My car is too eager to switch to open loop
I've had my scangauge for a few weeks now, and I've noticed a few undesirable things my engine management computer does, especially when it's cold.
Most annoying is the very high idle until it warms up. I show an open loop idle, 1500 rpm, and 1gph for the first minute or two of driving. Once it gets vaguely warm, I see open loop, 1000 rpm, 0.50gph. This is still not as desirable as the closed loop, 500rpm, 0.25gph that I've come to expect. I often see the 0.50gph idle with the coolant temp at 195°F while I'm trying to pulse and glide. I run 0W30, so I'm confident it can idle lower especially while it's cold. Can I force it into closed loop idle?
There's a seperate issue: whenever I open my throttle more than, say, 1/3, it goes into open loop. Yeah, I know, welcome to the real world. Still, can I keep closed loop for slightly larger throttle aperatures? What if I mod the TPS?
