Just ordered a B18C online for my 99 intergra LS but the engine came with USDM ECU. Will a JDM b18c run right with USDM ecu???

any answers would be great! thanks...

If its the right OBD and isn't the ITR engine yes, but you will have a check engine light because USDM engines have a knock sensor and jdm do not. It wont affect the performance.

This is assuming you have a USDM P72. Always use premium gas too on Vtec engines due to the slighty higher JDM compression or it wont run properly.

Thanks alot man!

Everything is OBD2, had to get a wiring harness for a LHD and got a vtec sub harness from RYwire to make sure everything is plugged in... just wanted to make sure that was pretty much it for a JDM engine with the USDM ecu
