Paired with a Nexus Rebel LS terminated harness, it provides a comprehensive range of performance and tuning capabilities for GM LS engines

REBEL LS FAQS
When can I buy it?
The Nexus Rebel LS is available for pre-order now! Haltech is aiming to have the Rebel LS in our hands by March!
This looks a lot like an R3, is it the same thing?
No. For practical reasons, the case is the same as an R3, but that’s about it. The Rebel LS is intended to be a cost-effective, quick, and easy solution for running LS-engined vehicles, and thus the specs and functionality are quite different from the R3.
Can I integrate the Rebel LS with other Haltech products?
Yes, the Rebel LS is fully compatible with the iC-7 dash, PD16 PDM (Up to four of them), EGTs, Multiple external wideband sensors, CAN Keypads, etc.
Will it support my automatic transmission?
Not yet. We plan to expand the range to include some popular automatic transmissions in 2024.
I don’t have an LS. Will there be a Rebel for my engine?
Maybe, however, there are no current plans for other variants.
