ITS ALIVE!!!!!

[r34 gtr]

and i drove it in my driveway!!! its awesome. christmas came early this year, hehe. and the coolest thing was that it didnt even turn over once before it started; and this was using some tiny little denso battery we didnt even know worked! (came in the clip and i never threw it away! its awesome!) anyway, the car sounds awesome. it has this really lumpy idle (probably from the timing being drastically awry) but it revs just fine.

OF COURSE, there are some problems i need help solving (as always). heres what they are:

the safcII keeps trying to tell me that i have 25% airflow usage when the car isnt even running, and 40% (ish) when its idling. i hooked up the plug like i was told to. i dont understand whats going on..

and the second problem is that my freaking coolant overflow bottle is cracked and i cant find one intact in a junkyard. i dont want to pay $100 for one from the dealer (yeah, take care of yours. 100 bucks is insane for half a milk jug) so i was hoping one of you goys could direct me to a more reasonably priced option.

finally, i would like to say thanks to everyone who has helped me at any point with this leg of my car's journey to awesomeness. im sure ill be needing more help after christmas (if you catch my drift, hehe). i really appreciated everything, happy holidays to all!

Congrats ont your car running!!!! anyways for your coolant tank you can do any of these numbers http://search.ebay.com/coolant...omZR8

[biosehnsucht]

Mine's cracked too.

We slathered jb weld all over it, we'll see if it holds... at least my crack is above the MAX line..

[r34 gtr]

thanks, im really glad to be able to at least start it and hear it run. i cant wait to break it in.

my problem though is the maf. its being the biggest pain in the a$s. i wired it up like i was told to (as per sxoc, HT and the quick reference thing from pulsar gtr) but it reads crazy! the safc tells me its at about 25% when the car is off, and about 40% at idle. theres no way that is possible.

if it makes a difference, the plug i have isnt from a z32 to my knowlege. i have no idea what plug it is. the wires are nothing like the z32 plugs ive seen. it does fit though, and i have it wired up like the diagrams say (just put the wires to the pins they need to go to). im so stumped! heeeeelp! haha.

[r34 gtr]

edit: never mind about the maf. i got it sorted out.

new problem: as soon as the car starts, it dies. it wont idle. im not sure im actually doing anything when i mess with the safc, so that could have some part in it... but i still dont exactly have a good idea of whats wrong.

Do you have a stock/KA-E MAFS that you could hook up to at least get it running?

[JICdrifter]

i have a coolant catch in good condition. IM on aim: jplaya8

[iliketocrash]

i actually saw someone use a small gatorade bottle for an overflow bottle.

[jdmDAvey]

Ive got an overflow tank if you still want one. 15 bucks. mail me : [email protected]

[sultan]

jb weld should hold fine, i know a guy with a turbo B14 and his coolant overflow has jb weld all over the bottom where it's cracked. we even overheated it so bad the coolant was boiling in the overflow and the jb weld held no problem.

[r34 gtr]

i have the maf hooked up and it works fine. i get the correct reading with the safc and everything. the problem is that the safc isnt saving my adjusted fuel maps so the car is flooding out when it tries to idle. i really have no experience with the safc so my buddy is going to help me tomorrow. hopefully itll run alright then.

i did manage to drive it around the block several times today though, it was freaking awesome. the ride is so stiff, it jars your spine when you hit a reflector in the road! well, not that bad but you get the idea.

and for you guys with the extra catch tanks, youll be hearing from me... i guarantee it.

The SAFC is supposed to hold your settings even when power is taken away from it. Did you make sure you hooked the grounds up right? The two grounds are at least an inch apart on the ground wire on the ECU?

[r34 gtr]

ok, well, the settings and everything are in fact saved in the safc (though i did manage to screw it up a half-dozen times before i got it to save them) BUT the car still wont run. it starts and then immediately stalls out. it will run all day in the "get-u-home" mode when the maf is disconnected, but the safc is reading that the maf is correctly hooked up. i have no idea whats wrong. ive got it set to 2in 7out so there should be no problem there.. everything seems to be in order. even the aicv and aacv and all those things are working more or less. it also doesnt seem to matter if the car is warm or not. i warmed it up without the maf connected and it did the same thing when i reconnected it. it sounds like it HAS to be a problem with the maf, but i dont know of anything that could possibly be wrong, i mean, everything seems to be working fine.

there is of course the mystery of the swat ecu. have no idea what its doing. anyone want to burn me a chip for free? i would love you forever.

[r34 gtr]

help?please?

if it helps, the car is using: a z32 afm, evo 3 510cc injectors, gt28r turbo, fmic, safc and a chipped ecu. dont think any of the other parts count... it has been modified to run on 3 vacuum lines. the puzzling thing is that everything checks out like it should. none of the wiring has been tampered with since it was last running except for the z32 maf plug, which is wired correctly (though using a non-z32 plug, which does fit).

