Beastmode panda Posted August 31, 2012 Share Posted August 31, 2012 Hi guys.Basically, when i went to the tuners to have my fueling done and boost turned up we could only make it to 0.8 cause 2 of the wires had been cut on the fcd by a previous owner (for unknown reaons). So i bought a new one and we fitted it last night, turned the car on and the EML light was on, i went to rev the car a bit and it just spluttered and cut out. So we cut the yellow and white wire in half, just like how the old fcd was cut. And it ran fine like before.. Now obviously this is why the wires got cut in the first place but i can't turn the boost up without all of the wires there can i? (so the tuner guy said). So what do i do? Why is it making the eml light on when the yellow n white wires are connected?HELP. Quote Link to post Share on other sites
TrisK Posted August 31, 2012 Share Posted August 31, 2012 How many wires does your FCD have?Should be 4 wires. a 5 wire one makes the car run like ass Quote Link to post Share on other sites
akyakapotter Posted August 31, 2012 Share Posted August 31, 2012 Get it mapped on emanage blue problem solved Quote Link to post Share on other sites
Beastmode panda Posted August 31, 2012 Author Share Posted August 31, 2012 Yeah 4 wires man, no 5th wire was involved!? we only used the red black yellow n white, and the yellow and white make the car run like shit?? why? :s Quote Link to post Share on other sites
russ78 Posted August 31, 2012 Share Posted August 31, 2012 try and get a pic up of how its wired sure someone will shed light on your problem Quote Link to post Share on other sites
zebedee Posted August 31, 2012 Share Posted August 31, 2012 (edited) What make of FCD did you get? Edited August 31, 2012 by zebedee Quote Link to post Share on other sites
_shaun_ Posted August 31, 2012 Share Posted August 31, 2012 The red And black are just for power aren't they? So with out the other 2 wires the fcd is doing nothing . Sounds like guy who fitted last one cut the wires just to hide the problem Quote Link to post Share on other sites
Beastmode panda Posted September 1, 2012 Author Share Posted September 1, 2012 It's HKS bro's.Yeah i know that haha, but when we hooked the NEW one but to how it was supposed to be done, following the wiring diagram the car ran like shit WITH the yellow and white connected but fine with them cut! ((((I just wana know WHY it runs so bad with all of the wires connected :s. Quote Link to post Share on other sites
russ78 Posted September 1, 2012 Share Posted September 1, 2012 it might be your 12volt source is not strong enough try wiring it to another 12v that you know is good and the earth somewhere else Quote Link to post Share on other sites
zebedee Posted September 1, 2012 Share Posted September 1, 2012 Few ideas:Have you got the correct HKS FCD for a starlet?Does it hit fuel cut with the boost turned up without the FCD fitted?Just wondering if you have a mapped ecu in there thats not marked up and the fcd is upsetting it. I've had a mapped ecu before with no external signs that it was mapped only when i opened it up could i see the daughter board. Quote Link to post Share on other sites
Beastmode panda Posted September 1, 2012 Author Share Posted September 1, 2012 On the ad it said it was 100% suitable for ep82 and ep91.It doesn't hit fuel cut, works fine.I have an oem ecu dude, as far as i know anyway :s.Im not too familiar with electrics TBH, my friend does all my stuff (works in a car electronics store), knows what he's doing. Anyway, when i went to get the fuel set up the guy said we cant run it at a bar as planned cause of the wires being cut, so he said buy a new fcd n ill do it for nothing when you have the new one installed. so i got the new one and fitted all the wires but no luck, well it ran, but cut out when you revved it and the eml was on.Just really want to know how to make it run ok with all the wires . I'll ring the guy today and tell him. Quote Link to post Share on other sites
zebedee Posted September 1, 2012 Share Posted September 1, 2012 What boost is it running at the minute mate? Quote Link to post Share on other sites
Beastmode panda Posted September 1, 2012 Author Share Posted September 1, 2012 0.8bar matey, wanted to run a bar when i got the fueling done but the guy said i couldn't due to the cut wires and to buy the new one and he'd do it for free.. except the new ones just like the old one so i've wasted my money atm haha.

russ78 Posted September 1, 2012 Share Posted September 1, 2012 i would print the pic below off and go check, double check, then triple check the wiring layout your mechanic has done as 9 out 10 times its the wiring is incorrecthope this helps Quote Link to post Share on other sites
russ78 Posted September 1, 2012 Share Posted September 1, 2012 (edited) by the way the wiring diagram is looking ecu side, easiest thing to do is count down to each wire on the drawing then do the same on the ecu to check that each wire corresponds to the diagram.im not saying your mechanic dont know his stuff but its easy to make a mistake and its clearly not the FCD at fault Edited September 1, 2012 by russ78 Quote Link to post Share on other sites
ryan lang Posted September 1, 2012 Share Posted September 1, 2012 mine did exactly this wednesday when fitting it dude, earth the black wire to the body, and make sure the red wire is connected up tidy, only needs a 5v feed set it to 12, try it, if it hits fuel cut, turn the car off and turn it to 11, then turn it down 1 notch at a time until you stop hitting fuel cut.

ryan lang Posted September 2, 2012 Share Posted September 2, 2012 haha let me know how it went dude, hoping it went okayalso, russ78, the wiring diagram is looking at the ecu as though the plugs are in it, and you looking from the wire sidethey need to be looked at like the loom/plug is in your hand like so: Quote Link to post Share on other sites
russ78 Posted September 2, 2012 Share Posted September 2, 2012 the diagram is of the ecu side meaning its the female end or the ecu showing what the male plug plugs into its a guide to show you corrisponding pins so obvously you would wire it from the back as this would be how it plugs into the ecubut i can see how you think it meant something else Quote Link to post Share on other sites
ryan lang Posted September 2, 2012 Share Posted September 2, 2012 haha yeah just read it back mate i find pictures help lots so i had to do it haha Quote Link to post Share on other sites
