Hi all just a simple one when im reving my car out at about 5500rpm this orange light lights up on my dash saying "check" it only really flashes on and off but still comes up. What is it? I've included a pic so you know which one its the yellow one in the top right.

Your engine is knocking, it comes on with a knock reading over 60. Get your car looked at immediately or you could do serious engine damage. Could be caused by poor tuning, bad fuel, bad plugs ect ect.

exhaust, z32 afm, apexi pod, power fc, fmic. But i had to reset the the power fc so its running untuned at the moment. Do you reckon once it's tuned it should be ok?

yes. have you selected the Z32 AFM in the menu (if you have reset the STD AFM will be selected)...it may cure the problem...until properly tuned.

the engine is seeing more air than the Z32 is indicating (its probably set up for the STD AFM)...hence the injectors are not putting enough fuel in your engine. The power fc should run rich with a base map with the Z32 selected so should be nice and safe.

it might not apply here, but turning OFF the optional boost controller on the pfc off sounds similar to what you're describing.

on the hand controller, go to:

Etc mode

Function Select

Boost Control Kit

then opposite to whatever its on now (it will be in japanese).

if it doesnt work then change it back.

That leaves the light on all the time and in some cases the car won't start (probably dependant on firmware version).

no... my mates r33 had the same problem after he reset his pfc. only came on under load past 5k.

Funny how it would detect that the boost controller was not there all the time but only display the fault after 5k rpm under load on a base tune.

I'm only going off what my PFC does and what's in Paul's PFC FAQ.

In my experience the car wont even start with the boost controller setting set ON if it's not plugged in.

As for the bloke's original problem, I think running around with the base PFC map is a pretty bad idea. It's designed so you can putt it to the tuner not so you can drive the car every day. The fact that you don't even know what a check engine light in is even scarier... Take the PFC out and put your stock ECU back in before you cost yourself thousands of dollars when you have to rebuild your motor.

Either that or stop driving it until you can tune it... its not rocket science...

im 100% sure it does what he is describing with the BC setting on. my mates did it after a reset as i mentioned. i went through the settings to turn it off and it doesnt do it anymore.

it is just a thought anyhow, if it doesnt work for him then move on.

guys, its the knock reading on the power fc going above 60. the first reply was correct.

if you go to monitor, and select knock as one of the channels, then press right so it displays the maximum you have reached on the right side of the screen. rev it out and watch the little light flash, then look at the max value you have reached.

i guarantee its more than 60. this is why you need to tune the car, to stop the engine pinging and get it running healthily. go now and do it lol.

I recently got my Power FC installed in my R33 GTST. I had the same problem to start with but the light stayed on all the time not flashing. This was because my boost control warning sensor was turned on when i didn't had the boost controller kit.

when i was on the high rpm like 6000, the engine check light started flashing as the knock reading was like 89-97. So i had to take my car for dyno tuning again. If you are getting the high knock reading, Check your map on the power fc and locate the point on the 20*20 cells when the light flashes. You have to reduce few degrees on the timing from that cell and the neighboring cells as well.

I am still getting same problem but its not due to knocking, its AFM as my stock AFM is maxed out.

Tuning should fix your problem.

I took car in today to have it dyno and the guys told me, your car is running TOO LEAN.

What does that mean/ Can effect will it have on my engine, car because I will not get to the tuner shop til Friday?

I have these mods, TM boost control, POD of some kind, split dump pipe, full exhaust with 3" tip, Axexi Power FC and a FMIC.

Any and all helpful answer are cool.

The one dyno run at 13.5 PSI was 194 rwkw.

That light wont come on till 78 knock on standard skyline so its actually quite high from factory not 60, anything under 60 once you get it tuned is desirable and what tuners look for, it wont detonate on the first ping but if u continue to drive with it contiually pinging it will go bang....

      I had 3 counts over the last couple of weeks once where i got stranded at a jdm paint yard booking in some work. 2nd time was moving the car into the drive way for the inspection and the 3rd was during the inspection for the co2 leak test. Fix: 1st, car off for a hour and half disconnected battery 10mins 4th try car started 2nd, 5th try started 3rd, countless time starting disconnected battery dude was under the hood listening to the starting sequence fuel pump ect.

