R18 civic w/small turbo kit goes mega rich under boost

Post by wiggum80 » Fri May 04, 2012 11:38 am

2009 Civic with R18 turbocharged. All is well until boost, when it crosses over from the last vacuum column it goes 10.0AFR no matter how much fuel I remove. Any ideas or suggestions will be much appreciated.

You have a lot of error codes. Resolve those then see if the problem goes away.

Hmm.. well I cleared the codes and drove the car for 2 days back and forth from work. I didn't go into boost and the mil light didn't come on at all. As soon as it sees boost I get MAF malfunction code and system too rich code. Any suggestions as to what step I should take next? Any direction is much appreciated, thanks for looking at the datalogs.

I had the same problem, I had this problem because the MAF was to close to the fans and when they went on i got the malfunction, I changed to map based tuning and moved the MAF after the intercooler and this fixed it
