hello thanks for helping,

i have a 91 crx si converted to obd1 w/ a bard b16a and i bought a ls vtec off a buddy who had it in his drag car made 232 whp w/o nitrous. i have the new motor in but i see that there is no knock sensor? what would the best/ easiest thing to do about it?

 

i would delete it in the ecu esiest way or tap the block and put a knock sensor

 

Just run a p28 or hondata if you don't want to tap the block.

 

should of used the b18A1 block instead then they come with knock sensors, just delete it and get a good tune

 

it is a b18a1 block but i didn't see any knock sensor

 

isnt it next to the oil pressure sensor by the alternator then? ( 92-93 block's /obd1 have temp/FAN switch by the radiator hose Neck by the Dizzy instead of the back of the block like the 90-91 b18a1's) a green round one? or maybe obd-0 integra 90-91 b18a1 didnt have knock sensors?? Im not sure on this now maybe only obd1 had knock sensors

 

use one of the alternator bracket holes,

Using a 10.9 mm drill bit, opened up the hole on the bracket and the block. Then carefully tap the hole with a 12 mm x 1.25 thread pitch tap. Be sure to clean up the shavings and then screw the knock sensor. This will keep your ECU from throwing any codes ( taken from C-speed)

 

SO WATS UNDER THAT COVER U HAVE LOL

 

Yea jus delete it from the ECU YOULL BE GOOD !

 

Crazyyy 16:1 compression . going to run E85 and a shot of nazzzz


just kidding.

I took the pictures from C-speed.

 

ok thanks

 

so if i have a p28 it dosent look for the knock?

 

It wont look for knock if you tell it not to. Just run Hondata s200 or even 100 and it'll allow you to delete the knock sensor as a whole.

 

ok if i have a p28 is it going to look for the knock or do i have to chip it? thanks

 

If you run the p28 you'll have to chip and tune it regardless.
