Toyota GR86 remap
Bought for the drive, not the spec sheet. Whether yours lives on the daily commute or comes out for track days, the GR86 asks for a calibration that respects what a naturally aspirated flat-four can honestly give up. Call 0161 302 5117 to talk through your car.
Every service available on the GR86
Stage 1 calibration on the FA24 is the headline service, and it is a refinement job rather than a boost-driven power hike, more on that below. A standalone rolling road session is worth booking on its own, with or without a remap attached, and gives you a documented baseline figure for track prep or simply to know what your car is producing. Launch control coding is available where the car is specified with it from the factory. We do not offer Stage 2 on the naturally aspirated FA24. There is no supporting hardware pathway on this engine that would justify one, and we would rather say that plainly than sell you a package that does not exist.
Why GR86 owners remap
Two kinds of GR86 owner come through Eccles. The first drives the car daily and wants sharper throttle response and a cleaner delivery through the rev range, the sort of change that makes the car feel more alive without altering how it behaves. The second owns the GR86 for track days and wants the same refinement plus a documented dyno figure to work from when setting up the rest of the car, tyres, alignment, brakes.
Neither owner is chasing a big bhp number, because the FA24 does not have one to give without forced induction. What both get from a properly developed calibration is a car that responds more precisely to input, which matters more on a lightweight, balanced rear-wheel-drive platform like this one than raw peak power ever would.
Engine and stage options
The GR86 runs Subaru's FA24 2.4-litre naturally aspirated flat-four, jointly developed with Subaru and shared with the BRZ, producing 231 bhp from the factory. There is no turbocharger to build boost against, so a Stage 1 calibration works on timing and fuelling refinement rather than raising a boost target. for the exact improvement achievable on this platform, but expect a genuine, modest sharpening rather than a large power jump. Stage 2 does not apply here. See our Subaru BRZ page for the same engine covered from the other badge.
A visit to Eccles
A GR86 booked in for Stage 1 starts with a baseline pull on the 4WD Bapro dyno, establishing exactly what your engine is producing before anything changes. Samuel Gunnell reads the ECU via Kess3 or CMD bench tooling, in person, and develops the calibration from that baseline data rather than a generic file. Verification pulls on the same rollers confirm the result before you leave. If you are here for a standalone rolling road session, the process is the same minus the mapping stage, and you walk away with a documented figure either way.

Book your GR86 in at Eccles. Contact us on 0161 302 5117 or through the website to arrange a date. We are at HNA Facilities, Plot Zero, James Nasmyth Way, Eccles, Manchester M30 0SF, and every calibration is developed on your car's own data with an honest account of what the FA24 can deliver.
