happens.

 

Have you done any mods to the ECU? Did you wire VTEC properly to the ECU?

 

before 3000 rpm the needle just drops and thats when i push back the clutch..and the vtec wiring is not connected yet but does that effect what is happening to my car? and i bought my ecu from pherable so yea.

 

I don't know first hand, I would suggsest you wire VTEC and go from there, I can almost guarantee that is your problem

 

can it be like my sensors?

 

does vtec kick in at 3k rpm? if it does then it is probably your vtec wires not being connected that is causing the problem.

 

its set at 4500...and can it be the iavc sensor or hoses connecting at the wrong places?

 

i think its the fuel injectors because everytime i gas it hard or fast its just the rpm just drop and about to die but it doesnt

 

you should check your ecu i had the same problem with my ls vtec i told my buddy to let me try his ecu on my car and it ran good but when we tried my ecu on his car it would go over 3 000 rpm so if one of your friends has a vtec ecu try theres on

 

maybe a loose ground???? are you getting any codes from the ecu??

 

i try my friend gsr ecu and it does the same thing so count that out..i clean my fuel injector count that out too...but i do have cel on but dont know what its showing...i think i dont have the 16 pin plug thing for the scan because i look under my dash near the fuses and its not der i guess when i bought it sumone took it out..

 

The SCS connector is what you need to find, passenger side. Jump it will a paperclip and you'll be able to read the code

 

i cant even find the scs connector either..can u help me with any pictures or diagram

 

It is located above the ecu under the dash. It is a small two prong connector with two wires, the plastic part on mine is blue. It may be a different color I don't know

 

sonnds like fuel for sure, did you happen to change the fuel rail by any chance

 

its your vtec not conected fo sure just try it by puting a wire on the silinoid and to the battery and rev it and come back if it dose not work . pease

 

i didnt not change my fuel rail mostly everything is stock.....and with the vtec solnoid i wire it but when do u konw its working cuz when i wire it u can heard clicking sound does that mean it working?

 

i know ur problem when u did or who ever did ur timing they didnt do it right! so its just timming check the exuast cam thank u come again and if iam right pm me thnakz u come again

 

the white mark is the tdc and the camshaft should be pointing upwards rite?

 

yes correct but listen on the exaust cam theres markings and on the intake like two lil lines make sure those are alined with the arrows pointing up
the exaust one will look a lil tweeked out not pionting up but along its alined with the line ur cool
