Hi everyone,
I'm reaching out for a sanity check as I'm dealing with a situation with SCT.
When I had my non-PP 2016, mashing the gas would always cause the trans to kick down, even in manual control. Once I got my PP 2016, I discovered that the kickdown/downshift was disabled while manually shifting (shifter has to be in S as well). The same was true of my Gearhead tune. Can anyone please corroborate this difference between the PP and non-PP, that my car is not just an anomaly?
Feel free to skip the novel I'll probably turn the rest of this into. For context, I've bought SCT's tuning software, which btw is absolute garbage and literally unusable by itself to tune these vehicles. Thank you HPTuners for offering free demo software that can do what SCT's $350 paid version can't!
Among the list of their numerous flaws (which I won't get into right now) is that they don't give you the ability to upload a tune from the vehicle but rather you have to start with the "stock" tune they provide within their database or whatever. Well, after flashing my first adjustments I found I couldn't hold a gear without the car kicking down on me.
Okay, that by itself is no big deal. I know how to change it. BUT, what it proved to me is that what they deem as my car's stock tune ain't actually my car's stock tune. Now, there's probably nothing worth worrying about. But knowing that they gave me a non-PP calibration makes me wonder about any differences there may be in the trans tables, shift scheduling, torque limits, etc due to the different gear ratios.
So, I emailed SCT explaining my observations and concerns. I attached the .bef file (the stock calibration) from my livewire, and asked for the ACTUAL stock tune for my vehicle to work with. I also inquired at that time if they had any resources to actually be able to tune the speed density coefficients, as I felt I was missing something. They were pretty quick to respond, and I even had to give them props for getting back to me on a Sunday!
Unfortunately, though, the nameless individual who responded was more interested in trying to troubleshoot the kickdown issue with me. I responded letting them know I had that part figured out already, reiterated that I would like to use my actual stock tune as my starting point (who wouldn't?) and asked a 2nd time if they had anything for tuning the speed density system of the car. From that point on, it's been absolute silence from them. I've sent a few different emails over the last couple weeks and I can't ANY response from them. I even said 'if the answers are no then just tell me no' and got nuthin'.
Then earlier this week I decided I wanted to go back to true stock to log a few things. So I swap the MAP sensor and return to stock through the livewire. Guess what folks? My "stock" car can't hold a gear any more! So not only does SCT and their software not allow me to tune MY vehicle using MY factory calibration, their junk literally erased/overwrote my car's stock tune with their own version of "stock"! This can actually be observed while programming the livewire as one of the steps is "writing stock ecm" or something like that.
I just sent off yet another email explaining the current development. We'll see if they respond but at this point it seems highly unlikely.
