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.

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.

      My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.

      Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).

      Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers

      Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.
