totally agree
Like you said, its is not fair to talkabout bhp improvement. Cars with 300 or 400 bhp, the claims may be fair.. but NOT on cars we have in India. Is'nt a rough percentage gains a much better figure? I'm not sure where you are trying to go with that...our top performing product is actually a Tri-Phase for a naturally aspirated PT Cruiser...i'm not sure if you guys have a version of that in your region..dyno gains exceed 20whp gain, and the car is a 4 cylinder. I think for electronic upgrades, the possible gain is more determined by how conservative the factory tuning is, not by the displacement of the motor. Just my personal opinion. And no, I don't think that classifying an entire group of mods with a general percentage range is a good idea. For example, take the Tri-Phase - if we quoted in percentage gains, we would have to quote something like 3% - 18%. 10 whp on an 06 350Z = 3% (tuned pretty much for the track, right from Nissan). 21 whp on a PT Cruiser = 18+% (conservative tuning, for a car that targets people in the 55+ age group). To me, 3 - 18% isn't very descriptive. In fact, its almost pointless to generalize about a particular group of mods, which I believe was my original point.
Since you are discussing products (mods pls feel free to edit if necessary)
Price- Standalones are available for price a little more than your product Point is?
Flexiblity of install - There are standalones that can be plugged in and off i.e. not permanent None of our products are permanent. The Tri-Phase in question can be made completely passive with the flip of a switch.
Driving modes - These standalones also can be switched between "stock" and performance modes Again, I fail to see the point?
The point in question is about claimed percentage gains, not about which product suits better. I think it's a great idea to try and educate people. You have no idea how many calls and emails we get that look/sound like this... "I have a [insert any car here, typically with about 150 hp stock], do you guys have anything that can give me MORE than 20 hp?" And our response is always, no. And in fact, you aren't looking at 20 whp on that vehicle, you are probably looking at 10-12, depending on your operating conditions (elevation of driving environment, atmospheric pressure, relative humidity, air temperature, and the condition of your vehicle. If you, or anyone else here, is trying to insinuate that we overstate our performance gains, that is simply not true. If you think you are going to put 30 hp in your car for $200, you should probably start taking the bus and forget the modding scene.
All the stuff you mention about closed loop AFR control does not apply to all cars. There are many ways to get over them too. Perhaps not in India...but with emissions regulations in the United States, it does. In fact, many mods are considered illegal in many states because they alter the emissions of the vehicle.
With all due respect, going lower than 13:1 DOES NOT CAUSE KNOCK, BLACK EXHAUST or DROP POWER. Sir, have you ever even tried to tune an engine???? 13:1 was not an exact figure...I know you get my point. It's probably somewhere closer to the lower 12's on a naturally aspirated vehicle, depending on the quality of the fuel you have available and the tuning of your particular vehicle. My point was, there is a limit to the amount of fuel you can combust, given the number of oxygen molecules you have to work with. Simple enough?
True regarding overrevving, it should not exceed engine limitations BUT again, its very car specific. Agreed. Both our rev limit and speed limit override modules were discontinued 2+ years ago for liability. It's just not healthy for your motor, and unless your car is strictly for the track (or you have more money than you need), I wouldn't recommend doing it.
a) Almost all cars come OE with narrow band sensors that do not exceed 1000mv at roughly 0.9 to 0.8 lambda.
b) Agree
I still dont see any concrete justification of your product claims. |
