S-AFC Dec.Air Setup

[rs73]

Hi...

Anyone here used S-AFC Deceleration Air setup?

If I used mine especially when engine is cold, car won't idle nicely and will eventually stall.

According to Apexi S-AFC Manual:

Throttle Setting: While engine is cold, & transmission is neutral, set the unit to a point LOWER than the throttle position Ne2 point can control (In this case, my Ne2 is 2000rpm)

Ne1-Ne2 Setting: While the engine is cold, & transmission in neutral, set the unit to a point LOWER than the air flow % usage a value that the Ne1/Ne2 engine RPM can control.

thx.

had the same problem when i set mine!

u aint got a BOV have u? u dont need to set that function

i c.... I got factory BOV which should be plum back type.

so that Dec-Air function only for cars fitted with aftermarket BOV which vents to the atmosphere?

What abt yours? You got venting BOV right? n still didn't work? Just out of curiousity if anyone managed to set that one up succesfully...

Yep mine Blitz atmo 1, and setting the dec-air did nuttin!

Its a bit better now since i tightened up everything, but still stalls if i acelerate then brake quickly

I tried mine at Thr Setting 4%

then Ne1 at 1.5% & Ne2 = 4.0%

The reason is at 2000rpm (my Ne2 setting) my throttle position is at around 6% when engine is cold. Then my Afl usage (see in the monitoring mode) is around 4.2% at 2000rpm and around 2% at 1000rpm.

It seems to me that when I accelerate it bogs down a little bit from 2000rpm onwards but then it's fine, on decelerating it doesn't seem to stall but again I dont have venting BOV so maybe that's why.
