Hi guys and girls,

I was just wondering if anyone has a Apexi Power FC in their cars and what the KNOCK LEVEL goes to.

For some reason i think my knock may be abit high!!

When it got tuned i told them just to do a SAFE tune, not looking for power just everyday drivability.

Its in a R34 GTR i know that if probably wouldnt matter what car it may be in.

But could you just let me know what car you have and what the knock level is

Thanks so much

Hey mate - Might get a better repsonce in the forced induction section!

What knock levels have you been recording mate and what sort of driving was it?

My car is just a 33gtst and normally on the road the highest I have had was around 60 because of bad fuel and a hot day. Normally see around 20 when I bring her out?

At the track though.....different story!

The knock sensor does and can pick up other noises which results in a high reading.

I did a supersprint at Bathurst and on my high boost tune/setting got 88 knock...but that was going 9/10th's (ripple strips, going quite hard so good chance it picked up other noises and stuff)

One point to remember is the frequency.

How often do you get the high knock reading?

Is it everytime you drive it?

Do you know what the tuner has set the knock warning at?

(Mine is at 60 and the engine light flashes)

Hope the helps mate,

Cheers!

Chris

Hey Chris

Thanks for your advice. Normally it sits about 20-30.

On a hot day it hit 45 that was the highest. But once it hit 64 cause it hit cut off!! and the engine light is set at 60

But tonight was about 30-38. I was told that 40-60 was pretty high.

So im just being cautious!!

Thanks once again

No drama's mate :P

With that reading - 30 - 38 was it evertime you drove the car - like drive car then 30-38. turn car off. turn back on and it would do that again?

If it reads constantly everytime you drive at that level, I'd be calling your tuner for a check up mate :)

Cheers!

Hey Chris no when it starts up it say 1 and the highest readings where between 30-38!!

I think im just being over pre-cautious!

Thanks for your advice!!

      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.
