Before i take it to a tuner...just got a power fc second hand from another r33 skyline...ive noticed it was mapped for a vg30 airlow meter when i started her up...it didnt want to idle....i changed it to the coresponding AFM and she started beautifully...i also noticed the car was completly cold and it didnt give me that warm up rev? (that higher than usual rev like normal ecus do... is this normal for a PFC?) and another thing once it acutally warmed up... i took it round the block for a drive and everthing seemed fine....switched her off and tried to start it and she wouldnt start again? :confused:

Any PFC gurus out there that could possibly figure this one out? as its all new to me and any info would be greatly appreciated :headspin: :headspin: :)

Worth a try, first job is to list his mods side by side with yours. If there are too many differences it is usually better to staret from scratch (ie; the default Apexi maps).

In the second menu from the top you'll have to change the settings to 4 door mode aswell to compensate for the extra weight :D

Thanks for the tip....:)

whilst playing with the hand controller next to the function for extra doors............ i saw a function saying VL goodness please select :shake: :shake:

Do you know the exact mods that the other car had, Steve?

Put yours on one side and their's on the other and let us have a look at it. If they're vastly different, i reckon it's probably best to reset it back to factory....oh and don't forget to turn the Apexi Boost Control setting off.

Oh and cut off those unneseccary doors, dude.

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated.

I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.

      Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.

      Freddy Plenum vs Genuine options RB25

      My return flow is custom and puts the return behind the reo, instead of at the bottom. All my core is in the air flow, rather than losing some of it up behind the reo. I realise that the core really acts more as a spiky heatsink than as a constant rate heat exchanger, and that therefore size is important.... but mine fits everything I needed and wanted without having to cut anything, and that's worth something too. And there won't be a hot patch of core up behind the reo after every hit, releasing heat back into the intake air.

      There is a really fun solution to this problem, buy a Haltech (or ECU of your choice) and put the MAF in the bin.  I'm assuming your going to want more power in future, so you'll need to get the ECU at some stage. I'd put the new MAF money towards the new ECU.
