I'm running a 5.7 with a 274 Cam 2.9 Whipple with 10lb boost. I'm trying to figure out the tables to increase the deceleration rate. When I let off of the gas the deceleration rate is very slow. Doesn?t actually run like cruise control but it's kind of like feathering the pedal to slow down very gradually.
Do I need to adjust the numbers within table 35101 Desired TQ Minimum FW Tq?
UPDATE:
Almost a year to the day later I have some good updates to post on this one.
I recently went through the process of working through disabling the decel fuel cutoff as I had issues with bucking. I started out with almost zero deceleration and I ended up with throttle hang with the clutch in/in neutral in a specific RPM range. I was able to dial that out using the friction loss table. I was actually able to dial in my overall deceleration rate, I now have a nice smooth transition from coast back to acceleration and a good deceleration rate. Also if you are having issues with the car stalling after say a rev then going back to idle this area will help with that as well. I have a bigger cam so you will notice in the idle rpm area I have it bumped up again in the lowest RPM range to catch the rpm without stumble or stall. One more point to mention, I had to drop the numbers above where I had the throttle hang for it to level out properly. I ended up smoothing out the transition with the needed drop for my trouble zone above and below the range. Attached is stock vs. updated. I haven't tried it yet but I assume this will address the 10 minute return to idle from a rev on the 5.7.
