There was indeed some headroom in vvti department , to swap slightly better mid range torque for slightly worse emissions due to less EGR. Glad you noticed that
how you (relearn) itSo at 2 in the morning, I decided to go out to the garage and install the new ECU. I jumped the OBD2 to let the ECU "learn" my keys for 30 minutes. Afterwards, pulled the jumper and gave it a go, and... It cranked right up! My girlfriend hopped in for a nice little night drive around the baron roads here in town.
First off, in the remapped "Normal" mode, improved throttle response and power is definitely noticeable. It feels very much like the stock "Power" mode, only a little fresher and a little meaner. You can certainly feel that there's a little more oomph and life present over the stock "Power" mode, and definitely considerably more than the stock "Normal" mode.
Speaking of the "Power" mode, that's the one where all the magic happens. Greatly improved throttle response, so much so that sometimes it's a bit touchy. If you're not careful, when you leave off from a light, you're liable to snap your neck. LOL Also, under moderate throttle input, once the car shifts into 2nd, it feels like the throttle is increased more, like stabbing the throttle again. A bit on the aggressive side. Odd, but doable.
Extra power?... Well it could be more of the effects of the increased throttle response, but it does in fact feel quicker in 1st through 3rd gear. Once you get past 80 mph, it really doesn't feel much different from stock. Maybe there's a little extra oomph there, but it's hard to tell via butt dyno. There's definitely seems to be more torque, especially in the sub-60 mph range, which is nice and is perfect for city driving.
Lastly, in "Power" mode, up-shifts are improved. Not only are they quicker, you can also feel them. Down-shifts are also quicker and sharper. Not drastically so, but again, noticeable.
All in all, for the little bit of money spent, it's a good upgrade and I would do it again. I would say it's worth the money... Short of doing a full stand-alone computer.
And just because, a few pics...

how you (relearn) it
Sounds frikken epic bro. Can you post an acceleration video of your speedo after the remap pleaseI sure did notice, and do on a daily basis.
BTW George, I was going to send you an email with a little "review" of the remapped ECU, but since I saw you respond here I didn't see the point of doubling up on you with it.
One more thing I've noticed with the remapped ECU... Before in stock form, when doing light throttle input in city traffic, the transmission would shift from 3rd straight to 5th gear, only being in 4th for a brief moment, only to kick back down to 4th because of the needed torque to accelerate, even at a slow rate. And once in 5th gear, if you depressed the throttle slightly to accelerate a little, it would kick down into 4th.
NOW, with the remapped ECU, it goes through every gear as it should, and once in 5th and you depress the throttle, it stays in 5th and just moves. On the way home this morning from work, I tested it to see how hard I could push it before it down-shifted. I was able to accelerate from 50 mph to 60 mph in about 5 seconds or so while staying in 5th gear, and that was with a lot more throttle input than before. If I gave it that much throttle in stock form, it would have kicked down into 4th, maybe even 3rd for a moment.
The more I drive my car, the more things I notice with this remapped ECU. It's making me love this car even more!
And on a totally unrelated subject, my engine has always had a very slight pinging issue under hard acceleration, something that I had hope would go away once I had the car a while, taking it on long road trips and putting top tier 93 octane gas in it, but nothing has changed. Doing a little research, it seems that the engine temp sensor could be the culprit, so I ordered a genuine Toyota water sensor a couple days ago, and it showed up yesterday. So I know what I'll be doing on my next day off. I'm hoping it fixes it.
Things are the other way around this time.
