440cc is gonna be on the big side for your application

for a 7a, somthing in the 360cc range should be more than adequate

Noo..thats how your going to blow your engine. You cant add fuel with the SAFC, only take it away. The best thing you can do with this is add a fuel pressure regulator to add fuel, then use the SAFC to tune it properly.

In addition, the stock fuel system of a 7a of 5s isnt enough for a turbo. So the injectors and a new fuel pump is necessary. The SAFC is not a substitute for the proper parts.

erik, i believe you have that backwards.
its remove fuel = advanceing timing
adding fuel = retarding timing

so what size is stock ?

you think i can get away with 6-8 psi whith 305cc??

Thats not his concern tho the timing, he wants to add fuel for his turbo setup? I'm guessing and the SAFC alone isnt the way to go and I'm afraid he's going to grenade his engine.

k car runs ok i think. but need to drive more to tell if theres a difference.
when i turn on the car all the knobs are green, when i hit like 1500 rpm
the first knob(800 rpm) turns orange then the gets brighter red as rpm
rises. Now i don't know any body thats had one of these so i don't know
if thats normal? but if i had made this i would of had each knob turn
red as the rpm reaches that setting. maybe its suppose to do that?
maybe not? .........help

Yes, A5 or A18, A18 is a red wire right next to a white wire.

[southwest2118]
