NEED info and suggestions on ECU/Harness set up...
 

I'm swapping in a LS/VTEC into my 94 civic EX/SI. I have a 5spd on the LS/VTEC but there is an auto in the car now. So I have 2 questions...
Can I run my stock AUTO P28 Ecu and AUTO harness for the new engine?
And, if so what should I do to to get the A/F mixture right? Some have said to chip the P28(if so where can I get a chip?) and others have said to just run VAFC Hack, or do both.
I am doing this swap in about a week and a half, and need to figure out this problem fast. Thanks alot guys. The only other thing is I dont know if the AUTO Ecu and harness will work with the new 5spd set up???
