HA Motorsports custom ECU adapter harness for installing our Neptune Auto ECU with separate transmission control unit into '00-'01 Integra with B series engine and automatic transmission.
The stock 2000-2001 OBD2B Integra controls both the auto transmission and engine from within the ECU. This works great for the stock engine, but once you've done engine modifications and need a tunable ECU it becomes a problem as the stock ECU is not chippable/tunable. By directing transmission operation to a separate transmission control unit, you are able to use our Neptune Auto ECU to control/tune your engine without loosing automatic transmission function.
* For use on '00-'01 Integra with automatic transmission only.
* Must use our Neptune Auto ECU, will not work with any other ECU configuration.
* Uses all OEM connectors and pins for OE fitment and durability.
All HA Motorsports ECU's, products, and services include a One Full-Year VIP Warranty
