    what ever you go with, id chip it with the MINIMUM of a stock GSR map, but id really RECOMMEND you have a custom map made for your engine. Tuning is one of the biggest reasons people label the LSV as "unreliable".

    I would convert to OBD1 use a P28 with GSR maps... wait thast what i did do...

    there are only 2 VTEC obd0 ecus. PR3 and a PW0. I think only the PR3 can be chipped with turboedit... something about eproms or i dont know.

    good luck.

    convert to OBD1 its easy.
