Honda Civic remap: what the GAN box does and doesn’t do
More power and torque without rewriting the ECU or replacing any parts. Unlike a flash remap, the tuning box leaves the ECU software alone and only adjusts the engine sensor signals.

Honda Civic chip tuning: engines and generations
Honda Civic remap: the answer changed in March 2017
Can a Honda Civic take a tuning box? Yes, but the right box depends on the model year and the engine. Until 2017 an ordinary petrol Civic had no turbo; turbocharging was left to the Type R FK2 of 2015. That changed in March 2017, when the Mk10 arrived with the 1.0 VTEC Turbo at 126 hp and the 1.5 VTEC Turbo at 182 hp.
The 1.5 VTEC Turbo takes the GAN GT, and in 2018 and 2019 the Mk10 also offered a 1.6 i-DTEC diesel with 120 hp. In Britain the Mk10 Civic was sold from 2017 to 2022, when the Mk11 replaced it. Before 2017 the larger gains belonged to the diesels, at 30 to 43 hp in the catalogue, against 10 to 17 hp for the 1.4 and 1.8 petrol engines.
Which GAN box suits which Civic
Diesel Civics are matched to the GAN GT. In UK badging, i-VTEC means petrol, i-CTDi and i-DTEC mean diesel, and VTEC Turbo and Type R are the turbocharged petrols. The Mk7 1.7 CTDi is an Isuzu-built engine with 101 hp, produced from January 2002 to September 2005. The 2.2 i-CTDi in the Mk8, built from January 2006 to August 2010, makes 140 hp and 340 Nm.
On the Mk9 the 2.2 i-DTEC with 150 hp ran from October 2011 to December 2013, and the 1.6 i-DTEC with 120 hp joined it from January 2013. The petrol i-VTEC engines, from the 1.4 at 100 hp to the 1.8 of the Mk8 and Mk9, go with the GAN GA+. The Mk8 Type R, a 2.0-litre petrol with 201 hp, has its own entry and also uses the GAN GA+. The Mk8 Hybrid is quoted at 95 hp from the petrol engine plus 20 hp from the electric motor.
Honda Civic remapping: questions
Civic 1.5 VTEC Turbo remap: what does the GAN GT add?
On the GAN GT the 1.5 VTEC Turbo goes from 182 hp and 240 Nm to 234 hp and 312 Nm. These are the stated gains for the engine type, not a dyno reading taken from your own car.
How much do the diesel Civics gain?
The catalogue lists 41 hp and 93 Nm for the 2.2 i-CTDi 140, 43 hp and 95 Nm for the 2.2 i-DTEC 150, and 36 hp and 85 Nm for the 1.6 i-DTEC 120. Go by the engine name and the build date, because the two 2.2 diesels have different outputs. UK used buyers often weigh the 1.6 i-DTEC diesel against the 1.8 i-VTEC petrol, and the GAN GT is the box for the diesel.
What does a tuning box do on the 1.8 i-VTEC, and what does it not touch?
On the Mk9 1.8 i-VTEC with 142 hp the GAN GA+ adds 17 hp and 21 Nm, and the GAN GA+ gives up to 12% more power. Some Mk9 1.8 i-VTEC engines can use more oil than normal. A box does not cure a worn part, so have the oil consumption checked before you fit it.
Civic tuning box or flash remap?
A flash remap replaces the factory software inside the engine control unit (ECU). The GAN box works from outside: it sits between the engine sensors and the ECU, so the factory software, checksums and flash counter stay untouched. Your manufacturer's warranty is preserved: the ECU software is never changed, and the box can be removed at any time.
Does a GAN tuning box affect my car insurance?
Tell them. A tuning box raises the output, and in Britain that is a declarable modification like any other performance change. Policies differ, so a quick call to your insurer before fitting is the safe route; the figures they will ask for are the stock and GAN outputs listed here.
Is a tuning module the same as a Stage 1 remap?
Not quite. Stage 1 usually means an ECU remap without replacing any parts. The tuning module also works without replacing parts, but it does not change the ECU software: it adjusts the sensor signals, comes off in about a minute, and the OFF button in the app restores the factory settings.
