Hondata

im planning on putting a turbo on my 92 si hb with jdm b18c5. gonna use s200 with p28 ecu. was wondering if i just need the stock p28 ecu because when i tried looking for a ecu all i seen were chipped ecu's. i'm thinking i only need a stock one because the s200 is going to take care of all the settings. is this true?

Yes, the S200 will take care of everything. You only need a stock ECU. If you can only find a chipped ECU, you can remove the chip and install Hondata, but you will probably pay a lot for a chipped ECU.
