What it is and what it fits
SR20 cars with the 64-pin blue ECU header: S13 Silvia/180SX SR20DET (not CA18DET), S14a (facelift) Silvia SR20DET, S15 Silvia SR20DET and SR20DE, RNN14 Pulsar GTI-R, N15 Pulsar SR16VE, N14 Pulsar with distributor.

What it does
- Direct swap for the factory SR20 ECU in S13/S14a/S15 drift cars, no rewiring.
- Adds launch control, anti-lag, flex fuel and closed-loop boost control to an SR20.
- Powered CAN port can supply 12V to a CAN dash or keypad.
- Spare ignition drives can be repurposed as auxiliary outputs.
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 Link 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. $2,275 is the price authorised Link dealers advertise, and DEFI is an authorised Link 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?
Link ECU 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 Link standalones on our hub dyno in Corona, and we can review logs remotely if the car is somewhere else.
