What about the blue one and then have your tuner adj for the slight retard of timing it causes. I know a number of people have posted good results from using it.
When I went in for the cruse control recall and made it very clear not to touch anything else. I got it back with what I thought was only the fixed CC
. I knew something was up as it was running dif. Checked ( a few hours later now) and sure enough they had swapped it. Went back as soon as they reopened and asked what part of DO NOT TOUCH ANY OTHER SYSTEMS OR PARTS they did not understand. Well they had already thrown it out and now I have a CPS
that some how is getting me 3 mpg
worse gas mile and slower throttle response. They offered to reflash the PCM
to the latest one thinking it might help. Now my tranny shifts are worse and is louder some how. But of course when I go back a hour later after test driving it they could not flash it back to the old version. Got love Fords engineers that design these things. They sure seem to know there stuff
It sure was one way to make sure I went to aftermarket to get it to run right. I am thinking of trying the blue CPS
to see how it runs with it. At worse I have one for an emergency but they do cost considerably more than the practically free grey ones.
As this applies to the OPS question can you tuners adj tuning to account for the negative changes some of these CPS
cause. What about from the retarded timing the blue CPS
causes? Would going to a different PCM
from a different family have any effect? I know I have seen a number of posts stating certain version and family codes are better or worse than others. What is the best one over all to use?
