if i use a p13 ecu on an h23, how will it affect the motor? if i deos affect it, how long before i start to see, feel, or hear the damage?

 

The fuel map is different - you'll most likely get a cel code for your injectors, but it should work temporarily. I used my p14 on an H22 for a couple days, threw the code at higher speeds.

If you need a p14, I have my old one here.

 

im only goin to use it for a weeks untill i get a p14, unless ur willing to donate urs?
