Compare Pedal Commander fits for the Acura TL and RL by generation and engine, and learn which throttle controller matches your chassis before you order.
Quick answer
Choose the Pedal Commander listed for your exact Acura chassis: TL owners need the PC22 for 2003–2008 third-gen cars or the PC20 for 2009–2014 fourth-gen cars, while RL owners with the 2005–2012 KB1-KB2 3.7L Base use the PC20. The main trade-off is that one part code can cover multiple TL generations, but the RL listing is narrower and only fits the 3.7L Base.
Why the TL needs a generation check before ordering
The Acura TL spans two distinct generations in the Pedal Commander catalog, and they do not share the same part code. Third-gen TL models from 2003–2008 with the 3.2L or 3.5L V6 use PC22. Fourth-gen TL models from 2009–2014 with the 3.5L or 3.7L V6 use PC20. That split matters because the throttle response controller is matched to the car's electronic architecture, not just the engine size. If you order by engine alone, you can end up with the wrong unit for your model year.
Why the RL listing is narrower than it looks
The Acura RL listing covers the KB1-KB2 generation from 2005–2012 with the 3.7L engine and the Base trim. Unlike the TL listing, which names multiple trims including Advance, Base, Technology, and Type S, the RL listing is specific to the Base trim. If your RL is a different trim or engine, the catalog does not confirm fit, so you should verify before ordering rather than assume the RL label covers every variant.
The real trade-off: broader TL coverage vs a simpler RL match
The TL option gives you two part codes across two generations, which means more research but broader coverage for the popular TL chassis. The RL option is simpler because there is one code for the covered KB1-KB2 3.7L Base, but it leaves less room for variation. Neither approach is better in isolation; the right choice depends on whether your car falls inside the listed envelope. Both listings use the same selection prompt—'Which Acura TL Do You Have?' or 'Which Acura RL Do You Have?'—so the ordering step is the same, but the answer you select must match your chassis.
Trade-offs to weigh before you order
- TL third-gen (2003–2008): Use PC22 for 3.2L or 3.5L V6 models. This is the older chassis, so confirm your model year falls in the 2003–2008 window before selecting this code. If your TL is a 2008 model with the 3.5L, PC22 is the listed match.
- TL fourth-gen (2009–2014): Use PC20 for 3.5L or 3.7L V6 models. This code is shared with the RL listing, but the TL application is distinct and should be selected through the TL option. Do not assume PC20 fits every 3.7L Acura; the chassis selection still matters.
- RL KB1-KB2 (2005–2012) 3.7L Base: Use PC20 as listed for the Base trim. The RL listing does not name other trims, so if your RL is not a Base, verify fit before ordering. RL owners with a non-Base trim should treat the listing as unconfirmed rather than universal.
Product facts
- Pedal Commander for Acura RL: Pedal Commander for Acura RL is listed for the KB1-KB2 (2005–2012) with the 3.7L engine and Base trim, part code PC20. RL owners outside that generation, engine, or trim should confirm fit before ordering, because the listing does not cover other configurations.
Pedal Commander for Acura RL - Pedal Commander for Acura TL: Pedal Commander for Acura TL uses PC22 for the 3rd Gen (2003–2008) 3.2L–3.5L V6 and PC20 for the 4th Gen (2009–2014) 3.5L–3.7L V6, with trims including Advance, Base, Technology, and Type S. TL owners must pick by generation and engine, not by trim name alone, to get the correct part code.
