APEXi Smart Accel Controller: Weigh-In If Installed (Merged Threads)

I just installed mine today and am not sure it is working correctly. I went through the calibration/initialization settings as described in the manual and everything appears to have worked as expected. That said, I didn't notice much difference, if any, on my test drive. I can cycle through all the colors but they never blink. From what I can gather, blinking means it is working in all modes except red. None of my colors blink. Maybe it is working and I just expected a more pronounced difference based on the feedback in this post?
Any suggestions?

Red is only 1 throttle mode and other throttle modes will not flash. Only boost modes flash so put in in purple, floor it where you can and look for the flash. To be honest, you wont even need to look at the flash, for me it was definitely noticeable. Not power wise and its not a power mod but the throttle response is chalk and cheese (to me anyway).
Try to recalibrate (ive replied to someone else earlier with step by step in case you missed 1 step). They are very reliable units so doubt its the controller itself.

Well you got power so sounds like a calibration / setup issue. Possibly disconnect it (power source), reconnect and try the calibration again
Press ignition twice but dont turn on the engine. Just have the car electrics working. The apexi button should be flashing white
2. Press the bottom of the switch and hold it until it turns blue
3. once you release the button it will go from blue to flashing whtie again
4. depress the accelerator pedal all the way and press the top of the button at the same time until it turns red
5. Once red, release the button and accelerator pedal
6. Fingers crossed there will be no more flashing on the button meaning youre good to go
FYI for anyone who wants it always on....
Press and hold top of the button whilst pressing push start to acc then ign. My button flashed white 4 times. Tested it and it remains in boost purple mode which is what I'm using.
Weird thing is instructions says press bottom of the button and it will flash twice. For me it flashed 4 times but didn't remain on so experimented the other way and success.

If you run in Purple mode the light will blink as long as you're making larger than minute changes to the pedal angle. If you pick a position and hold it, the modulator will time out and bring the throttle back to 1:1 modulation.
Honestly the easiest way to know you calibrated it correctly is put it in Dark Blue, put the car in Eco, then drive. Push the pedal to the floor and enjoy the slowness. Which, by the way, will keep the car under 50% throttle or so for several seconds so even if you're on the interstate you won't get a sudden surge in power for passing

If the light is blinking, for instance in Purple mode when you modulate the pedal, it's working. What it's doing is (for a short duration) cracking the throttle open wider than you actually moved the pedal (scaling) to give you a peppier response than you could normally get out of the pedal sensor with your foot. And that's all it does. Red mode just takes the linear actuation and applies an aggressive curve to 100%, green mode takes a gentle approach and down-modulates the input to 100%.

Ive never come across a video, but this guy from the UK Lexus forums has a detailed pic by pic and write up about how to install it. Relatively straight forward

Even half throttle and pressing the red mode, you can feel the throttle liven up instantly. Its not a miracle device that adds more power as such but you can definitely feel its responsiveness, well i could. WOT gotta love the purple, definitely kicks down hard and agressively especially with Sports mode on too.

My controller has run into an issue over the past several days- it just won't stay calibrated. I'll have it on, turn off the car, add gas, turn the car back on and...poof. White light of amnesia. It's not hard to recalibrate, just super annoying. Sometimes when it goes white at startup it starts flashing rapidly, other times, just solid. Either way have to turn the car off, let it time out, then recal.
Also, if I idle for an extended time period, it gets amnesia.

Somebody ought to take him up on this, I LOVE Mine! It doesn't add any extra HP but makes a BIG Difference in the cars acceleration, even if you're at a red light & not paying attention & leave when it turns green it's very Easy to spin out. The car is sooooooooo much more Jumpy & Jerky if you're not careful (I usually keep mine in Purple Mode, it & Red are my favorites). I was like most everybody else before I bought mine thinking the same things, but I promise you it makes a Huge difference!

Have you retraced the install, checked all connections, pin connection around the right way. Normally you'd get check VSC etc if the conneciton is back to front but could be somewhere else along the install
