Hello there have tried most of the obd2 apps on the market and Car Gauge Pro is one of the better ones and am enjoying experimenting with it. I do have one query right now.While using the Live Data section of the app on my 2002 Toyota Avensis 1zz-fe that's the 129bhp 1794 cc vvti engine I've notice regularly that Fuel System 1 & 2 will start in Open Loop as tou'dd expect going into Closed Loop fairly quickly,, like it should and then switch between the two depending on the demands on the engine at the time. What is unusual is at certain times more so that others it goes into Open Loop - Drive. I've been playing about with both engine management systems for a good few years now and this is the first time I've heard any reference to Open Loop Drive. Have not heard of it in anything I've ever read or coming up on any Scan Tool or app so I was hoping for some info on it. I know what I suspect it is but I'd rather hear for sure.
