Размеры, параметры и распиновка МАФов (Airflow Meter)

Airflow Meter	Found on Vehicle	Label	Wire colour vs Function	Size	Notes
CA18 AFM	Nissan Silvia S13		Pin A - nothing / not needed Pin B - +12v power Pin C - ground Pin D - air flow signal out	65mm
SR20 AFM	Nissan S14/200SX		Pin A - nothing / not needed Pin B - +12v power Pin C - ground Pin D - air flow signal out	65mm
RB20 AFM	Nissan Skyline R32		Wire A - Not Connected Wire B - Signal Wire C - 12v Ground Wire D - Signal Ground Wire E - 12v Power	80mm	Same size and calabration as Rb25 AFM
RB25 AFM Series 1	Nissan Skyline R33 Series 1		Wire A - Not Connected Wire B - Signal Wire C - 12v Ground Wire D - Signal Ground Wire E - 12v Power	80mm	Can be used on RB26 in twin form as an upgrade from the standard AFM's (ECU Change required)
RB25 AFM Series 2	Nissan Skyline R33 Series 2		White with Blue Trace - Ground Orange with Black Trace- Signal Black with White Trace - 12v Power	80mm	Same size and calabration as Rb25 AFM
RB26 AFM	Nissan Skyline GTR Twin Turbo		?????????	65mm	Label is same colour as Z32. This is the smallest unit which is 65mm opening diameter. Is it very obvious which AFM is a Z32 and which is an RB26 from the phyiscal size, despite same colour label. The part no is A36-000 J70
RB26 NISMO AFM	Nissan Skyline GTR Twin Turbo		?????????	65mm	This AFM has the resolution of the Z32 but has the same size as the stock, so you can keep the same piping, air intake and tubing as stock. The part no is A36-000 J71.
Z32 AFM	Nissan 300zx Twin Turbo		Wire 1 - Not Connected Wire 2 - Signal Wire 3 - 12v Ground Wire 4 - Signal Ground Wire 5 - 12v Power Wire 6 Not Connected	80mm	Same size as RB20/RB25 but has higher calibration. Should be good for around 350rwkw. Perfect swap into Rb20/Rb25 as bolt pattern is identical and no change is required. RB30 AFM plug fits which can be had very cheaply from any nissan/holden wrecker
Q45 AFM	Nissan Infiniti Q45 V8		Wire 1 (White) - Signal Wire 2 (Black) - Ground Wire 3 (White & Black --have seen red and black--) - 12v Power	90mm	Higher calibration and larger diameter airflow meter. Has been known to go upto 450rwkw. The physical body of the unit is larger and it wont fit standard pod filte adapters or airboxes. It is just over 3.5" in diameter on the outside. The inside diameter is 3".
