I have a 98 HX and I would like to put in a 99 SI ECU. Is this possible with my wire harness, will it work, and if so how much would i benefit from it.
You cant use a 99-00 ECU with a 96-98 wiring harness. Plus your car would most likely run like crap since the Si is a DOHC VTEC engine and your car has a SOHC VTEC-E engine.
