Alright i curently have a h22a in my accord that has a warped crankshaft...got a h22a4 and what all do i have to take off my h22a for the h22a4 to work?? both motors are obd2 but im running obd1 ecu..i knw my harness stays, distributor, what else do i have to change?? or is that it?? let me know please

 

Is the H22A4 coming complete? If it is then there is no need to swap any of your OBD2 H22A sensors. Both blocks are OBD2 then they will have the same sensors on them. Test them all with a multimeter, and take the ones that work to spec and are in the best shape.

If your staying OBD2 with all your wiring and running an OBD2 to OBD1 ECU conversion harness that should be all you need.

 

well im not running a jumper harness my harness is a, accord wired for the h22 does this make a differance what about fuel injectors will the obd2 injectors work?

 

What injectors are you using? There are a few possible sizes and types.

High impedance, Saturated 280cc (11-13ohms of resistance) (97+)
Low impedance, Peak & Hold 345cc (2-3ohms of resistance) (92-96)

• If they are low impudence then they should work fine with the stock Accord resistor box.
• If they are saturated you will need to remove the Accord resistor box.

 

how do you tell if they are low impudence or saturated?? i know the injectors that i have in there right now are 310cc and the stock accord resistor box is in there

 

Use a multimeter and measure the resistance between the the two contacts on the injector.

Low impedance, Peak & Hold will read 2-3 ohms of resistance.
High impedance, Saturated will read 11-13 ohms of resistance.

What 310cc injectors are you using. RC, or Precision?

The only 310cc injectors that I've found are saturated and do not require a resistor box.

 

ill check tommarow when i go to the shop..i dont have a clue thats what my buddy said that he put in there before i got the car i see if they are peak & hold or saturated
