Your options for OBD2 are Emanage, FMU/Missing link, or VAFC hack, all which suck. If you want the motor to last, you need to think about a chipped OBD1 ECU running Uberdata, Crome, or Hondata. They all do the same thing and should be tuned by someone who knows what they are doing. Tuning is not something anyone can pick up and do.
