k. So i installed my setup that i've saved all my damn money for. i've want to do this for so long and finally got it done. well actually i have it all installed, just not tuned etc.

98 integra ls (b18b) with 90k on the clock. compression test results were 178 177 180 180 so the motor is perfectly healthy.

spoolin log
spooling 3" ac downpipe
spooling dumptube
-3an feed and -10 return
turbonetics t3/to4e 57 trim .63/.60
tial 38 @ 8psi
drag intercooler and piping
12:1 fmu
walbro 255

ya ok im sure you're gonna bash me for the fmu we all know they suck. i just planned on installing it to get it running and all the bugs worked out, then it'll be taken to locash in phoenix to be tuned on neptune. i have boosted a total of... maybe liek 12 times so far but driven it about 50 miles.

the 50 miles of driving were perfect -- nothing leaks (i really took my time installing everything and made sure everything was perfect.

BELOW ARE WHERE MY PROBLEMS START...

i took my buddies for the obligatory ride. i was driving at about 2500 rpm in 3rd gear for a few minutes to warm it up. suddenly i got a check engine light. its code 45. System Too Lean or Too Rich malfunction in the fuel monitoring systems

wtf is this? Can i drive my car back to my house so i can diagnose the problem? i drove the car about 5 miles after the check engine light came on and it drove perfectly still. no sputters, no hiccups, revved passed 3500 (drove it past that just to test if it was in limp mode, but not hard).

k thanks. oh and here's a camera phone pic of the intercooler

A car can run 12:1 afr's under vacuum w/o issues, and a narrow band o2 can't read anything richer than 13:1 accurately [with obd2 honda ecu's]. 16:1 or leaner and it will buck like a mechanical bull.

That'd be my guess - just too rich. I'd suggest you save another ~$300: $150 socketed obd1 ecu, $100 obd2-to-1 jumper harness, $50 'back alley' wideband tune/basemap. Without sticking a wideband sensor in there, you'll never really know. If you think that's too expensive, try buying a *good* b18b block, or rebuilding one for $300. Then try running it with the same 'tune' that killed the one before it.

i had that code once, couldnt figure it out for weeks. turned out there was enough gunk in my throttle bodythat it wouldnt let the flapper close all the way. sprayed some cleaner in there never happened again.

I'm not entirely sure what trips that code, although mine throws it every once in a while. I think it's got something to do with the computer logging the long term fuel trims, if the trims get too far out of whack to the positive (adding gas), it thinks the car is habitually running rich and will throw the code.

so basically its ok to drive, no biggy. and that the only real way i can fix it would be to convert to OBDI and run a custom program?

thanks for the responses guys
