I'm having an issue where my motor doesn't always return to idle in a consistent fashion. For example, sometimes if I pull up to a stop light the rpm's will drop down to about 1350, whereas other times it will drop down to about 1100 (where I want idle to be.) Usually, if the idle doesn't drop all the way down but I give the throttle a quick blip, it will usually then drop down to 1100-ish. However, when looking in Tuner Studio or in MegaLog Viewer it will always show the TPS position as zero while at idle. What I'm trying to figure out if this is a tuning issue, or rather, if the throttle plate is just not quite shutting but the output signal from the TPS is low enough that the software is rounding the number down to zero.
So, based on the above, I'm trying to figure out if there is a way to get better granularity into what the TPS reading is (for example, could I get the number down to two decimal points.) Anybody know if this is doable?
