KAE-T refuses to run...battery died

[sstomek]

i hooked up my n60 maxima maf and filter to the turbo (i am also running a Apexi SAFC) and attempted to start the car. Cranked it, it idled up to 2000rpm and went down and died (this all happening in a span of about 1-2 seconds). I try to crank the car again and the battery is dead. Could there be a problem with the wiring from the MAF to the SAFC? I am charging the battery as I am typing this so I only tried cranking the car once after i hooked up the MAF. Am i being paranoid or could there be something causing the battery to die? For more background info read next paragraph.

After finishing mounting all the turbo parts (safc, socketed ECU with custom tune, turbo, IC, BOV, waste gate, injectors) I decided to try and start the car with no MAF. The car would start and die almost immediately and there would be a lot of white smoke. Mike (s13fx) told me that the car was running rich probably due to the fact that there was no maf so the safc was dumping a bunch of fuel. So after that, I attached the n60 maf and then the problem i described above occurred.

MAF or no maf the car should start. If you got bigger injectors then you'd be sprayign tons of fuel without a maf and no safc or ecu to correct it. so car may not run/idle but should start at least once or twice... Check spark plugs...Is your ECU tuned for the n60 mafs? What's your settign on the safc for hotwire in an dout. If your ecu is tuned for it then safc in and out should be the same numbers like 2 and 2 or 5 and 5 I run 1 and 1Battery dead is result of lights on lol, bad alternator, or alternator fuse...

spark plugs should be fine. I am not sure if the ecu was tuned for the n60 since mike(s13fx) made the tune. Maybe he will chime in tomorrow and be able to give a little more information. Although I do know the tune was made for 550cc injectors, T3/T4 60 compressor side .48 hotside, and 93 Octane gas all of which are on my car now. Since the battery is still charging I cant check the safc settings but from what i remember i think it was like a 4 and 4. not 100% sure though. In terms of the battery I will let it charge till tomorrow morning and try to turn on the car again, making sure the hotwire in and out settings are the same and I shall post results.

Thanks for the help,

Tom,

Once again homey your SAFC settings are probably all screwed up, and you never called me last night just texted me I hate text messages LOL.

Anyways call me up at work today Il help you get the proper SAFC settings. The SAFC should be set to 0 all across the board since the ECU is chipped and tuned for 550cc injectors.

Another thing is are you 100% sure the new injectors you got are 550cc too?

In anycase homey give me a call today and we can fix this. It seems like it's a simple problem.

PS: Every SAFC I have ever turned on straight after not being hooked up was always put on MAP by default that would explain why your car won't even run. I also remember telling you to un hook the SAFC from the maf and hooking up the stock maf cause then you would have no doubt in your mind that it's the SAFC causing the problems.

yea i definitely have to play with the SAFC settings. The battery kept dying because even though my trunk was closed the trunk light was still on. After i changed the settings to hot-wire and it was 3 in 3 out i turned the car and it idled beautifully at about 1000 rpm. then about 30 seconds later it bogged down and died which was pretty weird. I think i still need to play around with the SAFC settings a bit more, or it might be those injector clips. I am going to the junk yard in about 20 minutes to get the injector clips and a fuse.

Just go to your ecu...unhook the safc mafs wires and hook them back to factory... to see if car runs..... if you used the proper connectors no tools needed...
