Last night, I headed to the dyno to get my car retuned. First, we did a pull to see what 7k feet will do to a JRSC BBK on SVT.....
Dyno'd at 600ft - 210whp 167tq @ 10psi
Dyno'd at 6,035ft - 163whp !! @ 8psi (thats all you'll get)
Just goes to show you...altitude is no joke.
Anyways, these guys dont do SCT, so I had to switch to diablo predator....
Got the car flashed back to stock via the Xcal2 and then plugged in the Predator. It loaded up my stock tune fine and we then proceeded to flash it with a performance tune....car went dead and showed - - - - on the odo.
I have read of this happening before and I know that the Predator is fickle when it comes to voltage fluctuations. Nothing was turned on or anything, battery is less than a year old, and the fuses were pulled. What could it have been?
So the car sat in the shop overnight till we could get a hold of Mike @ Diablo and force the stock tune back onto the car. According to him, SVTs and Predators are a bit wierd...some like it, some dont. After multiple attempts to get the predator to work with my car, no dice. Same result.
It is believed that it may have something to do with the fact that I was using SCT on the car to begin with. Either way, once back to stock, my SCT flashed the BBK tune back on with no issue.
My deductions are - if your tuner gives you the option of SCT vs Predator, I would seriously consider going SCT. It's just seems like a better option. Not only is it not so fickle, but you can use the LiveLink software to watch your data logging in real time, you can also load more than one custom tune on the device and it will stay there till you delete it.
Predators, to the best of my knowledge will only hold one custom tune and you have to reload it back to the device if you flash back to stock (?) Also, data logging is done directly to the handheld, then viewed either on that tiny screen or you load it to you computer later and watch it. That's just ghey-sauce.
Just wanted to share this experience with anyone who might find themselves trying to decide which platform to go with. Granted, as stated in other posts, it is going to depend on what your tuner uses but if you are given the choice - SCT just seems like a better way to go. I never got the Predator to work with my car and it was brand new out of the box. Also, its nice to use a regular old USB cable to interface between my PC and the SCT vs. having to dick with a serial cable and drivers. SCT just seems more intuitive.
So, in conclusion.....
My end solution - SCT Proracer Tuning Software. Since the shop I want to tune my car doesn't have SCT, I'm looking into buying the proracer package for roughly the same amount as a diablo predator (349 as listed on SCT's site) Apparently, they have been wanting to get the SCT stuff, so they are willing to use my computer w/proracer software, to tweak my car and get a feel for the software.
