The Accord V6 J35A is a smooth, capable engine that responds well to proper calibration and rarely gets standalone ECU attention.
The Honda Accord V6 J35A has more in it than the factory ECU allows, and proper standalone calibration is how you find it. The 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.
