well look at that, the answer was already in your question

 

well i heard i might need some other jumper harnesses for sensors and im wondering if i should buy a already chipped ecu or a stock one

 

I have a 2000 si and I didn't need any other harness. You'll need a p28 ecu to chip for hondata...stock is OBD2 and not able to alter.

 

thanks for the clarification i just wanted to make sure i only needed one harness and the p28 and i was wondering if im goin to notice a big differance once i do this

 

oh yea sorry one more question what is my stock ecu obd2a or obd2b so i can get the right jumper harness

 

1996-1998 = obd2a
1999-2000 = obd2b

If you're stock...no. If you've got cams and a number of other mods, yes.

you dont necceserily need a p28 ecu, any OBD1 Vtec ecu will work, i have a 99 si with a p61 (OBD1 GSR ecu..only came in the 92-93 GSR'S) chipped with hondata s200 with a skunk 2 jumper harness other wise refered as a conversion harness..i wasnt tryin to be a dick or *** hole bout it i was jus sayin...

 

thanks for filling in the holes I left. Good stuff

 

no problem buddy
