OK. So I did a little test run tonight. It's good, but not as great as I had hoped. Again, I want to drive it in normal mode more than sport because I do a lot of city driving. The response in normal is better, but there were times when there's still a lag, mainly in the higher gears I think. I got a little tire spin with a light push on the pedal from stop. That never happened before the install. But at higher speeds (around 35-40), there is a noticeable lag.

I'll know more tomorrow when I take it for a longer drive. But so far, I would say 7/10. Maybe this will change tomorrow.

As for the snow/wet mode, yes, it's not the same. I would say that the snow/wet mode now is a little less than how the normal mode use to be. The throttle response is a little slower than how normal use to be. If you put in the chip that lessens the response to 60 percent, I think it should be fine.
Any lag you perceive now is just a function of automatic transmission downshifting slowly. In normal mode, the auto transmission doesn't want to downshift right away if you mash the pedal. There's not a whole lot you can do about that.

The solution, IMO, is just to drive it in Sport mode all the time. Only time I've ever had the car be jerky is either if downshifted to 1st gear, or if I just gave it too much gas. If anything, I love city driving in sport + mode, because you'll get the downshifts everytime you come to a traffic light. :clap2:

I'm planning on installing mine tonight, and I have a question about disconnecting the battery: what, if any, information will be lost or reset when I disconnect it? I'm specifically thinking about nav, memory seats (car is a 401A), stereo info, my color stuff, etc.. If there's anything really important or that takes a while to set up, I'll take a picture of the settings (if possible) before I disconnect the battery. Thanks for the help!

Interesting. My instructions don't say that. I'll try this tomorrow. Is it just the negative terminal then? Did your instructions mention the throttle reset?
Yes. Just the neg my man.

No mention of a throttle reset... I Figured it couldn't hurt

I only have a 400a, but I never had to redo anything. My radio presets were still there, my mycolor stuff still worked, and all that. My radio defaulted on AM Radio instead of USB or bluetooth, but I didn't have to redo any of those.

One time, my clock was off by a few minutes, that was the only thing I had to correct.

So I unplug the battery and it's still the same kind of "lag" I'm feeling. I drove around with the device on on some open road for about 30 mins, mainly in normal mode but sometimes in sport to get some comparison. Here is what I am experiencing.

I think plc is right: the lag I'm feeling now is a function of the auto transmission. The lag that I feel, I take it, is the lag of power?

I will say that the response is better. My foot doesn't need to travel as far to get the response I need. When I removed the device, I noticed that I need more foot travel to get the same response. With the device on, the foot travel is less. So, in a sense, that's good.

And -- someone correct me on this -- the downshift in normal mode is a little faster. Comparing with device on and off, I notice that with the device on, I get the acceleration sooner than with the device off. Am I correct in feeling this?

Overall, I think this will suffice for city driving in normal mode. (Yes, sport+ mode is insane with this device on.) I'm still going to give it a 7/10 (maybe a little higher?). I'll know more about the device after I drive the car a little more. But for now, I feel that it's only OK. Maybe my expectation was very high from the other reviewers. Then again, the others drive in sport or sport+ mode. The driving experience is definitely more intense in those modes.

On a side note, if plc is correct, I wonder if all automatic transmission like this. Do they take longer to downshift? If so, is there anything I can do other than drive in S+ mode?

Thanks.

That is 100% the only thing this device does. It doesn't magically change ECU settings to actually give you more power or "reduce lag". It simply amplifies how much throttle the computer thinks you are giving it. So before the device for example, you push the pedal 20% of the way down, you get 20% throttle. Now, you push it 20% down, you get 40% throttle.

So really, you should be giving the device a 10/10, since it does exactly what it's supposed to be doing, and advertised as doing :thumbsup:

Your entire "lag" problem comes from picking an automatic transmission. With the mushy torque converter, you will never not have some lag. Nothing will ever truly fix this except a proper clutch, just mask it a little bit.

I got mine yesterday. I will put it in tomorrow and report back. Although I drive in track mode 99%of the time so I'm curious how much of a difference it will make.

Yes, I realized this is what is meant. As with a lot of users, it's hard to explain until you actually try it. Well, I tried it, and it's not the experience I thought I would have. As it is said in professional philosophy, you don't know what it is like until you actually experience it. Words can only do so much at explaining this device when this device is really best understood when one experiences it.

Even if the device is working the way it is designed to do, I don't have to give it a 10/10. That rating is based on my sanctification not how well the device works as they claim. Anyway. After driving it for a bit more today, I'll increase it to an 8 or 9 out of 10. But it's your influence as well, that is making me increase it. :cheers:

This device seems to be for cars without the driving modes. The sport plus and track mode also improves the pedal travel and sensitivity. My guess is 100% on the pedal max is equal to track mode in the premium. It makes sense to me.

I have a premium and the device was worth the money and then some. Sport mode feels even sportier and if i do leave it in normal mode, I'll have the sensation of sport mode but without the huge MPG hit.

But what about in track mode? Is there a difference there?

Why wouldn't there be...?

The computer thinks you're giving it more gas. Makes absolutely no difference what mode the car is in. It's simply telling the ecu that the pedal is pushed further than it really is...

So actually in Normal Mode you are burning more fuel than you were before, similar to the sport mode before the application. Still no answer to the snow/wet mode?
