I currently have a P12 ecu in my 1992 honda prelude S. The car just got rebuilded and I am planing on running boost to it in about a month. I am looking to run around 15 to 20 psi.
Q) do I need to buy a new ECU in order to run S300. and if so what ECU do you recommend using.
I know I can use any OBD1 ecu that is non vtech, but I am wondering if there is a superior one.
Different ECU
To use a Hondata system, you will need to use a compatible OBD1 ecu from the list at http://www.hondata.com/ecus.html .
