Knock sensor/ IAT
ok so i was putting a turbo kit on a 2000 si (b16a2) today and broke what i believe is the knock sensor and also the piping for the turbo didnt come with the hole for the IAT sensor so im wondering would that cause bogging while driving and a fluctuating / high idle?
Any help would be great,
thanks
The knock sensor will throw the computer into limp mode... knock sensors r not CHEAP! G/L

yep. limp mode and about $90 for a new one.Originally Posted by DB4LYFE ™
my problem right now, get ur comp chiped, scotty can dleet the knocks for 85. and if u buy a sensor than dont buy the cheep one get the oem i have broken a few just by engin vib.
i would NOT "delete" your knock sensor. its your protection device against detonation.
limp mode means it wont be past 3k right?
price isnt really a concern just need it running right...
got a chipped and socketed p28
yea! in some cases..

ok cause it hits like 3k and almost bounces/bogs of the limiter it seems like...
yea......

anyone have any input on the IAT?
i vote IAT. i dont think you can even get to the knock sensor with just intercooler piping, let alone break it
Installed... Iat sensor in piping still got a flucuating idle so im thinkin i missed a vacuum line somewhere
odds are
when i adjust the idle screw it shows no improvement either way i turn it. Checked all vacuum lines they seem to be ok im sooooo lost
it"ll be ok as long as it's chipped/tuned. honda knock sensors detect a lot of false knock anyway. there are plenty of them out there w/o knock sensors.
are there aftermarket inj or the stock ones installed? any cel? how many and what are they?

A P28 doesn't look for a knock sensor anyway... I can't remember if it uses the IAT sensor or not but if it does then the IAT needs to be in place because it works directly with your fuel and timing maps. I would check your map sensor and fuel pressure.. Also what is the P28 tuned for?

if the knock is enabled on a chipped p28 it'll throw the cel right away since it doesn't have the circuitry for knock.
they do have iat and you are correct that it needs to be plumbed into the intake or intake tube so the enrichment tables will do their job as nec.

I've seen people put the IAT sensor on the intake/filter side of the turbo. As Scotty (?) said it needs to be in the actually charge tube after the intercooler or in the intake manifold itself, this way it reads actual Air temp going into the engine not cool air going into the turbo. On alot of fords the IAT is made into the Mass Air Sensor, we would add an actual sensor as stated above so we could tune properly.
yep...meant charge tube not actual intake tube of turbo. i preferr the intake runner or plenum personally if you have that option.
