can u tell any differnce in the H22 vtec ecu and the H23 not vtec ecu by just looking at them.. i think my cars running liek shit because the guy i baught it from got the motor from the junkyard and put the wrong ecu in it but im not too sure

 

Look at the sticker on top or on the side of the ecu. In the middle will be a letter and then two numbers it should read P14 for H23 and P13 for H22. u cant tell just by glancing at it!

 

By the way if you need a P13 OBD1 I have a JDM P13 i am selling! It is on ebay for $75 and no one has bidded on it yet. i got it when i bought my engine and i am getting a Spoon ecu so i dont need this one. It only has 1 day and like 10 hours left. check it out!
