....bump i have the same problem

petersayarath

chipped p28..with custom program.. but its the same program when i was NA

petersayarath

ohh yeah BTW.. everytime i hit vtec (5700) CEL comes on and it reads code 21.. vtec solenoid? could that be bad?

Luserkid

Code 21 usually means the wiring. Check your wires makes sure there good. If they are take off your VTEC Solienoid and check the screen thats in it, make sure thats clean. If you didnt touch anything electrical putting the turbo on you shouldnt have a problem. You and nekoabandoned. I dont understand why your VTEC wouldnt be working.

petersayarath

will do.. anything else"?

well im throwing a cel 41(o2 heater wire) but i dont think that would cause mine not to work by the way can u hear the vtec nod clicking when u get to those high rpms? i can hear mine like its my rode trying to punch a hole in my oil pan(stupid clicking thingy) .....is the vtec clicking bad?

petersayarath

i dont hear vtec at all.. it doesnt kick in and it feels harder trying to get near redline. like its struggling trying to climb to higher rpms after 5700. like i mean it takes longer or feels like it is.

i tried the battery trick where u hook up a wire to the + battery terminal and to the solenoid green/yellow wire and it clicks..

petersayarath

i'll check out my wire connect and everything tomorrow

Did you maybe hose up the oil pressure to your vtec solenoid when you ran your oil tap line?

petersayarath

i tapped the oil right behind the oil cap by the dizzy..? where the ally wrench 3/8' bolt is.. is that it?

SOHCD16y8

Wait you tapped your oil supply for your turbo there? It really should come from were the oil pressure sending unit is on the back. That is probably your problem.

JdmB16Eg6

**** when i went turbo, vtec was dead, didnt even hear it, just spool

LVB18Civic

Change your oil feed to the oil pressure switch off the back of the block. That is most likely your problem.
Also I would get your setup tuned asap. Running a N/A tune is asking for bad things.

thats probably your problem, vtec probably is not getting enough oil pressure to engage. you should also check your turbo, probably filled with too much oil as well due to you tapping vtec oil pressure. you should tap the oil pressure in the back

petersayarath

oil pressure sending unit in the back on the block right? underneath the manifold?? by the oil filter?

i connected to the back of the block but im still not getting vtec.when i set the vafc to kick in at 3.5k(i know its a low number)but i still hear the damn clicking.i know its coming from the vtec nod,although i do smell oil burning when the turbo spools help me! ......bump

hoya_10fintec

bump on this, cause I never had vtec either... well I kinda did..

everytime when vtec activated, the engine would strugle, bog, and strugle some more with no engine light. tried everything to make it go away... didn't work.

sorry if I jacked your thread.

#1 get rid of VAFC

You smell burning when the turbo spools? thats bad mmmmkay

Vtec requires oil pressure and coolant temp then ECU signal. Also I would clear up any CEL you get (cel 41) before expecting anything to work. Do you get the MAP sensor CEL when you hit boost with the VAFC?

thats bad

If you have a chipped ECU already go the extra mile and get a moates burner and chip and start tuning with crome.

petersayarath

whats a good burner?? anyone you guys recommend??

i put turbo on my LS/vtec worked fine.. i taped my oil for my turbo and my vtec right out of the back of the block and it worked just fine...
