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.

      Version 1 aluminium airbox is.......not acceptable No pics as I "didn't like the look.....alot" Even after all my "CAD", and measurements, the leg near the fusebox just didn't sit right as it ended up about 10mm long and made the angle of the dangle look wrong, the height was a little short as well, meh, I wasn't that confident that Version 1 was going to be an instant winner I might give Version 2 another go, there's plenty of aluminium at work, but, after having in on and off a few times, and laying in the old OEM airbox without the new pod filter and MAF, there may be an option to modify the OEM air box and still use the Autoexe front cover and filter.... maybe This >  Needs to fit in here, but using the panel, and not the pod, the MAF will need to fit in the airbox though> I'm thinking as the old OEM box and Autoexe cover that is sitting in the shed is just sitting around doing nothing, and they are relatively abundant and cheap to replace if I mess it up and need another, it may well fit with some modifications to how the Autoexe brackets mounts to the rad support, and some dremiling to move it get in there, should give me some more room for activities, as I don't want to move the MAF and affect the tune Sealing the hole it requires to stick it in the air box is simple, a tight fit and some pinch weld will seal it up tight  I am calling this a later problem though

      and it ends up being already priced in as though you're just on 91RON without any ethanol. Car will lose a bit of economy as the short and long term fuel trims bring down the AFR back to stoich or whatever it is for cruise/idle for the engine.

      Oh, you are right. But, in Australia E10 is based on 91RON fuel and ends up being 94RON. Hence it being the cheaper option for economy cars. The more performance oriented cars go for the 98RON fuel that has no ethanol mixed in. The only step up we have left then at some petrol stations is E85.

      There is a warning that "this thread is super old" but they ignore that anyway...

      With 10% Ethanol, we're talking 2-3% fuel consumption difference. The emissions reductions and octane boost in my opinion far outweigh this almost non existent loss.    My tanks sitting at 80%. Luckily that should go down fast as I'm on vacation again for the next two weeks.
