turbo feul injection

hey, i was just wondering if i could just pul a safc off of ebay for around 100 bucks and then tune my air/feul stuff with it on my 440cc injectors that will need to inject more feul for the turbo setup. any help is welcome. thanks

IMHO safc and vafc's are trash on hondas. Since we dont have maf sensors like most cars, we only have map sensors, yes its wired in differently but I still don't believe they work at all. Why? Because just think, the ecu is looking to give the correct amount of fuel to the motor that it thinks it needs. When you up the fuel setting with the safc the ecu is going to see all this extra fuel coming in and be like WTF? So its going to drop the pulse rate to stop giving so much fuel. I could go way deeper into this but its not worth it since most of everyone on here has no idea what im talking about.

I think I know what you're talking about. And yes, most likely a CEL would be thrown and something would go terribly wrong.

i dont want to do the whole chip the ecu thing. because every place that does it says it must be obd-1. i just want to run the 440cc injectors for my turbo and be able to not wory about a bad air/feul mixture and cuase my motor to blow. like everyone has said on here tuning is the key but how or what should i use for this. and i dont have money for a Zdyne ecu either tho i would love that setup in my car.

you probly already know bit just in case you dident the safc puts out for fuel bacause its telling the ecu its at a highewr rpm therefor it will need for feul. just in case you dident know that. but i see what you mean by the ecu fixing the problem and going back to normal. smart computer they are

Turboedit or Crome

wow. i dont even have a clue what those are. please help a noob out on this. is there somewhere that does it for you. there was a guy on ebay that said he would make a chip for people and edit to whatever they need. and there was another guy on the HMT forum that said he could do it but they both want obd-1 conversions done before the chipping process. i dont know what to do anymore

Those are the ecu editing software programs available (I believe for free) on the internet. I haven't really considered turboing my engine to that extent so I never really checked it out. But those programs allow you to optimize tunablity in OBD0 cars.

what? where the hell are you getting that idea?

i read it on the web page or one of the google search things i did. but then again the web page did have spelling errors so it probly wasent the official web page. you think in the instruction manual that they would try to speel things right.

yea, i guess they'd want to spell things right too.

haha. i tried to edit that write after i posted it up. i noticed as i clicked the submit button. i had a laugh to.

shit i know this thread is old but i was just thinking, why not disable the ECU and then you can run your aftermarket injectors without the ecu fuckin with the fuel/air....

If you disable your ECU your car will not operate... unless you install a carburetor or something... :lol:

Wow, bypass the ECU?? Thats a first. Even carbed Hondas run with ECUs so I don't know how you can think about disabling the ECU especially with a turbo setup.

Ok, there is too much misinformation in this thread.
-VAFC's don't make your computer think it's at a different RPM. It alters the map sensor voltage, so that the computer thinks the air is denser (more air coming in) and alters the fuel amount to accomodate that. V/Safc's are TRASH. Do NOT use them. When you increase fuel with a vafc, you are actually advancing timing and vice versa for decreasing fuel. That's the opposite of what you want for a turbo setup. You want to retard the timing.
-You DON'T need to convert to OBD1 to tune. Essentially, the ONLY difference between OBD0 and OBD1 is the o2 sensor. All other sensors are the same.
-There is plenty of OBD0 software available for you to tune your car with: Turboedit, BRE
-Go to PGMFI.org. Go to their forums and read up and teach yourself something. You can download the tuning softward there. The software is not that difficult to operate and you can learn to tune your own car in no time.
