I have a 94 accord ex and wanted to do a h22 swap. I needed to know if I get an h22,OBD 1, could I use My ecu or will I have to get a new ecu?

you can use your ecu however by using ur stock ecu i don't think the redline will match up so your ecu will give the motor the same redline as your stock motor... Best thing to do is just fork over the 200-300 for a prelude ecu i think the obd I is the P13 if i'm not mistaken...

 

NO don't use your Accord ECU, fuel maps as well as redline is different. Go out and get the correct ECU. Look here and on Ebay as well as other forum sites for a P13, you may get lucky I got mine for $140.

 

u can also use a p13 AUTo ecu as well for an OBD1 h22 if im not mistaken, they both work fine but the auto ecu will throw a code but thats for an auto so no worries

 

Can you use the accord ECU? Yes, but why. The car will start but won't drive like it's supposed to.

Get a P13, or Hondata with P28, or P72.

The ECU you have now is designed for a SOHC, the H22 is a DOHC. And there are other differences.
