is this the ecu? safc install ? URGENT! - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

devonkyle77 · 06-15-2005, 08:06 PM

new to electronics, and i am working on installing this safc. i believe the ecu is the white box going vertical with the 10mm bolt in it. so i am assuming i just remove the 10mm bolt and the top of the white plastic casing and splice the correct wires. let me know if im wrong or right please. this is on s14 by the way, with ka

thanks and sorry for such a newbie question...

installing the SAFC and or setting the initial settings incorrectly can seriously F UCK your motor up...make sure you read the directions in both books and flip back and forth a few times to make sure you know what your doing...choose the wrong pin and you could jack it up as well...and make sure you solder the wires and do it right the first time..not black tape....asking where the ECU is on the car while installing the SAFC sounds like you may want to ask for some help first
good luck

devonkyle77 · 06-15-2005, 11:11 PM

other than making sure the wires are right (obviously) do i need to take any special precautions when working with the ecu?

g2ic02 · 06-16-2005, 09:34 AM

i am gonna agree...i don't recomend doing that job unless you are confident with your electrical skills. Your gonna have nothing but problems unless you do it perfect. But if you insist on doing it your self, good luck. Pick up a soldering iron, solder with flux, and some heatshrink to shrink over the individual connections.

TheSparo · 06-16-2005, 10:03 AM

disconnect battery?

sdtouge · 06-16-2005, 10:16 AM

i would say pay someone else to do it.

nismo2491 · 06-16-2005, 03:30 PM

for real man, if you need some help with this me, robbie, matt, john etc of MA240sx, should be able to help you. personally I'll install it for $30 which is pretty damn cheap...

mjjstang · 06-16-2005, 03:44 PM

yah dont do it yourself, because splicing wires is sooooo hard, and reading instructions is even harder. *sarcasm*

or take nismos offer, but make sure he explains it to you also. Remember that saying, Give a man a fish and you feed him for a day. Teach a man to fish and you feed him for a lifetime.

nismo2491 · 06-16-2005, 03:49 PM

splicing wires and such isn't nescessarily hard, but shorting out a wire because of one little mis-movement and consequently shorting out an entire ecu can be expensive...

iknowyoulike · 06-16-2005, 10:13 PM

listen to everyone mang....don't do it yourself if you don't know what your getting yourself into..especially if you can't even tell if that's your ecu or not....i'm not trying to be an asshole or anything too. seriously i'm not, check my post about how i fucked up my install...i did mines a couple of days ago and i finally got it to work like 15 mins ago. so if your unsure don't like others have said it can seriously fuck your motor up bad!! but incase you need the pinout guide i posted it in my thread!!!

***S14DB*** · 06-16-2005, 11:16 PM

What's an ECU? Is that like the EGR?

The reality is, if he doesn't know what an ECU looks like. He shouldn't be atempting the install.

nismo2491 · 06-17-2005, 02:53 AM

^agreed, I live maybe an hour from the guy, if that, which is why I offered to help...

pr240sx · 06-17-2005, 08:45 AM

First disconnect the battery
get a diagram, study it, read all the instructions on the manual and all SAFC installation threads for S14 all over the net.
Get a FSM, you will thank me later
Identify the wires, all of them, before doing anything, double check with both Apexi and FSM diagrams. Be sure to look at the diagrams correctly. Like other said, you can short your ECU at least.

Get some splices, connectors and electrical tape. Befoer cutting anything.. leave some wire as slack, just in case you need to reconnect it.

Be sure NOT to leave any exposed wire, reconnect the ECU (if you removed to connect the SAFC), double check, triple check and connect the battery.
Before starting the car, be sure to reset the SAFC, even it is brand new, check SAFC manual for this.
Then set up the safc for the correct setting for your car, do the sensor check on the safc and then start your car.
Verify idle speed. All corrections on the safc must be 0 if you have stock injectors. If you have changed to bigger injectors adjust them accordingly in the correction map before starting the car.

Good luck!!
