I run my tablet w/ Torque Pro every time I drive my truck. It's never had any
problems (see note) with it not setting the EVAP, CAT, etc. readiness monitors not setting after a battery pull. You need to drive it under the right driving parameters. The ECU is very picky and if you go out the parameter settings (i.e. speed), then you will need to do it all over again till it's right. If it's taking forever for the monitors to set. Either, you aren't driving in the right parameters. Or you have an old (lazy) O2 sensor that is on it's way out. Buying a new one should help it set faster. The worst case is your CAT is clogged up and it will take a lot of attempts to set it. Otherwise, get yourself a new CAT.
Note: It took me nearly 2 weeks to set my monitors the last time I cleared my ECU. I don't daily my 80 and it's hard to hit the right driving parameters in my area because of all the traffic. I usually have the best luck at night time (10pm+) when there's limited traffic where I can stay in the MPH range and not piss anyone off behind me and hold up traffic. Everything on my truck is new except for the original cat at 190k. I know it's near the end of life and restricting my exhaust causes me not to achieve full boost. I want to buy magaflow cats eventually. The readiness codes do set but it takes forever. Getting a new CATs should reduce the time it takes to set.
I have the DP blanket.
Edit: here's a website I googled for the driving parameters. Here's a thread from MUD too for readiness monitors.

Hi Folks, So I took my LX in for Colorado emissions a couple weeks ago. To my surprise, they did not put it on the rollers (I assume they must have decided 315's are too big?). When this is the case, they just check your ecu for "readiness"- basically if the ecu is communicating through the...
