Hi all, hope someone might be able to shed some light on this strange situation.

My engin light has been flickering on and of latley and only have noticed it when i am in 4th or 5th gear. Just cruising around and if i were to put my foot down to speed up it flickers.

Under hard acceleration through 1st to 5th gear it does not come on.

Has anbody had the same thing happen or can i get a few tip's on what to do?

Thanks in advanced.

the check engine light will come on to indicate knocking/pinging...its not good. The factory warning is set to come on at 60, which is pretty high...tuners like to keep it under 20 when tuning aftermarket ECU's

If its only happening in 4th or fifth gear, I'd say you're in the wrong gear to be accelerating that hard at the time, and putting too much load on the engine. if you were to drop back to 3rd and accelerate that hard, chances are you wouldn't get the knocking as it sounds like your car is fine the rest of the time....

Have you got an after market ECU and a tune? or still on the stock ECU?

Either way, its not good, so I wouldn't keep doing what you're doing...take it somewhere and get it checked out :stupid:

I'v only had the car about 6 weeks and know that it has a APEXi Power FC.

You said that the car might be knocking, I can't hear any noises like that. I used to be a mechanic about 4 years ago and i'v heard what that should sound like and i can't?

I never worked on car's like this before or up untill i bought it.

I do have planed to take it to a dyno and get it tunned fairly soon though.

you don't have the pfc hand controller do you? umm I seriously think there's a flaw in 34s pfc....I've heard ppls pfc sorta "detune itself" every few months, initially knocking at 5th then move down to 4th ..etc..

agree - definately knock

note ur load speed revs and gear to help the tuner out

i'd also consider in investing in the handcontroller (while they're still available)

feedback info on display very usefull (such as knock and water temp)

goodluck with it

Nah don't have one. Looks as though the previous owner didn't have one or sell it with the car. When you say hand controller is it conected to the PFC or not? Never seen one.

I suppose E-Bay or buy one brand new for the car?

I noticed this problem myself, except my engine light flashes very rapidly at the end of 1st and sometimes 2nd. Only saw it happen once or twice though, apparently the owner who I bought it off said his car would knock alot too. Is this a common R34 problem or could it be something on my end? As in the unit itself or the actual knock sensor?

Hi all!

Thanks to all that replied about the engin light.

I was able to get my car dyno tuned today by Castle Hill Exhaust and he brought back the timming a bit so the light would not come on. All is good now! Yeah!

My car started at 178kw and the final outcome of the tune was 199.9kw at the rear wheels. Very Pleased.

Thanks again :P

What sort of work has been done to the car to acheive those figures?

Hey mate...I wouldn't be running 15psi through the stock turbo...unless you want it to fail and have to replace it.....generally the safe limit for them is about 12psi...you might find you'll make more power on lower boost too....I make 200-205rwkw with the same mods on an R33 at 12psi...

It has a front mount intercooler, 3inch exhaust all the way through, Apexi power FC computer, K & N Air filter, HKS Blow off valve.

When dyno'd on saturday, it was running at 1 bar and now it has been adjusted to 15psi.

I don't understand how i will make around the same power running less boost :thumbsup: can you tell me how that is?

I still am learning a lot about the car, only had it 6weeks.

      WGNC34 - floor mats

      Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car

      All my Polish car culture insight comes from watching Nightride. So I half expect this to get 1UZ swapped eventually?! Are you going to drive it in winter? I'm always curious how ATTESA would hold up in the snow. There isn't that much opportunity to try it in Australia.
