lol whatever, thats why i am researching the use of an apexi safc, let me give you the non abbriviated term apexi Super Air Fuel Controller, in other words with this i can change the fuel mixtures so that the car will run the same as or better than stock(oh with the aid of my wideband o2 sensor). i am adressing both fuel AND boost issues here, i know not to just turn up the boost on these cars. oh i remember a certain someone that might have thought the higher elevation you are at the better your car runs. can't remeber who though. lol.

maybe its super air flow controller, lol can't remember but anyways i can control all fuel settings for the car for upped boost and even adjust for bigger injectors, just have to know how and have the proper tuning tools(wideband)

and just so you know a wideband o2 sensor is the most accurate(much more than stock) way of reading of how rich or lean your engine is running, its a seperate system from the ecu, and uses a seperate wideband oxygen sensor."




Ok, dude all im saying is why not spend like 500bucks for a chip which contols everything, timing,boost, and air fuel. And then run a boost controoler on top of that. If your this smart then go ahead and do it. But I think dave was running stuff similiar to that and his engine blew. Not because of his fault but because of fuel shortage. A chip would have taken care of that.

 

no a better fuel pump connection would have fixed that. it shorted out and cut fuel.

 

im not even talking about runing a chip at all, with a boost controller, fuel computer, and even a boost dependant ignition retard system you would have all the reliability you would get with a chip, as your still using the stock chip just giving it extra of what it needs when it needs it.

dave, what do you think of the HKS boost controller(the nicer one), i think it has the ability to "learn" your turbos flow characteristics and adjust wastgate operations to allow for better spool time, im not sure of this though. does the profec do this(looks like it might), also were you running anything to control ignition timing? like a retardation system of sorts? msd has some systems out that depending on boost levels you can adjust ignition, ill look into them some more.

i figure it this way;

apexi safc(2ng gen silver, blue gauges) $150-$200(maybe less now)
Profec or similar boost controller $200-300
Boost ignition retard iv seen easy ones for about $75 up to $300 for fully programmable spark, ignition, and other cool stuff.

so with that list you should be able to control all vital aspects of your engine, increase boost, adjust for varried sized injectors, and fine tune to produce more power, but this is really for someone who likes to be in control, i don't like computers dictating EVERY setting and not allowing me to alter them. this could work if someone wants to try, but its all preference, its about the same cost as a chip with much more upgradability options, and you have control.

in the end i will probibly just go with a giac chip because i want more power but mainly this car is not supposed to be a project, its a daily drive to get me from one place to another, a wire comes loose and the whole system has the potential to cause some damage to my car, not with a chip however(well its waranteed then). so yeah i think im probibly going to go do a chip since i need this car and im not building a car with the intentions of max power, just a little more fun to drive.

if anyone wants to try this setup out i would be more than willing to help, i know it will work, i know i could tune it very well, and i know it would gain you more power, so if anyone wants to try the send me a pm and i will surely help.

 

nope. just get a chip. its less expensive and 100000000000 times more reliable.

 

haha you start out your post like this....

"im not even talking about runing a chip at all"



and end like this....


"in the end i will probibly just go with a giac chip"

 

yeah, i realized i need a reliable car and not another race car for a change, lol i convinced myself to go to a chip. gotta pay some bills first, then its boost gauge, 710n, chip, ecs n75; in that order, oh maybe an exhuast in there somewhere.

 

Why arent you running a bov??, you said they work well.

 

they do.

 

i know, on certain setups. I want to run one but i think im gona do some other stuff first.

 

Okay lets get something straight. BOV's do not make your car run rich under wot. They do once you shift. Its because they fall after the Mass air sensor and the reading the sensor gives is incorrect. They do not affect driving around, only under deceleartion aka "decel fuel cut."

Secondly, a chip is good for cars with stock turbos and bolt on mods. You upgrade that turbo, change the fuel pump, injectors, etc, your 93 octane revo chip is not going to perform right. Chips work good with limited mods, but you need user definable parameters when you start getting into big mods. Hence the afc. Thats what our friend above was getting at.

That said I think the afc is a piece of garbage. If you are going to go that route (user definable settings) and you have spent the money on a new turbo, injectors, etc then man up and buy a stand alone. I would not want to spend all that money on mods and then trust a piggy back system to control everything. Especially with obd2 computers...they tend to learn and try to correct to stock. Its basically pulling a pin on a grenade and having no idea how long the fuse is...

Im aware that some mfg'ers of turbo upgrades offer software. That is all well and good. I still would not trust anyone to my tuning needs when it comes to upgarded turbos. The average chip will not cover everything you need when you start getting into serious mods or worse yet engine work...but I will not even go there.
