A factory airflow meter contains a hot-wire sensor. It measures passing air through temperature changes caused by airflow. Strictly speaking, the sensor creates resistance, and intake piping cannot be wider than the meter, which is why many very high-powered cars omit it.
Bee Racing often uses HKS F-CON V Pro, priced at ¥120,000 in this article, which can control either a factory airflow meter or pressure sensor and allows fine adjustment. [Historical technical explanation]
…the cables and terminals. To avoid trouble, though, we minimize extensions. The key is combining wiring where possible and removing unnecessary wires. Essential wiring such as headlights is routed low in the engine bay where it can't be seen. It's laborious, and wiring is prone to problems, so asking a professional is the safer choice.

Thanks as always to the shops and expert drifters! Readers and staff alike appreciate your precise advice. This column teaches us so much each month that we feel we should pay tuition rather than receive a salary. Don't worry—we have no intention of charging consultation fees, so please send questions freely!
Who makes the sunroof and Airone gate? Question from ‘FC in hospital,’ Ibaraki
In June's Hot Twin pages, the Redbo crew's FC and 180SX appeared…
…right? I'd like to ask about that FC's transparent sunroof. The factory option is body-colored, isn't it? Please explain.
Also, is the Airone gate sold commercially?
The sunroof was replaced with acrylic! Answer: Koga of the Redbo crew
The sunroof is acrylic. The sort sold at home centers…
…I thought that material was too thin and weak, so I bought 6 mm acrylic from a specialist and cut it to the factory sunroof's size. Then I drilled holes and mounted it like the original panel. It still slides and tilts.
I bought the Airone gate from an aero shop some time ago. I wonder whether it's still sold.
…my partner Yamashita's shop is planning to make a cool new one, so look forward to it!
The sunroof acrylic reportedly cost about ¥7,000. Yamashita's shop, Yamato Power , plans to make an original Airone gate.

I want better response! Question from ‘Mobile Suit Laurel,’ Iwaki. Hello! I enjoy reading the magazine. Recently response has been poor, so…
…can Trust's RB25 surge tank or the RB26 six-throttle setup Nao uses this year fit an RB20?
Could clutch slip or a burned flywheel also cause it? Please explain.
See page 166! Answer: Drift Tengoku editorial staff. RB20 and RB25 intake port spacing is completely different…
…thank you.
…so the Trust surge tank won't fit. RB26 throttles don't fit directly for the same reason. [Continuation:] The Cefiro has an RB26 throttle conversion! See page 166 for details. [Further continuation:] …it can feel that way because revs rise without the car moving much.
However, this month's Cefiro diary is for such owners! The car built by TS Factory… [Separate continuation:] About the clutch: slipping can actually give the illusion of improved response…

How does a setup without an airflow meter work? Question from Nonaka, Tomi, Nagano
Cars without airflow meters often appear in Drift Tengoku. In such…
…without an airflow meter, how is the fuel mixture set? Please explain the advantages and disadvantages of running without one.
It costs money, but has many benefits! Answer: Imai of Bee Racing
In most setups without an airflow meter, a pressure sensor replaces it…
…and measure the pressure of air passing through the piping to determine air quantity. Compared with the factory hot-wire type, this can measure intake air reliably and reduces intake resistance, improving response… [Historical explanation in the magazine]
The disadvantage is cost. Reprogramming the factory computer alone cannot…
…those are benefits.
…so a computer such as V Pro or Power FC is used for control. Dedicated intake piping is also needed.
Without an airflow meter, the pipe between the turbo and air filter is straight, which looks efficient. Some drag cars even leave the turbo inlet exposed.
I want a cleaner engine bay! Question from ‘Long live Silvia,’ Nakatado-gun, Kagawa
I drive an S14. Recently I've seen cars with the battery and fuse box…
…moved into the cabin in magazines. It makes the engine bay look clean and cool, and I'd like to do it, but don't know how. Could the magazine explain required materials, relocation methods and precautions in detail?
You'll need motivation and persistence!
Answer: Yoshida of Super Made. We drill a hole in the bulkhead and relocate them. The materials needed are wiring for extending…
The fuse box is in the passenger footwell and the battery in the trunk. Avoid pulling on bundles of wires. Sometimes some pulling is unavoidable, but it can break wires or connections, so handle everything as carefully as possible. [Historical caption]
