Honda Shift Knobs and Fk8 Type R Table Additions

Our initial release of Accessport tuning for the Honda platform has been overwhelmingly positive.  Both end users and Protuners have provided overwhelmingly positive feedback of the Accessport, included Off The Shelf Maps, and Accesstuner Pro functionality for the FK8 Type R which we released in December of 2023.  We haven’t just been sitting back, though.  Our Honda development and COBB Hard Parts teams have been hard at work.

Today we are happy to release our tried-and-true COBB Knobs for the FK8 and FL5 Civic Type R. Aside from the Accessport, the COBB Knob is one of the longest standing pieces of our catalog and it only made sense to whip some up for the Type-R.  These bad boys are machined from billet stainless steel and medical grade delrin which combine for a nice weight and comfortable grip.  A perfect complement to the Honda shifter.

Our software team has also been hard at work adding nearly 100 new tables to our Accesstuner Pro software suite, used by authorized COBB Protuners to create custom calibrations for supported vehicles.  Accesstuner Pro and Accessport firmware also now features 16 new monitors/gauges.

COBB Knobs for Honda

Introducing our COBB Knobs for both the FK8 and FL5 Honda Civic Type R.  We are offering two flavors, both standard and tall, for the FK8 and a standard option for the FL5.  All are constructed of a machined stainless steel core that sits inside of a perfectly matched piece of machined delrin.  The stainless steel cores create a noticeable increase in heft compared to the factory knob.  Both standard versions come in at 264 grams, the tall at 332 grams – a nice increase from the factory knob’s 179 grams. Aesthetics are important in a knob too, everyone has different preferences.  That’s why we offer the Honda COBB Knobs with either black or white delrin.  Each comes with both a black and red anodized aluminum trim ring that you can easily swap to match your car’s interior.

FK8 Type R Accesstuner Pro Table Additions

The quality of a tune is often a product of both a calibrator’s tuning experience, depth of knowledge, and power of the tools they are using.  Our Honda development team has hopped right on requests from our Honda Protuners to define and test functionality of additional factory tables.  We’re excited to release nearly 100 new tables to help Protuners better control Boost Control, Fueling, and Torque management.
