The TL J32A V6 is a capable engine in a well-sorted chassis, and standalone ECU management through the Haltech Nexus gives you access to what it can actually do.
The 2005 Acura TL J32A has real potential, and the factory ECU is the main thing standing between where it is and where it can go. The Tuned By Shawn Boomslang PNP Wiring Harness for the Haltech Nexus connects directly to your factory harness without any permanent modifications, giving the Haltech Nexus full standalone engine control. No cutting, no splicing, fully reversible.
