Suzuki Alto Works HA11S/HB11S F6A Turbo MT Tuning ECU, Limiter & Boost Cut Removed 33920-73GA0
HA11S/HB11S アルトワークス F6A ターボ MT車用 チューニングECU 書き換えコンピューター リミッター&ブーストカット解除 33920-73GA0

This is a reflashed/tuned ECU (engine computer) for a Suzuki Alto Works HA11S/HB11S with the F6A 3-cylinder SOHC turbo engine paired to a 5-speed manual transmission. It is genuine Suzuki/DENSO hardware, part number 33920-73GA0. The seller removed it from their own car after a spec change and stored it indoors for about a year before listing. According to the seller, this ECU was previously purchased on Yahoo Auctions as an already-reflashed tuning unit, and the prior owner stated it has the speed limiter cut and boost cut removed, with a handwritten note (partially faded) mentioning boost behavior above 130 km/h. The seller confirms it worked normally in their car right up until removal, but has not been able to verify operation since then because they no longer own a vehicle to test it in. Buyers must verify their own connector shape and part number compatibility before bidding, as fitment cannot be guaranteed.
Seller grades this as having minor scratches and dirt (やや傷や汚れあり), noting cosmetic wear such as scuffs, grime, rust spots, and a peeling label, plus a leftover green tape note from the prior owner on top of the unit. Functionality has not been retested since it was removed from the vehicle about a year ago.
Shipping: Seller plans to ship via Yamato Takkyubin. No other shipping terms, surcharges, or combined-shipping details are mentioned.
