does anybody know how to make the ecu enter base idle adjustment mode manually? i've heard unplugging the Throttlebody Position Sensor (TPS) and revving over 2000 3 times will enter it but how will i know i'm in when i try? anyone done it without a laptop putting the ecu in the mode?

thanks ;)

i know that the r33 uses the method you described, not sure about the 32. should also note that the engine has to be warm.

as to how you know when it's in base idle mode, well i don't think you can really know for sure, except that adjusting the idle screw should make a bt more of a difference than normal.

thanks. i got the cable now anyway and i can put it into base idle adjustment very easily now. thanks.

you seem like you know heaps about these cars so i'll try you, when my car gets really warm (not hot but full running temp) it feels like it gets a bit sluggish around 2000-3500 rpm. i hear it boost like normal but it just doesn't kick like when it's warming up. i mean like a quarter of the temperature guage as i never go past about a quarter throttle until the needle is a bit above cold.

do you have any ideas? it doesn't sound like i'm leaking boost.

info: stock internals as far as i am aware. (previous owner didn't say much)

r33 turbo and an unknown branded stainless steel dump.

dump back 3 inch exhaust (hollow cat i think)

codes i get from the ecu: knock sensor circuit, a/t signal (or something like that) it's a manual car though and i'm pretty sure it's factory manual.

    • Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked...

    • I think Fitmit had some, have a look on there (theyre Australian as well)
    • Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily. 
    • Actually, I'd say all three are the automatic option. Just the different trim levels. The manual would be RSFS, no?
