Quite a number of us have been intently involved in the debate / discussion and sometimes could even be described as a slanging match in regard to Unichip or edit. I have not started this thread to start a new fight, but to share my thought process of why ultimately I was more comfortable with the Unichip option instead of the edit process.
Firstly I was originally intent on achieving a high RWKW figure and seeing how much raw power these boss V8’s can put out. For the moment I will not post the RWKW as this is not the ultimate focus of the thread.
Stating the obvious for a moment the drive by wire used by Ford does not seem initially to be as responsive as I had hoped. It sometimes seems as if the car is asking are you sure you really want to go, OK if you’re really sure lets go. Obviously there were times that the response was immediate, but there were also many times when it was not.
Many of us also buy our V8’s for the “note” that rumble that pervades your soul and becomes a craving that you desire every time you start the car up. While the FPV range of V8’s certainly does have a rumble, it is not always present and sometimes not deep enough. This is evidenced by the fact that quite a number of FPV owners have changed to an aftermarket exhaust, or modified to have a dual exhaust. I have a certain problem with throwing out a perfectly serviceable exhaust to put a new one on, however when the current one wears out I may revise my decision.
Enough crapping on about the background, specifically why did I choose a Unichip and not the edit.
Driveability, power consistently across the range that the car is capable of is what I ultimately decided was what I wanted from my car. We could all seek a extremely high RWKW figure, but I ask you at what price. If you have massive power and cannot easily convert that to forward momentum what use is it other than to shred tyres (and at around $350 to $500 a tyre) I do not have that kind of money to piss up against a wall. I drive my car every day it is my car and I want to drive it, not only bring it out on special occasions. It is my firm belief that the real life tune offered as a part of the process of installing the Unichip is superior to an off the shelf “one-size fits all” type approach (being nearly 6ft4in tall I could show you many one size fits all things that don’t even come close.
From reading the posts of other forum members the variability of the cars is their consistency. It strikes me as unusual to say the least that a generic fix could be applied to a non-generic item. I also have extreme reservations with certain aspects of the edit process that could allow the car to operate outside the design limitations built into the design of the car as a package. This is directly a product of the car being built to a budget and not to a specification.
For those of you that believe the edit will not be detectible, dream on and act with some honesty. If you have a problem and you are asked if the car has been edited will you lie or tell the truth.
I had a Unichip installed Monday, I still have a grin from ear to ear it is more than I expected in a positive way. Peter, Rainer and everyone at APS thank you for looking after a very important member of our family and treating it with the respect that I believe it deserves.
My car is a GT-P automatic otherwise unmodified. Now to the ultimate test, what is it like to drive on the road. Smooth acceleration whenever you ask for it, there is no delay in the response. It does feel more powerful, but in a controlled way, it is useable wherever you need it. Tyre spinning is no more an issue than previously. The rumble is more pronounced at idle and while driving, but is not a drone at any speed even on the freeway yesterday into the city. The car feels more responsive and it is even more enjoyable to drive, it is like getting a new car that is even more enjoyable to drive, and I didn’t think that it would be possible. I love my car even more now.
To any other person that is thinking of going down the same track, my personal opinion is do not be fooled by the “smoke and mirrors”. Do your own research, ask questions and make any one working on your car justify to you beyond any doubt that to do whatever to your car would be a good thing and not a step backwards, or even sidewards.
Steven , get back to us in a month and see if you are still feeling as well , I agree a one size tune will not suit your or any other vehicle , that is why we now have tuning software so we can cater a edited tune to suit your vehicle , we have control of all parameters such as throttle response whereas the unichip can only put a offset onto a signal to try and trick the pcm.
The closest analogy I can use is how you would treat your girlfriend - try and trick her by trying to decieve her and she will learn that pretty quickly and bite back , but on the other hand tell her what is going down and she has two options - piss off or accept it whether she likes it or not.
Same with a engines PCm , command it to do something and it has no choice but to obey ( at least they cant say no ) try and trick it and it will learn that something is wrong with the signals it is getting and it will look for backup signals to verify and use if the other signal is out of the expected range.
Unichip is a ok thing when there are no other choices - why would APS bother developing thier edit if the unichip was the be all and end all of tuning.
The only advantage it has at present is a quicker tuning time , but given that we spend months developing a base tune for each vehicle then modify it to suit each vehicle on the day we are tuning - normally each car takes the better part of the day to get it tuned to our satisfaction.
