Can you put hondata S200 on this ECU. Its for a OBD2 GSR. The guy is asking 20.00 plus my old ECU. My plan is to put it with a H23A Vtec motor I have coming.

 

nope, hondata only works with obd1 unfortunately. the OBD1 P72 is a good (probably the best) ecu to run with hondata on the h22 or h23 vtec because it has the capability to control the secondary butterfly valves on the h22 intake manifold. if you plan on removing the valves anyway, just go with the P28 ecu.

 

you can control the butterflies with nitrous control on the s200.

though, apparently no one knows how to exactly do this.

just a matter of routing the 12v signal from the hondata to control the IM butterflies.

 

With the OBD1 ECU will I need a jumper to OBD2
