I did the v-afc hack on my car this weekend. My car drives 100% better, but now my car goes into limp mode everytime I hit boost. I was wondering if anybody could help me with the settings on the v-afc. Right now we just have basic -35 to -40 taken out across the board. I have not messed with the throttle correctin or any other functions.
My setup is
B16a2
Darton sleeves
JE pistons
Crower rods
ITR head
CTR cams
ITR intake manifold
JG throttle body
RC 440 injectors
DC fuel rail
Walboro 255 fuel pump
MSD boost a pump
V-AFC
AVC-R
Drag turbo kit (60-1)
Greddy type 24 intercooler
B+M oil cooler
Fluidyne radiator
Clutchmasters stage 4 and flywheel
Kaaz limited slip
SKunk 2 computer
Thermal 3" exhaust

Sorry for long list but I just want to give as much info as I can.
Thanks for any possible help.

 

how much boost?

 

running 8 right now. Wanting 10-12.

 

if you go over 10-11 you need a 3 bar map sensor

 

maybe you're running too rich or something? have you dyno and wideband tuned it yet?

 

THe only reason i'm using the v-afc hack is cause I haven't had the money or time for the dyno. Just trying to get a drivable 10 pounds till I can get it tuned. This is just going to get me thru the winter . I'll have a standalone and bigger injectors early next year.
I'm just trying to get a few base numbers from someone with a similar setup.
Thanks for the help.

 

Isn't the Skunk2 computer optimized for all motor applications? If so, the very aggressive timing of that computer would not be good at all with your turbo. When you say you are going into limp mode when you hit boost, do you mean your map is throwing a check engine light with any boost?

 

what is the CEL code? Are you sure its not something else?

3bar sensor and a standalone...you cant run a 3bar on a honda ecu without totalliy messing up the fuel.

blueturbo, are you sure you have the vafc adjusted to -40 on all the maps? Remember, there are both wide and low throttle, both on and off vtec. Just something to check. Its easy to miss the different maps if your new at messing with the vafc.

 

I'm not sure if the skunk computer is for n/a cars.
I'm having a problem wiyh it right now . I can't get the check engine light to go of even after I reset the computer. The last code I got of of it was an o2 sensor code.
I will be playing with the car more this weekend and will try to pull the codes then.
I just found the post of setting the hack to -40,I'll will try that this weekend also.
I'm more curious about the LO HI settings. Should they be set at 98 99% or 71 72% ?.
Thanks for the replies so far. I'm still trying to learn about this turbo stuff.

 

If your maps are the same for HI and LO throttle then it won't matter where you set it at (98 99% or 71 72%)
