What it is and what it fits
Universal flagship: engines up to 12 cylinders or 6 rotors; pro drag, drift and circuit cars needing ECU + PDM + dual wideband + logger. Harness separate (HT-185200/185201 universal, HT-186200/186205/186206 terminated).
What it does
- Haltech's top-tier unit: 18 injector drivers allow primary + secondary injection on a V8.
- Sixteen powered outputs (4 x 25A, 12 x 8A) replace a separate PDM for most race cars.
- Two on-board wideband controllers for per-bank closed-loop fuelling.
- 512MB of on-board logging and three CAN buses for dashes and expanders.
- No internal MAP sensor - an external sensor is required.
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. $4,415 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.
