Hi guys,

Just installed SAFC I today by mechanics, dunno if they installed it correctly, since when i go into 'Monitor' --> '4 Channels' its shows the revs go up as i accerlate, also the air flow and correc. BUT NOT 'Trottle'

Throttle is always at 0% is this correct?

The main issue here is i want to reset the settings completely or change everything to value 0?

so that my car doesnt act so spastic, when i accerlate,

At the moment when i acceralte-moving to certain RPM's the car fully jerks (reminds me wen i first learnt manual) and sometimes the car seems like it will stall when dropping its REV's

Very dicculty to drive

Can some please help

where should i set the values to 0.

and dont say get it DYNOED as i will not untill i have an exhaust!!!

thanks

"If. Sensor type is 'Hotwire' ...............

"if Sensor type is Pressure'...........

nothing beside it, looks like a bad pdf scan? a blur line in the pdf.

page 28 of the pdf

Yeah.. make sure you get the sensor type correct. I remember dicking around with that setting at one point. If its incorrect basically your engine check light will stay on and wont start. If you do a search on here you should be able to find out the base settings to at least be able to drive around until you get it dyno tuned.

THR should visible on the screen (% to full floor accelerator). Even if its just in ACC mode (e.g. not running), you should be able to press your foot to the floor and see the % THR change. If its not changing then its possible your mechanic forgot to connect the correct line to the ECU.

I've got an S-AFC I as well, so if you want the base settings and still having trouble PM me and I'll go turn my car on :P

omg Throttle % does not rise as i accerlate, only the airflow % & rev %

guess mechanic f*** the wiring? =

ill pop the ecu out later and take a look.

yes please with standard settings, just in case i left anything out

dont do it with the engine running...  just turn the key on until the reds come on in the dash...  perform the settings... turn the car off and then start it...

hehe thx,

i remember when i went to pick up my car, my hands got itchy so i played around with the settings, but was only meant to check the Monitors menu at the red lights.

somehow went to ETC and selected a wrong sensor

Revs dropped and my car stalled right in a Hwy (80 kph) road. :)

had to jump start it, as the battery was raped when trying to start it 20 times.

When connecting my SAFC-I this week we noticed the manual doesn't actually tell you to connect the throttle wire. I had the SAFC-II manual as well and had to use that to wire the throttle. For some reason it only reads 85.8% foot flat to the floor though.

mupkant: went out to check my SAFC(1).. sensor type should be definitely "hotwire" (referring to the AFM I think). Check your voltages in "sensor check" while the engine is off. Sensor1: should be reading a reasonable value (around 1v or something). Sensor2: should be reading around 0v (mine was fluctuating between 0 - 0.1v). Again, THR voltage should increase as you put foot to the floor.

Definitely sounds like your problem is the lack of the THR line.. check the loom near your ECU to see whether its wired up.

neil:se -> go into the "sensor check" mode off "etc" and check the voltages.. mine at 100% THR (foot about 90% to floor) is about 4.35v. I'd check you're connections, maybe its dropping a bit of voltage due to dodgy solder job, etc. It could make a difference to overall effectiveness if the THR is out a bit.

      R32 GTR Limp Mode?

      R32 HICAS, so long as the CU is not itself faulty, is easy to keep working enough for the PS. Just unplug the smaller of the two loom plugs, on the CU, like I have already said about 4000 times on this forum. This works with all the stock hardware, or with a lock bar, or with a complete removal. I know, because I have done all of them. OK, actually, I never put a lock bar on because why would you put a lock bar on when you can get rid of the whole lot, including the stupid tie rod ends?

      Join the NorCal facebook group btw, but if you can confirm it is HICAS I would install a lock bar and do the work to keep the HICAS control unit happy despite the hardware not functioning. The HICAS control unit is also responsible for speed sensitive power steering so if it's unhappy you'll get failsafe/heavy power steering. A standalone can control that power steering solenoid valve but sometimes it's just easier to stick with the factory setup. Tomei makes a little electronic module that you can install to fool the control unit. I would probably go through the effort to not use a scotch-lok and build a harness so I don't have to chop up the OEM harness. Where you could source those connectors and pins I wouldn't know at the moment though.

      Pops when backing off throttle, rough-ish sound through rev range.

      Oh, another question comes to mind though. What sort of shitty fuel are you feeding it. Mine, a turbo, has to be fed 98RON, so it doesn't ping itself to death. 98 in Oz is good, dense fuel with minimal oxygenated compounds. Meaning that the energy density is high, and if the O2 trim is working, you will get more MPG than with a lesser fuel. If you're using some sort of piss poor E10 blend with some other MBTE or other oxygenated additions, that could explain using more per mile.

      I have no idea where the thump is coming from, it sounds like its from behind me but im not exactly sure. And it was the HICAS light that came on.   I think a complete delete is the route im going to go. Probably going to pick up the kit within the next month and get it installed. HICAS is just going to end up being a headache if I keep it.    Thanks you.

      Steps to DIY sanding car back ready for respray....

      By silviaz · Posted

      Just putting this here for reference for other beginners. Similar to what I said above.  I learnt if you have a few dents that are fairly close to each other (within a couple of inches maybe 2-4 inches?) Use filler across them all and sand it all at once with the long block as opposed to fixing them seperately.  Will make life MUCH easier because you won't get stuck in the cycle that I did. I think doing it seperately there is some overlap (mean your whole repair zone might cover near the area of the other dent) and you start sanding near the other dent making a low spot.
