R33 IDLE HUNTING UP AND DOWN

Hi guys

 

Just have a issue with my R33 gtst series 1

While im driving and turn the steering wheel or making a half turn the idle will go up and down between 800rpm and 1500 rpm and as soon as i come to a stop and wait 5 seconds or so it will return to normal idle and will go away for a while until i turn again

Happens 90% of the time when i do a half turn and the car is warmed up or when im driving the car to warm it up also

I dont have a afm and ecu is adaptronic ecu

 

Anyone experienced these type of issue and has any idea to why it could be doing that

With the adaptronic, there is an adjustment for additional idle effort for steering. You will most likely need to adjust this value up or down until it becomes stable. A slight increase in revs when the wheel is turned is desirable. If you don't already have the software, get onto the adaptronic website and download it.

If the adaptronic is controlling the idle, then the idle tab in WARI is the first place to look (or that eugene program, but I dont like it yet).

Are you settings close to default values?

Another issue could be the fuel and/or ignition map inherently creating oscillations in RPM due to lean-rich-lean cycles in that area of the map.

Can you post an ECU file?

      I've heard the Tomei USA head gaskets are decent if you want to o-ring the heads but otherwise not recommended.

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.

      Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.

      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
