The P39 does not need a knock sensor. Same with the PT3 and PT6 from USDM accords. P39 is over-priced and I can tell you from personal experience it won't make the motor run any better than the PT3 or 6, or the the stock P14 with a knock sensor installed on your F22b.

Lots of options here, but if you want the P39 get your checkbook out.

 

Ok, So If I Dont Need A Knock Sensor Then I Can Do The Swap And Not Have To Worry Bout Any Lights Coming On Bout A Knock Sensor Or anything In That Matter? I Read Alot Of Forums Bout People Needing Them Or Having Problems With A Knock Sensor....I Got Told When I Was Gunna Put A H23A1 in my car id have to install a knock sensor?......jus tryin to get the help I need.




Thanks For Everyones Help And Time!

 

yes H23A1 ECU needs KS for proper work.

 

If your worried about engine lights get a pt3 ecu from a usdm accord. They are 30-50 dollars compared to the 150+ for the p39 ecu, or knock sensor.

I drove my f22b on my p14 from the prelude for months with no troubles. The knock sensor went bad quickly, and I always had a light on. I put the pt3 in and the light went out, but the performance was the same.

Taking it further when I put a f22b ecu in the performance was the same.

In my opinion the pt3 is just perfect considering the price, and lack of knock sensor circuit.

 

I ran my F22B on the p14 ... just welded a bolt on the block and threaded the knock sensor in ... never had any problems with the knock sensor after that

motor blew from over reving tho haha ...
