actually 20 deg is the 5th mark from the left. the marks from the left are, 0 5 10 15 20 25 30. ignore any reading you get in consult at idle and go off the timing light.

which throttle body and TPS are you running? are you sure your unplugging the correct TPS plug?

the 4th mark from the left. on conzult my timing sits on 15 degrees when at idle.

how do i get to base idle mode using my consult cable?

4th mark is 15 degrees. as qwk32 said (and i meant to say), the 5th mark is 20 degrees, 4th mark is only 15 degrees, so your timing is correct as it is at the 4th mark which is 15 degrees and the consult is showing 15 degrees.

sorry, i meant the 5th mark. i cant go any lower than the fifth mark with the tps unplugged.

also when idling normally with the tps in, i can set it to 15 degrees easily and the car runs nicely

when i pull the tps plug out it runs like crap and i cant set it any lower than 20

i cant be pulling out the wrong plug? probably am;

heres a pic of the one im pulling out. this is an rb25neo out of a stagea

just double check that colour of the wires of the plug match the colour of the wires of the plug on the tps, since both it and the plug underneath send wires off in the same direction.

the two plugs at the top both go to the tps.

sorry i should have mentioned, the bottom one (grey one) also goes to the TPS but it is a Throttle On/Off switch and is associated with an auto. what ecu are you running do you know? and auto or a manual one?

the black plug is the variable TPS signal you unplug when setting timing.

ok so one if those plugs is for the tps and the other is for the throttle valve switch because this engine was from a auto stagea

do i pull out both plugs?

as above mate, you posted as i was replying. you don't unplug the bottom plug to set the timing. if your running the auto ecu, which isn't a problem, just make sure the bottom plug is plugged in incase the ecu is looking for that signal to help with idle time controls.

ive been running an auto rb25neo stagea ecu; when warmed up and at idle timing sits at 15 degrees on the conzult software

when i put the car into base idle mode and try to adjust the timing i cant adjust it any lower than 20 degrees and it idles really rough.

i just tried a r34 manual rb25neo ecu; when warmed up and at idle timing sits at 5 degrees???? on the conzult software

and when i put the car in base idle mode it idles fine and am able to adjust the timing across the whole range

what options do i have?

problem solved.

used another timing light to confirm my readings. now its set to 15 degrees

and the car drives and runs fine

only problem is it wont start unless i remove the cas and turn it manually.

when its warm it starts without a problem

      My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.

      Automatic Power Button Light Flashing

      Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).

      Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers

      Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.
