What it is and what it fits
GM LSx V8 with drive-by-wire and EV6 primary injectors; plugs into the engine's OEM ignition sub-harness (required, not included). Breakouts for 8 secondary injectors, transmission and PDM loads.
What it does
- Flagship R5 sold with a harness already terminated for LSx sensors, DBW and EV6 injectors.
- Harness carries breakouts for secondary injectors, cabin/engine-bay spare I/O and PDM loads such as lights and wipers.
- Fuel pump and fan are driven straight from the R5's 25A outputs, with pre-crimped leads supplied.
- Dual wideband and flex-fuel sensor connections are built into the harness.
Fitted and tuned on our hub dyno, or shipped to you
Buy it and fit it yourself, or have us do it. We install, wire and calibrate Haltech engine management in our Corona shop and tune it on a Mainline ProHub hub dyno, with the full sheet at the end. Shop labor is $265 an hour, quoted against your car; the calibration is priced on the standalone tuning page.
It is in stock in Corona and ships free anywhere in the continental US. Alaska and Hawaii are quoted by phone. If you would rather collect it, or have it waiting here for your install, say so at checkout.

Questions
Before you buy
Is this the price other dealers charge?
Yes. $5,965 is the price authorised Haltech dealers advertise, and DEFI is an authorised Haltech dealer. Shipping in the continental US is free on top of that.
Will it fit my engine?
Read the fitment above against your engine, sensors, injectors and throttle before you buy. If anything is unclear — a part number, a connector, a transmission — call us first. That conversation is free; a wrong unit is not.
Can I return it if it is the wrong one?
No. There are no returns or exchanges on third-party hardware once it ships — the manufacturer’s warranty is the warranty. That is why we would rather answer the fitment question on the phone before you order.
Is it street legal?
Haltech sells this for sanctioned off-road and competition use on vehicles that are not emissions-controlled, never on a public road. There is no CARB Executive Order: it is not legal on a pollution-controlled vehicle in California, and a vehicle running it will not pass a smog inspection.
Can you tune it for me?
Yes. We calibrate Haltech standalones on our hub dyno in Corona, and we can review logs remotely if the car is somewhere else.
