dang.. took us about 4 hours but we finally got it done... dont trust what everyone else says u need.. u dont need the ECU from an EX to convert over.. heres what u will need if you want to avoid getting an ECU from an EX and reflashing ur key
EX vtec head with solenoid
ex head gasket
and a vafc2
basically if you never have done a head swap before i highly suggest u take it to a shop to do it. we ran into i hiccup after completion cause i had some air bubbles in the coolant but we took care of that in about 10 minutes.. make sure u disconnect the battery before doing the the vafc install
and heres a picture of the cover taken off
so here is what the dx head looks like when its off
heres a picture of the ex head.. notice the hanging blue wire.. thats the vtec wire and solenoid...
heres the vafc2 controller.. this is the only way to bypass getting an ECU from an EX and getting your key reflashed
now heres the trick to wiring your ecu.. solder everything and no crimping.. i got a gas powered one so i dont have to worry about running extension cords
(EDITED 8/21/04)
now while wiring the vafc2...
first tape off or cap the blue VTM wire cause u will not be using that... also tape off or cap the purple VTEC wire cause u will not be using that either (the DX/LX does not come with a VTEC solenoid signal from the ECU).... also tape the orange wire cause there is no VTC cam signal.. and for other people that are also running the VAFC2 on there EX's we do have a TDC wire on our cars... it would be on pin 26 on the first harness to the left... then follow the installation instructions according to the vafc2 manual using diagram H7-a and dont worry about the other DIY mentioned in another topic thats says to buy a diode.. dont need it... now all u gotta do is finish up ur head install.. as soon as thats done.. remember that blue wire hanging from the EX head.. well cut off the clip
and hard wire it (see the light green wire) from the engine bay into the car next to the ECU... then solder that wire to the pink wire from the vafc... almost there
clean up all ur wires and finish up anything under the hood... fill back ur oil.... add more antifreeze..and now ur car looks pretty much the same when u first started..
haha with the exception of the vtec solenoid and wire.. PLEASE NOTE that if u have had a DX intake then the place where it mounts has to be moved cause that bracket where it used to mount is now replaced with the vtec solenoid..
do the start up proceedures according to what the manual says for the vafc before starting the car... now as for me when i was done.. it took a few minutes before the car actually started... once it finally ran it idled pretty bad and fluctuated... then after a good 2 or 3 minutes the car ran perfectly fine.. my friend says the ecu is just adjusting to the new things we put on there... drove it around for an hour and set my vafc to kick the vtec from
Lo-->Hi at 4700
Hi-->Lo at 4000
just basic settings to get me started but its not even tuned yet and can feel the car pulling alot more when the vtec kicks in
hope this helps

Holy Mackerel!! Does this really work? Please update after a few days and let us know of any issues or probs encountered, etc. What do others think of this truly amazing aftermarket engineering? Is the convertion worth the cost if done by a shop? A used EX head shouldn't cost that much and it could be ported at same time. Hmmmm.
well.. just got home from work..after we finished working on the car i had to get ready for work.. so drove to work.. now i am home and so far no problems.. works great..i got my used head complete for $200.. plus i was going to buy a SAFC but then i decided to just go ahead and buy the VAFC2 and go ahead with the swap.. gasket costed me $35 and labor was free of course cuz me and my friends did it.. just bought them dinner and some beers

It would deffinitly be beneficial if you could keep a daily log for the next couple of weeks letting us know how this went. I'm not honda literate yet, but does the vtec solenoid get it's oil from ports in the head, or is there an oil line/return line, you have to run to the solenoid?

Thanks.
it get oil from the return line in the ports.. theres no additonal line to wire or anything like that..
my car is like the sleeper type only a kaminari spoiler. But Vortech turbo in the engine bay with blow off valve aftermarket DC Header with a Magnaflow catback exhaust, NOS and more
