I was installing the SAFC 2 on my car this morning.

turned on the ignition, blue screen poped up, did the initial setting, tried to start the car, the engine turned but won't start.

The AFC2 is second hand, I re-set to the factory setting and tried all the function, but the car just won't start.

I checked all the wire connection, they seem alright. so I really don't know why.......

any idea?

any help will be much appreciated.

by initial setting do you mean that you set the sensor type to Hotwire, Sensor No to 4 In and 4 Out, and Sensor Cal to 1 In and 1 Out. also the Car Select to 6 cylinder and the throttle arrow pointing up.

the other thing that come to mind is the two ground wires, did you get them around the right way i.e brown wire closest the ecu and black wire further back.

if you go into the etc. menu and go sensor check, does anything look out of the ordinary.

I checked with the wires already, it had been connected correctly according to the APEXI installation manual.

QWK32, yes I did all the initial setting like you said and after that the enigne won't start.

when I pulled the plug and re-connected the AFM signal wire back together like factory setting, car started and everything was back to normal.

so.................I still have no idea, is my AFC faulty?

but I can see the blue screen and all function seems alright.

Yeah too easy mate, the settings aren't that hard to figure out. i just find that 9 times out of 10 SAFC issues are in the setup. I know you've said you checked the wiring, but something else it could be is if you have got the SAFC Air Flow Meter In and Out around the wrong way?

If that is right then as you said, you possibly have a busted unit. I don't know if it would be worth getting someone to check it out to confirm if it is dead or not.

checked with all the wires and connection, everything seems fine.

It seems like there is no AF signal output from AFC.........

does anyone know how to test it?

You could measure the signal from your afm with a multimeter. Turn the safc to zero and it should output the same figure.

      You’ll want to have the block drilled and tapped to suit 1/2in head studs and the head for the same. How much power do you intend to make?

      Sorry for resurrecting an oldish thread Not much has happened in the past year since the last update. The car did another 1000 miles or so and failed the MOT for the first time in October (failed on tyres which had been advised for a couple of years) In October the car got put up for sale and was removed in November due to no interest, being so close to christmas it was to be expected. The roads were dry in February so I decided to tax it early and get the new tyres fitted.   Fast forward to April, I got someone in to give the car a good clean after sitting for the winter.                                 The car got re-advertised and today (Saturday 3rd May) the car sold. The new owner is planning a GTR conversion at some point and a respray in the same pearl white. It's bitter sweet, it's a shame to have the car sit there for half the year and then only do 1000 miles. The kids are growing too quick and space in the back is getting limited. It's been a great 6.5 years of ownership

      And if you want more power, more reliably, and cheaper, go get the Aussie RB... The 4L Barra and put that in instead.

      No cats will keep discolouring the rear bar. Sends white paint a weird yellow stain. Cut and polish normally gets it out, but you'll be doing that every fortnight I found.

      Both heads will be equally reliable or unreliable depending on what you do to them.  Stock the RB26 head will flow more. You have access to the stock intake ITB manifold on the RB26 cheaply which flows really well(1000hp+).   Arguably more aftermarket support for RB26, though in Aus we love our RB30 SOHC heads too.    The only downsides to the RB26 head is if you have a VL commodore and want to keep the SOHC look.  Where you may have an issue is drilling out the rb30 block for the bigger head studs but if you are building a big power motor you'd probably put bigger studs on the SOHC head too.  This is just about finding a good machine shop, sometimes easier said than done.  RB30 head worked can make big power just like a Rb26 head, so really it actually more comes down to what your preference is for your car.  People now even making billet versions of both.
