Can CarPC Be Trusted?

For those who have been patient, ballsy, smart enough, and dumb enough, to dabble with T5 suite; do you use CarPC dashboard in conjunction with the realtime panel on T5 suite II. Obviously not at the same time, but, for example, I don't know how to retrieve specific rpm/MAP knock incidents from T5 SuiteII live panel, so I am forced to use CarPC, which has a nice graphical layout of where and at what pressure knock occurred. This is all well and good until one starts to mess with adaption data and fuel feedback, etc. I have found that CarPC routinely reports a lower AFR than T5 dash, by as much as 2AFR. Worse yet, I have found all the adaption data to be wrong, but to what extent I don't know. After disconnecting the battery for several hours, and writing a new flash to the ECU, CarPC reads 1.25 global fuel adaption~which is maxed out, as well as -1.0 ignition adapt. If you *change* the "maxed" fuel trim adaption, on a brand-new, phresh-out-the-box tune, the engine will stall for want of fuel.
Yes, I know workbin.bin must be the same bin as the one you flashed to the ECU on the bench (flash, not SRAM). For those experiencing similar problem, try going to program files->dilemma-->carPC control-->workbin.bin. But I digress
So, what program is the one you trust?
Sorry for the length.
Thanks in advance,
