I ordered mine, and very excited about it!! Unfortunately, very new to tuning...So do I unplug this device before a service at the Dealership, everytime to prevent voiding warranties? Is it easy to unplug and plug right back in, easy to use for someone slow, like myself, change anything mechanical..etc.?! LoL Ty in advance ^^
I feel dumb for asking, but I'm not quite sure what the next step is. I see the OBD end, and other end with a mini USB looks like I need to go get a windows laptop. Once I plug into the car and a laptop, what's next? There's no instructions
@ sheddy, @ flash5... I appreciate you both responding to my pm's. The HPS intake is a night and day difference, car seems to climb rpms quicker and I see I'm hitting the +5 bar much more quicker. HPS tube is also bigger then stock intake tube. The $190 was worth it.
Here's a timetable of what I've done so far with regards to the OV Tune:
03/12 - Ordered with discount code
03/18 - Was sent instructions (same Tacoma one posted above)
03/18 - Downloaded p5flash.exe, read my computer's System ID, e-mailed System ID to OV
03/19 - E-mailed back Windows registry key to apply to my computer. Note that because of this, virtual Windows OSs running on Mac or Linux is not recommended
03/19 - Identified my vehicle (NX) ECU and e-mailed the readout to OV. It looks like this:
Interface: Tactrix Inc. - OpenPort 2.0 J2534 ISO/CAN/VPW/PWM
DLL: 1.02.4791 Jun 2 2016 12:43:17
Firmware: 1.17.4877
08:32:30 Identification
Calibration: 896637813200
Calibration file: 89663-78132
Part Number: 89661-78130
08:32:30 Completed successfully
Unlike PCMFlash used for the TTi tune, p5flash didn't provide any readout for TCU information. Because of this, I also e-mailed the original ECU and TCU bin file dumps that PCMFlash created way back when I was about to start with the TTi tune.
03/24 (today) - Still waiting on the tuned file(s)
Now, to while away the time and to amuse myself, I removed the TTi tune and flashed the ECU back to original settings. TCU remained tuned. The power difference is so apparent it's hilarious. If you guys are familiar with how a brake pedal feels spongy as a result of air in your brake lines, then you'll get it when I say it "feels" like the accelerator line had air in it IF IT EVER WERE HYDRAULIC.
Where the TTi tune would have get up and go, the factory tune just doesn't release power until you're about 80% on the accelerator. It just feels like you're in Eco mode all the time. Those familiar with ECU tuning might say that this is simply a result of altering the pedal % vs requested torque value table of the tune, but TTi really did work on improving actual engine performance, and this is apparent when comparing the factory vs TTi performance when the accelerator pedal is maxed out, specially in the 3000-4000 rpm area. I recall taking the NX to a track before the tune (yes, yes, I know) and being frustrated by the engine's lack of mid-range power during corner exits in the track's more technical sections. This was made worse by the 6 speed's gap between 1st and 2nd. 2nd was at 2800rpm, yet the ECU wouldn't allow downshifting into 1st. There was no choice but to wait zzzzz
Much has been said about the throttle response delay of the 200t engines, and going back to the factory tune made this even more apparent. To TTi's credit, they were able to reduce this delay, just not fully eliminate it. Unexpectedly, the engine sounds and runs a lot smoother on the factory tune, so we'll have to give Toyota some credit for that.
Now to wait for the OV tune.
Here's some conservative driving, with a few spurts here and there, shot last Christmas day. You could just live in the mid-range with the TTi tune. This was my first time out with the Jeep active rear bump stops in place of the NX's factory rear bumpstops. They're not in contact during normal driving but quickly ramp up in spring rate when loaded, inducing rotation the more you load the outside rear in a corner (mid-corner and exit).

Glad to hear you went with HPS! They have a great charge pipe! It allows great airflow to the engine than the smaller restrictive OEM pipe. Unfortunately dyno proven to only add an extra 6 whp and 7 Ft-Ibs of torque. But don’t have to worry about heat soak. Going to be trying out there actual Air-Intake kit which supposedly adds 22 horsepower after I flash my OV Tune. Previously owned Injen Air Intake and AEM. Will compare all 4 after.
Before I take the plunge and get the OV Tune. Are the tunes available for all Stages OV listed in their post. I think it went up to Stage 3/4 depending what mods you have on the car. Also will I be able to reflash it back to factory tune when I take it to the dealership?
