im in the proccess of lsvtec and i have no ******* clue how to wire this be-otch... is it possible to use the stock ecu and the v-afc2? or does a vtec ecu HAVE to be there? please tell me i can wire this thing with the stock ecu!!

LSTEG96

bump, please, god! let there be ONE smart guy out there, that says "hell yeah man, u dont need a gsr ecu!"

LSTEG96

bump?

3 am bump...scared, lonely, tired, confused

Yes it is theoretically possible to wire it with a VAFC, but I'm not sure how exactly. I would spend the necessary cash and get a VTEC ECU.

jus do it the ghetto way and get a msd rpm activation switch . i think it would be easier to get a vtec ecu .

how is the vtec solenoid activated?

mr.beeks

yes it is possible
but if you want i have a p28 for sale..

**** that, im broke...wanna tell me how? whats the 2 plugs coming out of the solenoid for?

mr.beeks

duh!!!

positive and negative

ground one and the other to the v tec controller on the VAFC.

ur a god.... i was thinkin somethin ALONG the lines of that...

and hey now, ive never been inside a motor, im 17, had my car for less than a year, and im doing ls/vtec

LSTEG96

wait, theres still one more wire...

It shows.

Im going to assume that you have utterly no idea what you are doing and suggest you get a Helms manual

the list of possible problems based upon your complete lack of knowledge on the wires required to hook up vtec is quite long... Get the manual and figure out what exactly it is you are doing.

I hate to rain on your parade but

ok, thanks?


i got the wiring diagram for the gsr, theres a ground and one blue/black wire going to the ecu from the vtec pressure switch

and a green/yellow wire going to the ecu from the solenoid...

can someone explain what actually turns the vtec on... pressure switch or solenoid?? and why would the OTHER one (that doesnt turn on the vtec) run to ecu?

jdm91integ

Using a v-afc to engage vtec instead of a vtec ecu is called "One Wire Vtec". To do this you need to look at the wiring diagram in the directions that came with the vafc-2. There are diffrent diagrams for diffrent obd's. Find the right one for your car. Hook up everything how the directions tell you to except for the vtec signal wires. Instead you want to take the end of the wire that's connected to your vtec solenoid and connect it to the vtec solenoid signal output wire on the V-AFC. The vafc will now turn on vtec at whetever RPM you set your vtec engagement at on the v-afc. The downside of "One Wire Vtec" is your fuel maps are really lean once vtec comes on. I think this can be corrected though, by tuning the v-afc.

The solenoid turns vtec on. The pressure switch is used by the ecu to make sure there is adequate oil pressure before turning on vtec. This is why if your oil is low vtec won't engage.

Ya, good luck with your Ls/Vtec project. Make sure everything is grounded well and there are no loose wires that could come undone. What head are you using? Who ran the Oil Pressure line for you? Sounds like you should give us a run-down in a new thread before you make any attempts at starting your motor. An Ls/Vtec swap ain't easy bro

haha, ive got a lil help from a friend... the oil line is a flameco oil line kit thing... a run down? what do u mean? step by step pics?... im starting this from the build up, not tearing it all apart, just putting it together...

I SUGGEST YOU GO FOR THE CLEANEST STOCK INSTALLATION. THERE'S THREE WIRES FOR THE VTEC TO RUN. THE HELMS ACURA INTEGRA MANUAL HAS THE ILLUSTRATION WHERE TO PLUG THE WIRES FROM THE VTEC SOLENOID TO THE ECU, THEN FROM THERE YOU CAN PLUG ALL YOUR HARNESS FOR YOUR APEX CONTROLLER. I SUGGEST ALSO TO GET YOUR ECU LIKE P28 OR P72. LS/VTEC IS NOT MEANT FOR HIGH REVING, SO DON'T REV IT TO MUCH YOU WILL HAVE AN OIL LEAK IN 4 MONTHS IF THAT BECOME A HABIT.

Mann somone shoot this guy!!! If your doing one wire vtec just run the vtec wire from the vafc to the vtec soleniod thats the one with one wire coming out of it...
The other one is the vtec oil pressure switch...

dude, please, no.


im using the STOCK LS ECU, i dont care what anyone says...

and WHAT THE **** DO U MEAN ABOUT THE REVVING?

what? that statement has less merit than **** on a stick... a d16 can be meant to rev 12K...its all in how its built

SO WHY CAN'T YOU INSTALL YOUR WIRES. YOU DAMN FACK

coil222

Why not just save yourself some trouble and run a damn vtec ECU?

The bit about high revving is referring to the 'trend' of new LSVTEC drivers going out and blowing their motors up by driving them like the new set of camshaft lobes allows the motor to spin to 9,000 RPM. Keep the revs under 8,000 or your looking at damaging your shortblock. If your motor is fully built you can rev to whatever your internals can handle, but I doubt this is the case because a built motor is quite expensive and you're cutting costs/corners by skimping on your ECU and Fuel management.

How do you know I'm not just another interweb homo spouting off my opinion?

My daily driver has been an LSVTEC for the past 3+ years and I've had no major mechanical issues by observing this one rule (ref. to the revving). My worst 'breakdown' was due to a faulty ignition coil.

Im sorry, I work on these things daily... you sir are a tool. In the interest of being a halfway good hearted individual, I hope your **** doesnt grenade on you... In the intrest of a tuner, you asked us for information, those of us who know things tried to get you to maybe rethink it a little and use a safer method, you assume you know more than we do... soooooo... have fun with that....

now that you tried searching, try learning how to properly search.

there are dozens of ls/vtec right ups in the archives.

Also try google.com for information.
