Gen 4 Vipers have a pair of drive-by-wire throttle bodies - these were a new addition for the 2008-2010 cars. Up until that point, they had been cable operated. One of the major gripes about the Gen 4 cars is the utterly craptastic throttle response, and I'm trying to fix that.
We have these two tables available to deal with the throttle:
I've been adjusting the Pedal Percent Torque Request table with good results, but it is pretty tempermental if you adjust it too much...one step too far, and the car goes into limp mode, and that's no fun (it won't listen to any input at that point, spits and sputters everywhere...you have to pull over right then and there and shut it down). Any ideas what this table references to put it into limp mode? I'm getting to the point where I can tell if it is going to happen (the car bogs a bit usually), but I can't figure out why exactly it does it.
Any thoughts?
