WTB safc 1 or 2

[my240nissan]

anyone have one around here?

[99_civic_si]

is it for a map based car of maf based? if it’s map based, I got a gadget that gets the job done very well. Just kinda a pain in the balls to program.

[my240nissan]

no its maf

[woz]

i have the 1st gen one witht he dials, $100

[my240nissan]

what is the difference other than display between the I and the II?

[my240nissan]

can I see a pic?

[Whiteesil80]

my240nissan no offense dude but do you ever buy anything?

[my240nissan]

you never got back to me on the camber plates. I said I would drive to syracuse as soon as you said the word. not to be rude but when someone tells me where and when I try to be there as soon as possible

[my240nissan]

if the safcI will do the same thin as the II ill take it tomorrrow

BS, you flaked on me like 3 times, u said u would be there so i went home and was there. and you never showed.

[my240nissan]

well I apoligize for that I am not going to go back and foruth like some girls I was wrong. will the safc you have do the same things as the safcII? can I arrange something to pick it up?

[Whiteesil80]

thats also BS…those camber plates were all yours but you asked me about buying my interior and i gave you a price and that was the last i heard from you…but now Originalsin paid for the camber plates (BTW they are getting shipped either tomorrow or wens) and the kid i just bought that corbeau seat off of was also waiting for you. so you just seem like a guy thats just interested but doesn’t really have the money or want to spend the money. sorry

good luck with findin a safc though

the safc i have is the 1st gen one with the dials. there is no screen. it just allows you to adjust fuel +/-30. its much more user friendly but most people think they need the extra adjustment when 75% either wont use it or will use it without knowing exactly what they are doing.

what about the other shit? i still have that bumper laying around

[my240nissan]

I am tryin to finish my turbo setup right now do you think that will work on low boost 10psi max?

[woz]

what maf are you running and what turbo?

[my240nissan]

an n60 for now

[woz]

yea it should work fine

[my240nissan]

sorry n60 with t3/t4 and 550cc injectors. do you think I need a rom tune as well?

I got tired of typing this repeatedly on discussion boards, so I decided to add it here.

If you don’t know what a Piggy Back controller is, read about it first.

Piggy Back controllers allow stock ECUs to do things that they normally can’t do, like run larger injectors or deal with boost. Remember that piggyback controllers work by altering sensor signals before they get to the ECU.

Most of the time, the primary signal being messed with is the Map Sensor. This is critically important in a Speed Density car. The Map Sensor is used by the ECU to guess how much air is going into the car, and therefore how much fuel to supply in order to match airflow. When you “lean” out a car with an AFC, you are simply decreasing the Map Sensor signal - the ECU responds to the decrease in manifold pressure by supplying less fuel. When you “richen” a car with an AFC, you are simply increasing the Map Sensor signal - the ECU responds to the increase in manifold pressure by supplying less fuel.

The change in fueling happens for a reason: if you look at a fuel table, Map Sensor values correspond with columns. When you increase or decrease the signal from the Map Sensor, you are simply making the ECU use a different column than it originally would have used. (see Understanding Maps if you need some help understanding reading Fuel and Ign tables)

But wait, isn’t the Map Sensor used for determining ignition requirements too? When you “lean” out a car with a Piggy Back, you also in all likelyhood advanced timing. When you “richen” a car with a Piggy Back, you also in all likelyhood retarded timing. Look at trends horizontally (as MAP changes) in an ignition table, and you will see why this happens. This helps explain why so many boosted cars running on the “AFC hack” have issues due to excessive ignition advance.

The bottom line: Piggy Back Controllers suck because you cannot independently adjust fuel and ignition. Any changes to fueling will produce a change in ignition too, and often this is undesirable.

thanks for the info but I am confused I see people doing things different but I want to be sure I get the right things before I spend 1000+ on an ems
