SAFC I Reset - help!

[mupkant]

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

oh btw safc is 2nd hand, so the chances are the settings were made for the pervious car.

some1 save me! please

ive read through it

cant find anything

can you recommend some settings i should change?

[strutto]

hang on...

[mupkant]

ah think ive found it

[mupkant]

ok it worked now

i got to the re-initalise factory settings menu and it worked.

the first time i tried it didnt.

thx anyway strutto

always a help

[strutto]

etc menu

initialise

This will set the SAFC back to factory defaults...

You WILL have to set the sensor type again before you can start the car... What car is it for?

Also the cylinders and throttle sensor type will need to be set again...

ok i set it to Hotwire 4

choose 'hotwire'

and keyed in "04" "04"

is that it?

[mupkant]

oh and for cyclinders i choose

6 and the arrow up

[mupkant]

when i change it to "04" "04" the cars rev starts droppin then the car turns off.

i figure '04' do to the table for my vechile. and i read the manual

"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 thats pretty much it... once you set hw4in and hw4out you might have to set the calculation to 1 to 1...

but that might only be on the SAFC2?

[strutto]

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...

[strutto]

after you set the hw4 in the sensor no, push to the right again and you will get the sensor calc screen... set this to 1 and 1 and all should be good.

cylinder and throttle settigs are good...

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

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

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.

[mupkant]

thx, the THR wire wasnt even connected!

got it connected and works fine now

when foot flat down reads 100% when right off 0%

looks good

ill take a look at voltages
