I am trying to research into this but not sure I found what would relate directly to my current issue apart from maybe the possibly obvious.
When I am driving along and release the throttle, I find that the car does not want to naturally decelerate very much when slowing without brakes.
My guess: Could this have something to do with the throttle follower and cracker tables? I am leaning towards it probably is receiving a little too much airflow after the TB closed while coasting?
This is where i plan to do a little logging on and see what I am getting here.
What typical approx MAP pressures should I be seeing in an A4 with a cam in the 228 range with LSA of 112 deg. 0% TPS decel at a VSS of 60-0kph?
Is it possible it is related to the desired idle which is currently set at 1000rpm which is a tad too high for my liking.
I plan to set the 'desired idle' to about 870rpm - 900rpm and see if this makes any difference while decelerating then look further into the issue if that fails.
If anyone can clarify where I should start out and what tables i may need to investigate, this would be greatly appreciated as I am 'very' new to it all so not quite sure if I am on the money or not with this one yet. ;)
If there is anything I have missed, please let me know.
Thanks
