** DISCONTINUED ** This ECU package has been discontinued and replaced with the KTuner End-User / PRB ECU package.

This is the most economical ECU setup for K series engine swaps into 88-00 civic / 90-01 integra chassis. Low on price, but high on features and power potential. The HA Motorsports Budget K-Swap ECU features a reprogrammed K series ECU with a custom basemap tune based on your engine setup. The ECU casing is refinished using our traditional glass-bead blasting process and topped off with a clear ECU lid for extra show. Fuel, ignition, cam angle, and VTEC tables are pre-programmed to take advantage of common upgrades that are done when doing a K20 or K24 engine swap like intake, header, and exhaust so that you get the most power from your swap.

Please select your programming choices from the drop-down menus, then write in any additional setup information in the comments box during checkout. We will program your new ECU before shipping for simple plug-n-play operation.

This ECU is designed for use with 05-06 style engine harnesses. If you are using an 02-04 style engine harness, you will also need our K series ECU Jumper Harness so that the ECU will plug into your engine harness.

What about the immobilizer?
Stock K series ECU's all have a built in immobilizer that will prevent the engine from starting if not used on a vehicle with a correctly programmed key. 88-00 Civics and 90-01 Integras do not have a compatable immobilizer system for use with this ECU. To solve this issue, our K-Swap ECU has the immobilizer system disabled within the ECU so that a programmed key is no longer needed. The multiplex unit and emissions related controls are also disabled for your convenience.

I'm using an 02-04 RSX transmission. Can I still use this ECU?
Absolutely! We can program the ECU to work with the 02-04 style speed sensor without any further modifications needed. You will not need to install a different speed sensor or do any extra wiring! Simply select your transmission from the drop-down menus above.

Can I have this ECU tuned for my car on a dyno?
Yes. This ECU is setup for use with the KTuner system. The ECU is socketed so that a KTuner dealer board or end-user board can easily be plugged into the ECU and reprogrammed. The ECU can be further tuned/reprogrammed at any KTuner dealer that offers dyno tuning (subject to dealer tuning and reprogramming fees).

Can I upgrade this ECU later?
Yes. If you wish to further upgrade this ECU, all you will need is a KTuner End User System. The KTuner End User System will plug directly into this ECU with no further modifications needed.

Do I need a laptop to use this ECU?
No, the ECU is ready for use as-is. The ECU is pre-programmed to run you engine without any further modifications or programming. Simply plug-in and start your engine.
