No.will you do $50 shipped for just the harness?
Doubt it since OBD 1 is pre 96. I'll bet the ECU pinouts are drastically different as well.Will this work with a 91 Prelude SI2.0 B20A5 5SPD Manual?
what does this really do? and would it be useless on an auto?
^^^^ This is somewhat true. if your lude is obd2 the computer will wanna reset back to the factory settings. it is more of an adjustment than a tune. not a bad way to get a little more power out of your lude for pretty cheap. it's fun adjusting when your VTEC kicks in at about 4200rpm... more power earlier in the power band!!It allows you to tune/adjust A/R ratios and change your VTEC engagement point.
And yep its a pretty effective way to get some extra power out of the lude with a tiptronic tranny.
