ALright well I have a 93 hb civic with a jdm h22a. Me and my buddys just installed a bolt on max rev turbo kit. Then it started reading 3 codes. 10, 12, 23. I checked them out I i think they are air intake temp, egr, and knock. I had none of those codes before and my egr has never even been hooked up cause supposedly my ecu is not even supposed to read egr. We installed a vortec fmu and i have walbro fuel pump. If I drive the car nice it drives fine, I can gradually give it gas and i can hear and feel it spool. If i give it more gas it dumps out the wastegate and then boggs and i have no power. Helpp PLease

 

bump

 

i know someone here knows the awnser it ran fine allmotor now turboed it is throwing egr knock and iat but iwth another friends usdm p13 it is throwing o2 sensor it doesn't make sense

 

Well if you were running a ecu before that did not read those sensors you may get the codes that may be your problem. I think your knock sensor may cause you car to run like *** but I am not sure on teh intake air temp and the egr will not hurt anything it will just give you a engine light

 

See its weird cause before it was turboed I used my stock p13 and it only ran a code 36 which is traction control. Now after turboed, that same ecu is readen those 3 codes all of a sudden. The egr has never been hooked up and the knock secor was put in kinda recently. With my friends usdm p13 it reads o2 and egr. And on my other friends ecu it only read 1 code and it was a vtec code. Its just weird to me.

 

bump i know some one knows the awnser or a way to get around this

 

bump cause i have no idea whats wrong with that car .. someone help this poor helpless soul

 

Can't you just put a block plate on the EGR to get rid of one of those codes?

 

hmmm...sounds like the same problem my friend is having....

 

i don't think blocking off the egr will get rid of the code because it isn't even hooked up, but i might be wrong.
and to dream i wonder why it sounds like someone you know too

 

yep the knock sensor can make ur car run like poopy if there is something wrong with it or if u are actually have detonation problems.

i have no idea why the egr just came on, or why u have a problemm with the iat.

to cure ur waste gate problem double check ur vacums lines, make sure it has sufficent vaccum.

just some thought and hope they help.
