so yeah...i got an safc2 and i installed it for my car stalling problem due to the bov. I havent done any other fuel tuning because i havent got my wideband yet. So I have read a lot of threads and read the manual.

So from the threads, basically they said to adjust the throttle point to 1.0 and ne1 to 4 and ne2 to 5. and Ne1 to rpm 1000 and Ne2 to rpm 2000 and Ne3 to rpm 3000. and start the car, and start adjusting the Ne1 from 4 until the car starts jerking and stalls, the I should start adjust it more very slowly until the car idles smooth. and adjust the Ne2 to 1 more than the Ne1 point.

Here is my first question. For the Ne point rpm, Ne3 doesnt go up to 3000. I think mine goes up to 2600 or 2800, I cant remember. and It does help the car stay away from stalling, but when the car comes to a stop, I throw it to neutral, the rpm sometimes goes down to 500 to 400 and comes to 1100 and goes back to 800-900. Is it normal?
And after I adjusted it as the threads say, the next morning I start the car, the car doesnt idle smooth when its cold. It jerks a lot for a while. Is it normal?

On the users manual says, I start the car when its cold. and hold the throttle to 1000 rpm for Ne1 % and hold the throttle to 1600 rpm to set the Ne2 %. And set the Ne1 rpm to 1000 and Ne2 to 1600.

My question is when the car is cold, the idling is about 1900-2000 or for sure more than 1000 rpm. How can I hold the rpm to 1000 when the car is cold???

the writer said set Ne2 at 3000rpm. Mine doesnt go up to 3000rpm. My Ne3 doesnt even go up to 3000 rpm. but with that method, I tried with Ne1 to 1000 rpm and Ne2 to 2000 rpm. The car started jerking at Ne1 3.6% so I set it at 3.7% and Ne2 to 4.7%. As I said, the stalling issue became better, but when I throw to neutral at a stop, the rpm goes down to 400-500 and goes back up to 1100 and go back to 800. And the next morning I started the car, the car was jerking like hell again. I had to hold the throttle to make it idle smoother.

Might be something else, what bov do you have? Tried adjusting it yet and checked for vacuum leaks?
