About the generation

What makes the Honda Accord VIII special

Honda Accord VIII tuning: the sporty version is a diesel

The largest catalogue gain in Honda Accord VIII tuning is 51 hp, and it belongs to a diesel, not a petrol engine. The Type S of the CU saloon and the CW Tourer has the 2.2 i-DTEC N22B2 with 180 hp and 380 Nm, against 150 hp and 350 Nm for the base engine. The catalogue lists the Type S engine at 179 hp, and with the GAN GT it gains 51 hp and 101 Nm.

The base diesel also works with the GAN GT and gains 43 hp and 95 Nm. Both diesels stayed in the range after the facelift of 2011, and European production of the Accord ended in 2015. Honda Accord 2008 tuning covers the first cars, built from May 2008.

The petrol Accord VIII

The petrol engines are the 2.0 i-VTEC with 155 hp and 190 Nm and the 2.4 i-VTEC, which gives 201 hp and 230 Nm with the manual gearbox. Both are naturally aspirated and use the GAN GA+. For Honda Accord chip tuning on a petrol car the gain is therefore much smaller than on the Type S diesel. The Tourer estate has had the same engines from the start.

Questions

Honda Accord VIII chip tuning: questions

Accord 2.2 i-DTEC Type S tuning: how much more power does the 180 hp engine get?

In the catalogue the Type S has 179 hp and 380 Nm, and with the GAN GT it reaches 230 hp and 481 Nm. These are the stated gains for this engine type, not a dyno reading of your car.

What does a tuning box add to the Accord VIII 2.0 and 2.4 i-VTEC?

The 2.0 i-VTEC gains 19 hp and 23 Nm, and the 2.4 i-VTEC with 201 hp gains 24 hp and 28 Nm. The GAN GA+ gives up to 12% more power, and both gains sit at that level.

What should you check on a 2.2 i-DTEC before fitting a tuning box?

Two parts deserve a look on this diesel: the diesel particulate filter (DPF), which clogs on short trips, and the flexible EGR bypass hose, which can crack. The box adds power and does neither of those jobs.

Is a tuning module the same as a Stage 1 tune?

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.
