Buying a Used A'PEXi Power FC From Japan: Prices and Fitment (2026)

The A’PEXi Power FC is not discontinued: A’PEXi still lists it, at ¥140,800 including tax for the unit, in a chassis list dated 19 January 2026. Used units are cheaper and plentiful, with an SR20DET Power FC selling for a median ¥49,800 (about $311) across 41 Yahoo! Auctions Japan sales that ended between 12 April and 7 October 2026. The main risk is buying the wrong part number, or a unit with no working Commander, because the listing title rarely tells you.

We checked A’PEXi’s official pages and read the closed auction results ourselves on 9 October 2026. Dollars are at ¥160 to $1.

Is the A’PEXi Power FC still made in 2026?

Yes, for a fixed list of cars. The Power FC is a plug-in replacement ECU: you unplug the factory computer and plug the Power FC into the same connector. A’PEXi’s product page still carries it, priced at ¥128,000 before tax. Since April 2022 the FC Commander, the small handheld screen used to read and change the maps, has been sold separately at ¥42,000 before tax (¥46,200 with tax).

The current list covers the S13, S14, S15 and 180SX SR20DET, the JZX100 1JZ-GTE, the ECR33 and ER34 RB25DET, the R32, R33 and R34 GT-R RB26DETT, the FD3S 13B-REW and a few others, such as the SW20 MR2 and Lancer Evolution V to VII. It does not include the early JZX90 and JZZ30 1JZ, the JZA80 2JZ-GTE, the RB20DET or the CA18DET. For those cars, the used market is the only market.

What A’PEXi’s page does not say is whether its dealers will sell a new unit for export. That is TBC. A’PEXi’s FAQ adds that setting is basically done on the car, at its dealers.

How much does a used Power FC sell for in Japan?

These are sold prices, not asking prices, from Yahoo! Auctions Japan (ヤフオク, yafuoku), Japan’s largest auction site. Junk-labelled units, harnesses, sensors and screen-only parts are left out.

Two patterns stand out. The early JZX90 and JZZ30 1JZ units cost three times a JZX100 unit, because A’PEXi no longer lists them. And only one 2JZ-GTE Power FC for the JZA80 sold in the whole window, for ¥165,000, so there is no median to give.

Listings described as new full kits (unit plus the current OLED Commander, part 415-A030) also sold: 12 for the JZX100 (414-T020) at a median ¥105,000, and 16 for the ER34 (414-N033) at ¥100,000. That is the seller’s description; we did not inspect them.

So what does a Power FC cost you, in practice?

Shipping and your own import tax come on top. A Power FC is small and goes by EMS or courier (EMS vs courier for drift parts); for the tax side, see import duty on JDM drift parts.

Which Power FC fits an S13, S14, S15 or 180SX?

The one with the right number on its label. A’PEXi does not make one Silvia unit. It makes 11, split by year and by airflow system: L-Jetro (the factory air-flow meter) or D-Jetro (speed-density, which reads a pressure sensor instead).

Old units on Yahoo often carry an older code instead, such as “SR2014” or “S15L 010-0175” in the title. Those are earlier generations that A’PEXi no longer prints in its list, so their fit is TBC until the label is matched to your car.

What are the FC Commander and the PC options?

The FC Commander is the handheld screen that plugs into the Power FC. It shows boost, ignition timing and injector duty, and lets you edit the fuel and ignition maps. Without one, the unit runs whatever map is inside it.

Not every Commander works with every unit. A’PEXi’s FAQ says that if the Commander stays on the A’PEXi logo screen, it is not compatible with that Power FC. Used Commanders sold alone for a median ¥16,375, and seven more sales were a third-party service replacing a Power FC’s aging capacitors (¥15,000 to ¥15,800). One seller felt the need to write 液漏れ無し (ekimore nashi, “no capacitor leakage”) in the title, which tells you what buyers worry about.

For PC tuning, A’PEXi’s own FC Commander PRO software can no longer be installed, because its authentication server has stopped (A’PEXi FAQ). Third-party PC interfaces fill the gap. Datalogit is the one most overseas tuners know, and PC communication adapters (some listed for FC-Edit and FC-Pro) sold 12 times on Yahoo at ¥30,000 to ¥35,000. None of these are A’PEXi products.

Can you buy a Power FC from Yahoo! Auctions Japan yourself?

Yes. A proxy bidding service will bid, pay and forward it, and 99 used units for the engines above sold in six months, so supply is not the problem. Reading the listing is. A title like “パワーFC S14” does not tell you whether it is 414-N030 or 414-N044, L- or D-Jetro, or if the unit was re-mapped for a bigger turbo and injectors by its last owner. Words like 実働外し (jitsudō hazushi, “removed from a running car”) or 本体のみ (hontai nomi, “unit only”) help, but most titles leave out the part number, the Commander and the map history.

A proxy buys what the listing says. It will not check that the label matches your car, ask whether the Commander comes with the unit, or ask the seller in Japanese whether the unit has been tuned, locked to another setup, or ever been wet. That is the step where overseas buyers end up with the wrong ECU.

Before you bid on any unit, run through this:
