Safc And Vafc Air Fuel / Vanos - BMW Forum

kingsiang · 01-12-2005, 08:44 PM

hi guys, I was thinking of getting a Vafc II and/or SAFC II but i was curious if it will work on a BMW? has anyone tried it? any tutorials on it? and wonder if the VAFc will be able to control the VANOS? Thanks for looking.

Yes... they can be used... its only a few wires to connect... all it does is alter the singal that your mass air flow sensor sends to your ECU... it might do a few other things.. but I cant remember off of the top of my head... it doesnt change your vanos.. it cant.. and will have no effect on it.. unless you consider the inadvertant changing due to your air/fuel mixture being of a different blend because your air signal was tampered with.

Its a good tool.. and I've seen it been used very wisely to gain and get a lot of important information..

Good Luck,

Les

After further research that controller is specifically made for VTEC.. but not totally unuseable for us... trust me.. I've seen them...

VTEC uses a hi and low or central changing point between their cams... I'f I'm not mistaken here... our vanos systems use a tensioned chain that creates a smooth blend between a high and low cam for better performance out fo the cam at all throttle levels...

Just some more information...

If you find anything interesting.. please post it... I will probably end up getting on of these sometime...

Wow thanks for the reply... it was really helpfull. i somehow happend to remember vtecs and vanos are similiar technologies, and when i was shopping for some parts for my car i saw the VAFC and SAFC and RSM's from apexi. Then i thought the vafc's could alter opening time of the high cams... but guess i was wrong...

Im looking forward to anyone who knows how to install a SAFC into a e36 bmw... That would be a GREAT help to all the bimmer fans out here...

cause SAFCs are not too expensive about 200+ shipping

THANKS.

:wink

If I'm not mistaken.. they come with a model ready installation guild.. you should call and find out before you buy one.. but I'm sure each model has its own directions... or atleast in my mind it should.. due to the complexity of each differen make/model out there today.

Good Luck,... and if you find some more information.. please post it..here..

i believe so they will work on an e36 after a few research ahha

from site it states the mods available for the e36 bmw's so i suppose it will really work with it. But the cables and stuff... hmm i think it would be pretty hectic... will follow up if i find something...

If you tell me which wires it hooks up too.. I could probably tell you how hard it would be to wire up...

I wired my buds 350Z in about two hours... and that is some crazy japan wiring crap... so it cant but but so hard...

i was just wondering too... if a e-manage system will do well for a e36 m3. any thoughts? thanks.

97alpineM3 · 01-14-2005, 11:30 PM

What are you speaking of... are you talking about an electronic control system... mainly tuner wise?...

Just as the Safc?... I think if you use it to its limit... and understand what your doing.. it could help out a lot... along with a good software program.. such as the Jim C. Shark Injector.. you should tune her up rather nicely.

kingsiang · 01-14-2005, 11:40 PM

hmmm im not too sure which to go... simple SAFC with Jim C. Shark Injector or the full piggy back system... im a really confused man right now.

btw i thought Jim C. Shark Injector works with only obdII system. mine is a 1995 m3

pls helpppp

97alpineM3 · 01-14-2005, 11:44 PM

Ok... well since you have a 95... there are a few other options.. they are actual hard chips... not just a flash program for the system... you will probably get more gain too... but Turner Motor Sports has a good one.. along with AA Tuning.. and I think Dinan has one... a few other respectable tuners have hard chips for the OBD-I system which would match up rather nicely...

Les

kingsiang · 01-14-2005, 11:44 PM

oh ok my bad... never realized there are Jim C. Shark Injector 1995 m3 ones...

If i have Jim C. Shark Injector do i still need to chip the cpu?

im full noob sorry.

kingsiang · 01-14-2005, 11:46 PM

whats the difference between hard chip and flash chips? and why and how can u get a tune from AA after the chipping? i thought chip does the tuning already.

kingsiang · 01-14-2005, 11:48 PM

and whats the difference between the Jim C. Shark Injector and a hard chip... sorry for asking... im getting very confused here. complete noob.

ghead

97alpineM3 · 01-15-2005, 12:01 AM

Hard chip looks like a computer chip.. and is put on your ECU if I'm not mistaken... and the Shark Injector is a thing that plugs into your OBDII uplink.. or data port.. and is sorta downloaded onto the computer.. in a form of a flash program which just flashes the system or computer system with the new information.. I will get more information for you tomorrow...
