I have 6psi with t25 ... i have rsx-s injectors... here is my question... can i controll the injectors with the v-afc2 or can i just adjust the map.... oh yeah how well does the v-afc2 work with missing link? Thanks

Missing link and V-afc work separetly and will work fine.
V-afc is the worst method of controling fuel on turboed car. V-afc can add fuel with rpms, but it cant add fuel based on psi.

If you are short on cash,
You might want to look for used TSI injection unit. It can add fuel by psi and by rpm and it has 2 injectors that are adding fuel.
Used piece should cost about $200.00

Stupid question: What is a "missing link"???

Thanks in advance!

When you add a Turbo to your engine, The MAP Sensor (Manifold Absolute Pressure) which is designed to read Vacuum Pressure, will read Turbo Boost and throw a Check Engine Light. Missing Link prevents the Computer from determining the correct air flow and results in poor engine performance. The Missing Link intercepts the Boosted air flow before it hits the MAP Sensor. This fixes Check Engine Lights, Helps the Computer to Maintain Proper Air/Fuel Mixtures and provides smooth Vacuum to Boost Transitions. The Missing Link installs in 5 Minutes with common hand tools.

tuning the tsi injection unit i heard is hard and no shop here does it.... apexi v-afc 2 can do it by rpm and its fine... as long as it adds more fuel ... but you said missing link and v-afc 2 with 310cc is cool...?

i don't think safc and missing will work well on turbo car. if you are using safc hack method, the tuning has to be really precise, because safc needs to manipulate map sensor reading to adjust the fuel.

I will not recommend safc hack either, because it will advance your timing a lot when you lean the fuel out with rsx injectors.

^^^^how'd that go? how hard is it to tune with the v-afc...did you use the hack? xproductionz?

what HACK are you referring to... all i did was connect the vafc and went to my local tuner and bamn.. my a/f was tuned.. other than that you can tune it your self if you got a a/f gauge but that should only be a temporary thing... lol... not recommended

BoostedVik

you had missing link and v-afc... did you have any bigger injectors?

xproductionz

oh.. lol.. it was a custom turbo setup with type s injectors.. vafc2... and the missing link.. at the time dezods kit wasnt even out yet so i had really no option on the kit i could use.. SF was just making there kits available...

BoostedVik

sweet... you are one of the 1st to boost!!!?

i wouldnt say first.. im sure there were others out there that must have done it.. of course since they were already making missing links for our cars at the time.. lol

lol..If you know how to use a cell phone - you know how to play with tsi injector box...No special training needed what so ever....

re: bold text
Wrong, as someone mentioned - you can use it as a temp solution.
You need to understand that at 5000rpm you can either bee at 10psi or you could be at vacuum, but v-afc will continue dumping fuel to the engine. Not very good for spark plugs, o2 sensor and "general driving enjoyment" (engine will run like crap)

Please read this fine print:
Since you already have rsx-s injectors, then spending $200+ for v-afc, I cant concider this as a sound investment, where you can add another $100-some to by e-manege box and then have practicaly unlimited tuning capabilities...
