Default vafc II or fuel pressure regulator

I am working on a d16 turbo project. 14 lbs of boost... ihave a vafc II and a 12:1 fuel pressure regulator, do i need to use both or will the vafc II suffice? p.s. i will be seeking a pro tuner to install and tune the vafcII.... thanx!

Word.

Or...i would run a standalone unit such as AEM EMS. Hondata s300 is sweet too.

Whichever you choose, I wouldnt stick w/ that piggyback stuff if you're running 14lbs.

Get rid of that FMU!

stand alones have more room for correctong itself in a case where you go and the baro and map and stuff changes in your engine. the stand alone, aem, s300 sees the change and makes the neccessary changes in the fuel trim to keep it at the air/fuel it was tuned. with the vafc its just a fuel controller and doesnt have the options like a stand alone.


but me a use crome. its cheap and easy to tune. just see what your tuner suggests and get that system so he can tune your car properly.

chipped ecu's are junk, go with hondata s2 or 300 and get it tuned.

Wow, your an idiot. Hondata does the same thing as crome, uberdata, etc . Only difference is the actual software is better than the two, although crome is a really good system. Both systems "chip" the ecu.

VAFC can be used but I highly recomend getting a system like crome, hondata, netptune to tune the car. All those systems can change ignition timing where as with a VAFC you cannot. For very low boost applications you can probally get away with using a AFC, but later when timing really matters in keeping detonation at bay you will need a better program.

If you do decide to go with the AFC make sure to buy some larger injectors. The stock 240cc injectors won't do much for you. A high flow fuel pump would also be a good part to buy.

Also if you don't know what a standalone is I would suggest reading up alot more about boosting. Check the FI forum on here and Turbod16.com. Both have tons of good info.

No your still sodering in parts as you would do the same with crome, uber, etc. Crome uses chips that you can take out (or you can use a ostrich which is more like hondata). Both have to modify the ecu and run the same way. If you dont beleive me look at the link on how to install hondata on a ecu.

https://honda-tech.com/zerothread?id=1348457 Oh look step 11, what is that you soder into your ecu, thats not a chip is it?

Go search for how to chip your ecu for crome, uber, etc and its the same process. Again, stop spreading false information if you don't know what your talking about (have you ever installed either system, used either system, seen either system?). Both do the same thing, one just has better software than the other.

just because you soder some wires, does not make it the same. hondata is a piggyback system with alot more features than some bs crome, like a 2 step.
people like you like crome because you only have a couple bolt ons and will probably never make more than 180whp.

You have just proved that you have no idea what your talking about. You don't soder any wires to chip an ecu with crome, uber, etc. Yeah you can soder wires to datalog but its not needed. And you must have never used crome because they have alot more features than just a 2-step. You just making yourself look more ignorant by each post.

Piggyback systems are controllers like AFC, emanages, etc. they all manipulate the stock sensors so the ecu does not really know whats going on. Programs like hondata and crome are eprom editors.

Again I never said crome was better than hondata, I just said chipping your ecu is not "junk" (and by installing hondata you do "chip the ecu). Hondata is a very good system, but at the same time so is crome pro. To each there own I could care less which system people run, I just dont want ignorant people spreading false information in threads, like yourself.

I'm done jacking this thread up trying to prove you don't know what your talking about. You have proved it for me. Don't bother responding to me in this thread becuase im not wasting anymore of my time or bandwidth on this site to reply to you. Your wrong so just man up and accept it.

You're a f*cking moron, and your user rating (%) clearly shows this. Get the f*ck off Honda-Tech, because you have no idea what you're talking about.

Wow. Your comeback reflects your intelligence level, that's for sure. If you were to ever travel to this area of TN, you wouldn't be so quick to stereotype...guaranteed. Not that I need to justify your stupidity, but I live in one of the wealthiest/best educated counties per capita in the nation. And, I only live here because I got a damn good job offer from a prestigious development firm here...I'm originally from Chicago. Good job at steretyping TN and me, though, and making yourself look even more short-bus than you already have

To the OP: 14 psi may be a little much for a stock motor to handle in the long run, even with a good tune. Go ahead and get your ECU socketed/chipped and have a good tuner tune it with Uberdata or Crome. Hondata is also an option, albeit more $. A full standalone such as AEM EMS or something like that isn't necessary unless this is a *****-out racecar, IMO. I personally use Crome to tune my car, and I love it. Most importantly, don't listen to SiRek4. He doesn't know his *** from a hole in the ground. Uberdata/Crome/Hondata are NOT piggybacks...they are fully-functional tuning software that can be used to FULLY REPLACE your ECU's stock fuel/timing maps. They can also read/measure/tune/account for anything else under the sun that you would need it for, right down to advanced things such as individual cylinder fuel trim, etc. Hope this helps.

if stock fuel pres is 43 with a 12/ 1 fmu your asking for 211psi fuel press, at 14 lbs boost fmu's arent really safe above aboout 6 psi...

this it what i meant about 15 year old exhaust tuners rollin on dubs..... didnt want to start an all out battle. i enjoy the intelligence on the page though! buy the way this isnt myspace!!!
just so you guys know the details, this is a low budget boost project. i plan to daily drive and hopefully can tune for the street and the track!

the low end consists of eagle h-beam rods, stock crank with steel girdle (since my knife edged crank got warped???),king bearings, steel head gasket, concave turbo pistons (which were cheap and hopefully dont burn up!)...

top end primarily stock except for gasket match port and polish and aem timing gear. for now i have injectors out of a 2.1 accord, stock fuel pump into an e2000 in line pump.

power transfer with stage 3 clutch and l.s.d.

and finally a 12:1 fmu and vafc II for programing so far!

wastegate set at 1 bar which is more boost than me and my friends have done before, so i will be seekinf pro for timing and programming!

blowing the car up is not an issue... but not running or burning up is!
