Does anyone disable dfco when logging data for tuning ve tables with vemaster???
(Oh yea-BTW; looks like my previous drive me crazy problems may have just been an intermittant sticking egr....gotta look to the simple things first...and thanks for all the suggestions)

I disable it while tuning in order to get a reading in the low load areas. You just need to watch out for when the pulse width gets close to 1.0-1.5 MS as the injectors can become unstable at that low of an on time.