      This. As for your options - I suggest remote mounting the Nissan sensor further away on a length of steel tube. That tube to have a loop in it to handle vibration, etc etc. You will need to either put a tee and a bleed fitting near the sensor, or crack the fitting at the sensor to bleed it full of oil when you first set it up, otherwise you won't get the line filled. But this is a small problem. Just needs enough access to get it done.

      J50 clock date suddenly reset to January 1

      By suko · Posted

      The time is always correct. Only the date is wrong. It currently thinks it is January 19. Tomorrow it will say it is January 20. The date and time are ( should be ! ) retrieved from the GPS navigation system.

      Buy yourself a set of easy outs. See if they will get a good bite in and unthread it.   Very very lucky the whole sender didn't let go while on the track and cost you a motor!

      Well GTSBoy, prepare yourself further. I did a track day with 1/2 a day prep on Friday, inpromptu. The good news is that I got home, and didn't drive the car into a wall. Everything seemed mostly okay. The car was even a little faster than it was last time. I also got to get some good datalog data too. I also noticed a tiny bit of knock which was (luckily?) recorded. All I know is the knock sensors got recalibrated.... and are notorious for false knock. So I don't know if they are too sensitive, not sensitive enough... or some other third option. But I reduced timing anyway. It wasn't every pull through the session either. Think along the lines of -1 degree of timing for say, three instances while at the top of 4th in a 20 minute all-hot-lap session. Unfortunately at the end of session 2... I noticed a little oil. I borrowed some jack stands and a jack and took a look under there, but as is often the case, messing around with it kinda half cleaned it up, it was not conclusive where it was coming from. I decided to give it another go and see how it was. The amount of oil was maybe one/two small drops. I did another 20 minute session and car went well, and I was just starting to get into it and not be terrified of driving on track. I pulled over and checked in the pits and saw this: This is where I called it, packed up and went home as I live ~20 min from the track with a VERY VERY CLOSE EYE on Oil Pressure on the way home. The volume wasn't much but you never know. I checked it today when I had my own space/tools/time to find out what was going on, wanted to clean it up, run the car and see if any of the fittings from around the oil filter were causing it. I have like.. 5 fittings there, so I suspected one was (hopefully?) the culprit. It became immediately apparent as soon as I looked around more closely. 795d266d-a034-4b8c-89c9-d83860f5d00a.mp4       This is the R34 GTT oil sender connected via an adapter to an oil cooler block I have installed which runs AN lines to my cooler (and back). There's also an oil temp sensor on top.  Just after that video, I attempted to unthread the sensor to see if it's loose/worn and it disintegrated in my hand. So yes. I am glad I noticed that oil because it would appear that complete and utter catastrophic engine failure was about 1 second of engine runtime away. I did try to drill the fitting out, and only succeeded in drilling the middle hole much larger and now there's a... smooth hole in there with what looks like a damn sleeve still incredibly tight in there. Not really sure how to proceed from here. My options: 1) Find someone who can remove the stuck fitting, and use a steel adapter so it won't fatigue? (Female BSPT for the R34 sender to 1/8NPT male - HARD to find). IF it isn't possible to remove - Buy a new block ($320) and have someone tap a new 1/8NPT in the top of it ($????) and hope the steel adapter works better. 2) Buy a new block and give up on the OEM pressure sender for the dash entirely, and use the supplied 1/8 NPT for the oil temp sender. Having the oil pressure read 0 in the dash with the warning lamp will give me a lot of anxiety driving around. I do have the actual GM sensor/sender working, but it needs OBD2 as a gauge. If I'm datalogging I don't actually have a readout of what the gauge is currently displaying. 3) Other? Find a new location for the OEM sender? Though I don't know of anywhere that will work. I also don't know if a steel adapter is actually functionally smart here. It's clearly leveraged itself through vibration of the motor and snapped in half. This doesn't seem like a setup a smart person would replicate given the weight of the OEM sender. Still pretty happy being lucky for once and seeing this at the absolute last moment before bye bye motor in a big way, even if an adapter is apparently 6 weeks+ delivery and I have no way to free the current stuck/potentially destroyed threads in the current oil block.
