{"product_id":"mmx-performance-f8x-s55-power-control-module","title":"MMX Performance F8X S55 Power Control Module | M2C, M3, M4","description":"\u003cp\u003eThe MMX Performance F8X S55 Power Control Module is a clean-sheet alternative to traditional ECU tuning for the S55-powered M2 Competition, M3, and M4. After more than 12 months of in-house development, the PCM is far more than a piggyback box, it functions closer to a secondary ECU, with a standalone PCB running MMX's own calibration and communicating in parallel with the factory ECU to optimise charge air pressure, ignition, and fuelling in real time.\u003c\/p\u003e\n\u003cp\u003eThe result is a substantial increase in power and torque across the entire powerband, but delivered the way MMX prefers: smoothly, safely, and reliably, without compromising drivability or efficiency. The PCM keeps the OEM ECU intact and untouched, which is what enables the headline benefit: it's completely removable, leaves no trace, and is undetectable when removed. For owners who want serious gains without committing to a flashed ECU, this is the cleanest path on the platform.\u003c\/p\u003e\n\u003cp\u003eEach module is housed in a finned billet aluminium case, anodised in MMX gloss black, and mounted on a carbon fibre bracket. The wiring loom is vehicle-specific, every SKU corresponds to a particular S55 variant, with calibration tuned for that car's stock output. Installation is plug-and-play into the engine bay sensor harness; no ECU removal, no permanent modifications, no special tools required.\u003c\/p\u003e\n\u003cp\u003ePainstakingly engineered and hand-assembled in the UK to OEM-level quality.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Details\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eStandalone PCB with MMX in-house calibration\u003c\/li\u003e\n\u003cli\u003eFully removable and undetectable once removed\u003c\/li\u003e\n\u003cli\u003eBillet aluminium case, finned for cooling, MMX gloss black anodised\u003c\/li\u003e\n\u003cli\u003eCarbon fibre mounting bracket included\u003c\/li\u003e\n\u003cli\u003eVehicle-specific wiring loom: select your variant from the dropdown\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's Included\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePCM unit (billet aluminium finned case)\u003c\/li\u003e\n\u003cli\u003eVehicle-specific wiring loom\u003c\/li\u003e\n\u003cli\u003eCarbon fibre mounting bracket and hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eVariant Output\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMMR50-1603: F87 M2 Competition: stock 405 HP \/ 550 Nm → 494 HP \/ 625 Nm (+89 HP \/ +75 Nm)\u003c\/li\u003e\n\u003cli\u003eMMR50-1604: F87 M2 Competition Sport: stock 444 HP \/ 550 Nm → 494 HP \/ 625 Nm (+50 HP \/ +75 Nm)\u003c\/li\u003e\n\u003cli\u003eMMR50-1605: F80 M3 \/ F82\/F83 M4 Competition: stock 450 HP \/ 550 Nm → 520 HP \/ 660 Nm (+70 HP \/ +110 Nm)\u003c\/li\u003e\n\u003cli\u003eMMR50-1606: F80 M3 \/ F82\/F83 M4 (base): stock 431 HP \/ 550 Nm → 510 HP \/ 650 Nm (+79 HP \/ +100 Nm)\u003c\/li\u003e\n\u003cli\u003eMMR50-1607: F80 M3 \/ F82\/F83 M4 Competition Sport: stock 460 HP \/ 600 Nm → 520 HP \/ 670 Nm (+60 HP \/ +70 Nm)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eVehicle Applications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/ind-distribution.com\/collections\/m2-competition-f87\"\u003eBMW M2 Competition (F87)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/ind-distribution.com\/collections\/m2-cs-f87\"\u003eBMW M2 CS (F87)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/ind-distribution.com\/collections\/m3-f80\"\u003eBMW M3 (F80)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/ind-distribution.com\/collections\/m4-f82-f83\"\u003eBMW M4 (F82 \/ F83)\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eNotes\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eF87 M2 (N55 engine) is NOT compatible with this S55 module.\u003c\/li\u003e\n\u003cli\u003eIncludes a 1-year manufacturer warranty against defects in materials and workmanship\u003c\/li\u003e\n\u003cli\u003eDesigned and tested in the United Kingdom\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/ind-distribution.com\/pages\/faq#faq-emissions-notice\" target=\"_blank\"\u003eView emissions compliance notice\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eNot for sale or use in California\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IND Distribution","offers":[{"title":"F87 M2 Competition","offer_id":47411641581762,"sku":"MMR50-1603","price":1013.51,"currency_code":"USD","in_stock":true},{"title":"F87 M2 CS","offer_id":47411641614530,"sku":"MMR50-1604","price":1013.51,"currency_code":"USD","in_stock":true},{"title":"F8X M3 \/ M4","offer_id":47411641647298,"sku":"MMR50-1606","price":1013.51,"currency_code":"USD","in_stock":true},{"title":"F8X M3 \/ M4 Competition","offer_id":47411641680066,"sku":"MMR50-1605","price":1013.51,"currency_code":"USD","in_stock":true},{"title":"F80 M3 CS \/ F82 M4 CS","offer_id":47411641712834,"sku":"MMR50-1607","price":1013.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/0784\/7874\/files\/54149160030_29ee8b2524_b.jpg?v=1776276777","url":"https:\/\/grocerygetterperformance.com\/products\/mmx-performance-f8x-s55-power-control-module","provider":"Grocery Getter Performance","version":"1.0","type":"link"}
