Here's what I'm working with...


I have a Fully built B16, built for boost. Compression is 175psi all the way across, was told it probably yields me around 9.0:1 compression. I also have a b16 tranny but rarely do Interstate driving.



Recently, I just re-wired my o2 sensor back up but I have a feeling that, it is burnt up either way because it used to be on a Chipped LS ecu that used to drink fuel. VTEC also isn't engaging (more than likely a crossed wire, still working out the bugs in this car)


I seriously get like no more than 87-95 miles to the tank.

CRX si's have the 11.9 gallon tank.

Somethings wrong, Ideas? I also have fresh LASER Iridium Spark plugs in it.

 

I am shooting two codes on my ECU though.

3?
and 14-IAC (typical damn honda)

 

3 is BAD GAS MILEAGE

 

Hahaha, seriously. I've looked everywhere for that code and I can't find it. If I recall correctly, the OBD-0 pr3 needs a secondary o2 sensor and I think thats the code its shooting.

 

Also, when I let off the gas at times..It will "pop and sometimes sound like a .22 caliber gun"

 

get a tune.

 

Sounds like your running really rich and thats the backfiring at least

 

Well, I knew that already. I was just trying to give a better description.

 

What size injectors?

 

They're stock injectors, Walbro 255lph fuel pump and a fuel pressure regulator. It used to have 550's in it, but I don't have a turbo kit on so I took them out.
