KD93R1 Posted November 13, 2010 Report Share Posted November 13, 2010 Project today, dyno tune car. This is my 3rd trip to the dyno. Came really close to gettin it right today except we could not get the AFR to come up no matter what? Laptop software would not do it? Car seems to run fine once you start rolling but is extremely rich at idle and low rpm, non spirited driving. My Autometer AFR guage usually reads in the low to mid 10's at idle and low rpm driving. Its funny because I can be driving normal, low rpms and the AFR is nice, like 14's t0 15's and as I am driving, without changing throttle position, just cruisin the AFR starts going back to the 10's and 11's? Think I need to clean out my wastegate too. It is really carbon'd up especially w/the car running so rich (seperate issue). Also, dyno sensors confirm very rich conditions and its numbers are right on w/my guage. I guess to much is better than not enough, but this is a little to much. http://i1039.photobucket.com/albums/a473/KD93R1PB/th_007-3.jpg Quote Link to comment Share on other sites More sharing options...
