The stock Toyo ECU looks at those three points as "trigger" values for learning processes of fuel trims. Idle is first and usually takes about 45-60 seconds of idling even off of cold start to begin evaluating the learning process.
In short, all 3 positions, per several Toyo Engineers are important.

Imagine what a lowly Atom CPU with 1G ram and 16GB of SSD storage could do for a ECU/stand-alone/piggy. But that's the easy part, that's what I know, the hardware... Writing the firmware/software is another matter entirely.

I don't know if my XB2 ECU is that different from the TC's or if the difference is OBD1 vs OBD2 but even on the coldest days my ECU enters CL as soon as the primary O2 sensor warms up (~1 minute). Even then, my cold engine fuel trims are very different from my hot engine trims. It seems to me that the ECU uses different fuel tables or makes adjustments when cold vs hot. That might explain why a CL cold idle FT of -15% becomes +15% when hot. Then again, it could be caused by other factors as well. I'm unsure. I know what I've seen and data logged but am still working out the cause and effect.
I'm sorry I didn't realize it was you that I spoke with the other day. NP on not getting back to me before and I understand why you would want to do the testing in-house. I'm not exactly close by and any problems would have to be handled by phone calls and emails. But if you guys ever change your minds, I'd be very happy to test the X-1 on my XB2. The X-1 is what a piggyback should be and not like the weak piggyhacks currently available for Toyotas.

I realize the potential market is small compared to the TC but if you guys were to offer a X-1 version for the XB2 I believe it would also work with the Corolla and Rav4. Hopefully all it would take is a new harness and some testing.

Thanks Paul. That makes perfect sense to me.

A few people have asked about this unit and emissions. Let me clarify that it CAN pass a plug-in emissions test pending that your calibration is logical just like an AEM FIC, E-manage and E-manage Ultimate. What I mean is that if it's not excessively rich or lean, does not have any O2 codes, knock etc.
The OBD port is still active and the ECU still throws codes. ALSO, make sure your fuel trims are in line! No more than -5 LTFT

another question, will this unit come with a start up calibration? base map? if so how? or should we treat it like a standalone, ie tuner starts from scratch.
the promise of an oem turbo'ed feel of this unit, without going standalone is really what im after.
itll be my first time to get a kit, im not going for some insane numbers just fun daily driver and i want to do it right and be done with it. cheers

I just got this unit. The setup is T3 turbo (hoping to upgrade sometime soon), 700cc injectors, water/meth injection, built engine. I will let you all know how it turns out. Dezod just took my order for this unit on Thursday, i think. So hopefully i will be driving my car in about a moth- month and a half.

I won't argue with that! Thanks for the info. Now if only I had a piggyback that could work in unison with the infinitely more advanced factory ECU instead of one that can only modify ECU input sensors and crudely control the fuel injector pulse duration...

It's all good!
Yes Sir they did. The AEM EMS is cool would have loved to see how fine tuned Taylor could have gotten it. That is over some sessions of tuning. I just need "more emissions friendly equipment", as you said. I'm hoping that i can still get crazy with the TC. You know, bigger turbo and so on. Thanks by the way. I have gotten a few parts from ya'lls store.