[float_6969]

Well tim, my first step would be to try and ghetto rig it back to how it was before and see if that fixes the problem. If it does, then you know thats where the problem is. Do you know what the ECU was chipped for? If not, the 2in/7out rule may not apply as it may have been chipped for a different mafs. I'd see if you can't get your hands on a stocke ecu and see where that gets you. If you pay for shipping both ways, I could loan you mine if you really need it. I won't need it for a few weeks yet.

[Looneybomber]

Well tim, my first step would be to try and ghetto rig it...

You know all about that one don't you? Hmm duct tape, flexy PVC pipe and running fuel lines from another car.

[float_6969]

Shush dude, you liked it! IIRC you helped too biatch!

[r34 gtr]

oh i love it... you should see the sheer amount of hardware store plumbing pieces on my car now. its like an exact replica of the "plumbing fixtures" section at home depot. oh, and inner tube from a bicycle, and electrical tape, and...oh its awesome.

anyone have the base ca18det map? if someone can send it to me i can have my friend burn me an eprom.

and the safc worked fine when i had it set to the ca18det maf. but maybe ill try it with the safc sending the z32 signal to the ecu.. worth a try..

[r34 gtr]

hey...the car wont fire now. im guessing its the ignitor. would that cause the stalling and junk? i dont think it would explain why the car would run on its "get-u-home" setting though. any ideas?

[r34 gtr]

awesome. thanks man.

[r34 gtr]

hey, ive got no spark now... i was wondering if anyone has got an ignitor they could sell me for cheap. i would go steal one off a q45 but those are quite hard to come by areound here.

- tim

[r34 gtr]

ok, nevermind. ive got spark like crazy, but when i try and turn the engine over, it doesnt fire. WHATS GOING ON?!?!?!!!! im so confused. i dont have a clue whats happening. i also dont know the first place to start looking for what could possibly be wrong.

by the way, the lack of spark was due to the battery being just low enough so that it would still turn the engine over, but didnt quite have enough juice to make a good spark. god i wish i knew what my car is doing.

- tim

[boost_boy]

Hope you didn't piss-off your ecu to the point where it's feelings are permanently hurt. The AFM circuitry in the ECU is so sensitive and can easily be damaged. The SAFC on 500+CC injectors is something I don't recommend, either.

[RMiller]

Maybe it's a fuel problem. Well it has to be if you have good spark. Injectors could be clogged. Does it run smooth or is it lumpy? Maybe your ecu is jacked. Have you tampered with it at all? Have you installed a chip? When your car dies, does the fuel pump shut off? Can you hear relays clicking on and off sporadically?

Put the E maf back on and get it running correctly with that. Your turbo won't require a different maf until you really up the boost.

[r34 gtr]

well, it flat out wont fire. i have plenty of spark but i guess it isnt enough when its under pressure. that or its firing at the wrong time. i do know that when i crank it, the voltage across my coils drops to 7.5-8.5 volts. even when its got more than one fully charged, deep-cycle marine batteries hooked up to it. im guessing ive got a relay thats gone bad or a fuse or my ignition switch is crapped out. im not quite sure.

and dee, i know the safc with 500+cc injectors is a bad idea, but unless i win the lottery i dont think i can afford anything else. but just for the record, how much is an e-manage again? maybe some friends and i could pull that off if i sell the safc. anywho...

got more than enough fuel.. no relays clicking on and off sporadically, ecu does have a chip, and it ran like butter when the maf was unplugged. this problem does not have anything to do with the z32 maf at the moment, though i may try the det maf on there if we get the ignition sorted out and it still doesnt run.

[biosehnsucht]

You say you have fuel and spark?

Do you know you have fuel from the injectors because ... ?

And the coils, yo usay you were getting spark but have you actually tested them w/ a multimeter for resistance? should be 0.6 - 0.8, I had one that was 400+ ohms and it fired some but not all the time..

also you have your ground strap on the coil subharness connected right? at the back of the engine..

[r34 gtr]

i know ive got fuel because i can 1) smell it, and 2) see it spray into the air when i take the plug(s) out and crank it over. the ground strap is connected, and i dont think the coils could have gone bad all at once, i mean, i didnt touch anything and i had driven it the previous day. and they always spark. it just doesnt fire when the plugs are in... its so wierd.

- tim

[RMiller]

Hmm...you either don't have fuel or spark. It's got to be one or the other. I see you said you have fuel misting out of the spark plug holes...maybe only 1 or 2 cylinders working. Check connections. Recently I had an injector plug come undone while driving.

Good luck...and MERRY CHRISTMAS.

hey, tim...if u can try to put the old 370cc back in there and see what it does.. cos as u said it..500cc+ on AFC = no no. I had the same problem when I install a 870 cc on my FC with out somekind of EMS. and if u can ..check the resistant on the MAF itself...u may have a bad MAF. just give me a call..I also have the overflow bottle laying around here that u can have.
