i don't know how long you guys planned to drag this thread off. there's already an answer for the question.
1) How PS Powersport works?
Nobody knows. It doesn't take a degree to figure it out that every answers by ps users doesn't indicate that they know about the inner working of the product. No matter how you push it, they won't know. So live with it. Not satisfied? Go tell your mommy.
2) How PS Powersport users claim that the product is better than standalone?
It's their satisfaction. If they have tested a product that doesn't work, and then PS Powersport solved their problem, they will tell the whole world how good the product is. Sometime exaggeratingly annoying. That's natural for a human being. Not satisfied? Go tell your mommy,one more time.
Whether any standalone/piggyback comes with manual/specs or not, we judge for which one is working fine. Judging from the users, there are high possibility that this product will works. But it comes with one big disadvantage, it will not tell you how. I'm the type of person, who depends heavily by the result. If it will do the job, i will accept it even the brand is somewhat unknown. There are already plenty of people who already put this product inside their car. If you want to know more, just go check their ride. Get up your lazy as* people!
The fact that none of the PS users know how the product works means that the there is no answer and therefore until a satisfactory one is presented here, I doubt this thread will go away. From my understanding, PS products work just like any of the other piggyback products by tricking the ECU however being totally analogue the claim is that PS products allows for more instantaneous adjustments while tuning.
For example if one were to use a laptop, despite the advancements in technology etc it does take sometime for the signal from the AFM to be converted and displayed on a laptop after which the tuner makes the adjustments etc. However, for PS products because its entirely analogue, there is no conversion of the signal from the AFM to binary to be displayed on PC after which the conversion is reversed back to a signal which the ECU is then able to read and then the necessary adjustments actually take effect. This all happens in seconds or microseconds even. PS on the other hand would be tuned with the tuner actually turning the knob while getting his reading or monitoring using devices such as an oscilloscope for example which although might be perceived as rudimentary, is actually giving you a direct signal almost instantly.
Having said that, there are PS products that do make sense and some which do not. The voltage stabilizer for the fuel pump is one such device which I'm not convinced. The argument is that all fuel pumps need 13.5v or so to flow at their optimum rate however a lot of fuel pumps do not flow at the rate they claim regardless of whether they receive the 13.5v or not. In cases where there is a voltage drop, then the flow drops by a large amount. Supposedly PS is able to alleviate this problem by pumping a high voltage to the fuel pump which I'm not convinced will not affect the longevity of the actual pump itself.
One PS product that does make sense and is in fact impressive is the blow off valve. To go into detail as to why its superior would take awhile and best shown using pictures of it disassembled side by side with other brands such as Turbosmart for example. I'll try and get some pictures as my explanation would not do the product any justice, not for the bargain price it retails for unlike the other PS products.
Moving on, what concerns me about the PS products and more importantly the way they are tuned is the fact that the cars are not tuned on dyno. I for one would want, or rather need to know when peak power is being produced as it would affect the point where I change gears. Without this type of information, how does someone in drag racing for example know he's shifting at just the right point? Also, without the use of dynos how does anyone know how much power a certain car is producing and really can it be said that whatever power achieved is the absolute optimum power? How can we be sure that a standalone ECU wouldn't produce better results unless a back to back test is performed. For PS users, they're happy because the car runs well - of course it does as the stock ECU is running pretty much everything bar the functions that the PS product is manipulating.
Another thing that puzzles me is the pricing of PS products which I find to be ridiculously high. I don't see the justification for such high pricing because firstly the product is outdated, no new R&D is being done and whatever costs incurred developing the product many many years ago should have been recouped by now. Also the presentation of the product is.. well really shit. It looks like something from the late 80s early 90s, cost in the thousands and lack proper presentation. I'm quite puzzled how most PS users claim to be able to tune without even a user manual to refer to - must have some hidden talent.
So for people like perompak_bank who would like us to get off our asses, I find it ironic that as a user he knows practically nothing about the product while I as a non-user pretty much have clear understanding of how the product works for the most part. Your statement reeks of ignorance and hypocrisy and sadly added absolutely no value to this discussion. But thanks for stopping by, you've proven yourself to be a typical PS user.
