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?

    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
    • So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
