My car: 96 Prelude w/H23a1 OBDII
Decided to go with Hondata S200 since Vaportrail is one of the best tuners and he is only 1 1/2 away.. I was on Hondata website trying to find which ECU I should go with. They don't list anything for a 96 h23a..They only list 92-95 h23a..Does this mean that I can't use Hondata? I'm confused..

 

You need to buy the OBD-2 to OBD-1 conversion harness from somewhere, and run the s200 on the OBD1 ECU recommended by hondata. You don't need to change anything else though, other than just buying the harness. I'm currently running a 4b on a P28 in my '96 Prelude VTEC.......

Thanks...I feel like an idiot knowing it was that simple. Makes sense know...The conversion will allow me to look at the ecu's that work for the obdI h23a...
DUH..thanks again

 

You need an adapter harness, and a P72 GS-R ecu. Hondata will disable the VTEC on the GS-R ECU. It's the best choice as it allows you to keep your secondary intake butterflies (IAB). Which especially with the torque of the H23 you'll want to keep.

But as http://www.hondata.com/vehicles.html shows you have lots of options for ecus...just have to decide whether you want the IABs or not

 

Ahhh it looks like the s200 solved the IAB option for the h23a's finally. Thank god they did this AFTER i had the 4b!
