Is it normal for Gen 4 Ecus to run rich for 10 minutes after a flash even in open loop? I started a Maf tune on my car yesterday, set up to only use MAF and set all the afr correction tables to all 1's. Seems as if everytime I flash a new tune it runs about two points rich for 10-15 minutes and it slowly leans itself out to where it should be.
Am I missing something or is this normal? I'll post my tune file for reference. (DUSTIN)-maftune1b.hptThanks.
