whats up guys. so here is my deal, i have a 92 prelude i just threw a jdm h22 in there, and swapped out the h23. my car has been down for 10 months now and i dont know whats wrong. i think when installing it i blew my ecu when i had a main harness was connected incorrectly.

my questions right now are...is there any easy way to check my ecu, to see if it is totally fucked or not?
if i were to plug it into my friends car who has an h22 swap, could i damage anything on his car if my ecu doesnt work? (...also he has a manuel trans, i have auto)

ps-anyone in the west chester pa area, if u can get my car running ill give u $300 cash
