set both hi and low throttle to these specs:

1000: -40
2000: -38
3000: -36
4000: -35
5000: -35
6000: -35
7000: -35
8000: -35
9000: -30 <-- just in case you over rev

this should get you around town boosting under 7psi. Where are you tuning your car?

i just tried to set the fuel curve... im sorry im not familar with the system and i cant figure it out. additonally the system did not come with a manual so if you could please tell me how to get to the proper setting it would be appricated.
i tried to drive around the block with just the setting at -30 (i went into setting then narr. thr. and set it to -30) and the car cannot go above 2,000 rpm's in first gear... is that normal?
thanks again

hmm..thats not normal at all. Do you have all the base settings right such as cylinder set to 4 and the arrow pointing towards the top right and sensors set to pressure and 6 in and 6 out? Plus are you going to run the hack or are you throwing in the fmu and check valves in there for the inlinepro fuel setup? If you are going to use the inlinepro fuel setup you do have to start with -30.

i do have the base settings right. cylinder is at 4 with arrow in the right direction... i also have 6in and 6out..... i have an fmu its the 12:1 that comes with the drag kit.... im only using -30 because i called inline pro and thats what they told me to do. it didnt work very well so i was wondering what you guys thought about it, i.e. ive already called them 4x today. also i dont know how to get to those settings for rpm range and the fuel curve that you told me about previously, could you walk me through that? my check engine light just went off so i dont know maybe its my 440cc injectors i put in; maybe i did it wrong but i double checked everything?
thanks for the help sorry for the book
thank you

is there a way to know if i didnt hook up the injectors right. i took my time and double checked everything... the car is not leaking fuel and it starts up..... it will run just not very smoothly.... im wondering if this could possibly be the problem?

Ditch the fmu if u do the afc hack!!!!! you are running hella rich. Better check your plugs they are probably fouled.

For the afc hack all u need is:
afc
440 injectors
no check valves, no FMU


id say start at -38 across the board and richen it up top.

the only things i have done to the afc were these... narr. thr. -30 all the way across the board from 1000rpm to 9000. additionally i made the sensor type 6in 6out, i punched in 4cyl. and arrow up and to the right corner. im not sure what else to enter? additionally im not familar with the vafc so if somebody could walk me through the process and tell me what exactly to do (entering the text into the computer) that would be great.
thanks alot

you would need atleast an 8:1 fmu and an upgraded intank or inline fuel pump and you can use the safc to fine tune it.
