What it is and what it fits
Wire-in (universal). 12 injector channels (6 cylinders with staged/secondary injectors, or 12 cylinders) and 12 sequential ignition channels: V12, V10, or staged-injection 6-cylinder builds such as 2JZ, RB26, VR38 (wire-in).
What it does
- Same case, connectors and I/O as the KV8 with four more injector and ignition channels
- Staged injection on a six-cylinder lets a high-power build run a second injector bank sequentially
- Fully sequential ignition for up to 12 cylinders
- Dual wideband lambda and dual knock built in
- Shares the KV harness and plug kits, so a KV8 install can be upgraded without rewiring the connector side
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 Emtron 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. $3,600 is the price authorised Emtron dealers advertise, and DEFI is an authorised Emtron 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?
Emtron publishes no CARB Executive Order for this unit. It is competition engine management: not legal on a pollution-controlled vehicle in California, and a vehicle running it will not pass a smog inspection. We are not going to imply otherwise.
Can you tune it for me?
Yes. We calibrate Emtron standalones on our hub dyno in Corona, and we can review logs remotely if the car is somewhere else.
