That may be tru, but wanting any tunability in our cars, you will need to buy an OBD1 ecu and conversion harness, otherwise you will be stuck at stock redline, with many of the OBD2 restrictions on top of that.

As far as the S100 vs, the S200, unless you plan to run boost at a later time, then is really no point in getting the S200, and, yes, it may be upgradeable, but unless you are extremely serious about road racing, the only options to upgrade are datalogging and that G-chip, and as interesting as they both are, both are very un-necesary.

In any case, the Hondata is more expensive, but what you pay extra, you get in tunability and drivability...
