Where Can I get the chip or how do I modify the TPS to get rid of the shift retard? Thanks
You can't modify the tps to kill the tip in retard.........and this is why.
Ford uses the words "tip in" to mean....... mash the throttle, lol.
While this spark retard is present during a normal wot shift it is more than that and here is an example of another way this spark retard will come into play when you drive your car.
If you are at say 2500rpm in 3rd gear at a steady cruise which would be at light throttle and then "tip in" the throttle to the floor the pcm will retard the spark cause it saw you take the tps from say 1/4 to wot.
On a stock GT or Cobra pcm the spark table commands 22*@2500rpm@wot. You can add to that value the additional spark you haved dialed in with the dizzy that is above 10* for a more accurate value if you wish. Say you got 16* at the dizzy so in this case you would have a spark value of about 28*@ 2500rpm under wot conditions.
However
With our little example above the pcm sees you mat the skinny pedal and envokes the SPARK MINIMUM FOR TIP IN RETARD on your stock pcm. The value for this spark retard is 5* so at this point in time your commanded spark value has gone from 28* to 5*.
Been a while since I've seen this in my data logs but I wanna say the retard was present for 2 to 4 data events. I think I remember someone saying you get about 10 to 12 events per second. Would not that be about 1/4 to 1/3 of a second you have this retard present?
The spark shift retard Paul talked about is something that can really make a difference if you can adjust it, but you gotta get in the pcm to do it.
btw.....does this kind of stuff make sense to you guys
and
do you guys want me to share this kind of stuff or should I just blow it off, lol
Later
